ATOLL RESEARCH BULLETIN NO. 392 THE FLORA OF NAURU RR THAMAN, F.R FOSBERG, E L MANNER AND D.C. HASSALL ISSUED BY NATIONAL MUSEUM OF NATURAL J!WTORY SMllTJ!WNIAN INSTlTUTION WASHINGTON, D.C, U S A FEBRUARY 1994 DEDICATION We dedicate this Flora of Nauru to Joseph Detsimea Audoa, his family and the people of the Republic of Nauru who have had their precious island and its flora destroyed and degraded as a result of wars and exploitation beyond their control. ACKNOWLEDGEMENTS The authors would like to acknowledge, in particular, the late Honorable Joseph Detsimea Audoa, the Minister of Health and Education at the time of the commencement of the study and later Minister of Justice in the Government of Nauru, who, because of his vision and commitment to the culture and environment of Nauru, initiated and provided the financial support for the study of the flora of Nauru. He was particularly concerned that the plants of Nauru and their cultural uses be recorded before such knowledge was lost. We also acknowledge Mr. Lisle Newby, the then Director of Education, who, along with Joe Audoa, were the main supporters of the project, and who provided valuable logistical support throughout. Special thanks are also given to our main local informants and assistants, the Reverend James Aingimea and the late Henry Michael Heine; and to Daphne Fotu, Jacob Gabwinare, Katarina Satto, Kenia Raidinen, Reynold Capelle, Eda Adam and Montiba Star, our main informants in relation to the cultural uses and Nauruan names of plants. Our thanks also go to the Honorable Lawrence Stephen, Minister of Education during part of the project; Obera Menke, Robert Kaierua, Leo Keke, Delilah Capelle, Eddie Borak, John Healy, Gary Bailey, Dennis and Ria Berdinner, Julie Olsson, Dennis Ketner, Sio Fotu, Pine Harrison, John Brechtefeld, Rene Harris, Porthos Bop, Jacob Aroi, Leon Thompson, Benjamin Morgan, Iosefa Elisala and Teaora Tabanou, all of whom contributed in some way to the success of the study. To others who helped in any way during our study, we also give thanks. Thanks are also due to those people, who over the past 100 years, have collected and identified plants on Nauru; and to Saula Vodonaivalu of the South Pacific Regional Herbarium of The University of the South Pacific, Suva, Fiji who identified, preserved and is the curator of the herbarium specimens collected by Thaman, Manner and Hassall. Without their efforts, this flora, would have been impossible. Similarly, we would like to thank The University of the South Pacific for the support it has provided throughout the duration of the study, both as the institution where the study was initiated and completed and as Nauru's own university of which it is one of twelve regional member countries. In addition to the above acknowledgements, Fosberg wants to mention the substantial assistance given him during his week-long visit to Nauru in 1983 This visit was at the invitation of Mr. Richard Wood, accountant for the Nauru government, who made the arrangements for the visit and who served as guide during the first day, reaching areas not otherwise accessible. The success of this visit was also made possible by transport and guidance by Mrs. Joan Nichols of the Australian High Commis- sion's office. In her company much of the interior of the island and some of the local gardens were visited and many plant specimens were gathered. The success of this visit was largely due to the two people mentioned above, and their company in the field was much enjoyed and appreciated. Many thanks! Finally, we wish to express our heartfelt thanks to the people of Nauru whose warmth and hospitality made our work on their beautiful but damaged island so enjoyable and worthwhile.

THAMAN1, F.R. FOSBERG2, H.I. MANNER3 AND D.C. HASSALL4 PART I. INTRODUCTION AND ANALYSIS OF THE VEGETATION AND FLORA The recorded flora of the raised phosphatic limestone island of Nauru in the equatorial Pacific Ocean consists of approximately 493 species. Only 59 are possibly indigenous, none of which are endemic. The balance is composed of ornamentals, weedy exotics, food plants, and a limited number of other useful cultigens. Twelve of the recorded species are either extinct or were never successfully established on Nauru. Long human settlement, expansion of coconut monoculture during the colonial period, widespread destruction during World War 11, and almost a century of open-cast phos- phate mining, have led to serious vegetation degradation, disturbance, and displacement l .

Although greatly outnumbered by exotics, indigenous species still dominate some of the most disturbed habitats, as well as constituting the most culturally- utilitarian and ecologically-importan t species. The flora is in two parts. PART I: INTRODUCTION AND ANALYSIS OF THE VEGETATION AND FLORA, includes a brief discussion of: 1) previous studies and the current study; 2) the physical environment, people, development history and contem- porary economy of Nauru; 3) the nature of the existing flora and vegetation associations of Nauru; and, 4) an analysis of the ecological and cultural importance of the flora in the context of modern small-island development. PART 11: A COMPILATION OF THE VASCULAR FLORA OF NAURU, consists of a listing of all vascular plants reported to have been present on Nauru, along with relevant information on each species. Although a number of persons have collected plants on Nauru over the past century, this constitutes the first extensive flora the of vascular plants of the island. The plants are listed in alphabetical order by family and species within families, starting with the ferns and gymnosperms and then angiosperms, with monocotyledons listed first. Information on each species, variety or subspecies includes: 1) scientific (Latin) name and synonyms; 2) common (mainly English) name (s); 3) Nauruan, Kiribati, Tuvaluan, Chinese (Cantonese), Filipino and Solomon Island names, when available; 4) origin; 5) antiquity status (i.e., whether a species is indigenous to Nauru, an aboriginal introduction, an early post-European-contact introduction or a recent post-World War I1 introduction; 6) its status in terms of abundance (i.e., whether it is abundant, common, rare, extinct, etc); 7) a detailed botanical description; 8) its habitat or distribution on Nauru; and 9) its cultural or ethnobotanical importance. PREVIOUS STUDIES Although collections and observations of the flora have been made on Nauru by Finch prior to 1900; Burges in 1933; Fosberg in 1980; Scully in 1980; Thaman, Hassall and Manner in 1980 and 1981; Thaman and Manner in 1987; Swarbrick in 1988; and Raulerson in the early 1980s, little has been published. The only substantial publications on Nauru's vegetation include studies by Manner, Thaman and Hassall (1984 and 1985) on vegetation changes induced by phosphate mining; a list of Nauruan plant names by Thaman, Manner and Hassall (1985); and the "Vegetation of Nauru and the Gilbert Islands" by Thaman (1992). Fosberg, Sachet and Oliver's "A geographical checklist of Micronesian Dicotyledonae" (1979); "Geographical checklist of Micronesian Pteridophyta and gymnosperms" (1982); and "A geographical checklist of the Micronesian Mono- cotyledonae" (1987), are also important and list most of the species cited and specimens examined prior to 1980. CURRENT STUDY The current study is based on an in-depth analysis of the above sources; five- weeks fieldwork, including two visits by R.R. Thaman, H.I. Manner and D.C Hassall of The University of the South Pacific, Suva, Fiji in Nauru in 1980, 1981; one week each by Thaman and Hassall in 1987; and a three-day visit by F.R. Fosberg of the Botany Department of the Smithsonian Institution, Washington, D.C. in 1987. During these visits herbarium specimens were collected and identified and the Latin and vernacular names of all plant species recorded and listed alphabetically. These lists were then cross-checked, consolidated, amended and augmented, both during and after the field studies, using lists and names from previous studies. Information was also collected on the cultural uses (ethnobotany) of the flora. BACKGROUND ON NAURU Physical Environment The Republic of Nauru is an isolated, uplifted limestone island located 41 km south of the equator at 166 deg 56 min E longitude, some 2000 km east-northeast of Papua New Guinea, 4450 km south-southeast of the Philippines and an equal distance to the southwest of Hawaii. The nearest island is Banaba (Ocean Island), 300 km due east, which is part of the Republic of Kiribati. The Gilbert Islands, the main islands of Kiribati, lie a further 400 km to the east. The island, with an area of only 22 km2, consists of a narrow coastal plain, ranging from 50 to 300 m wide, encircling a limestone escarpment rising some 30 m to the central plateau (See map of Nauru). The escarpment ranges in gradient from vertical cliffs to gradually-sloping areas of colluvial soil interspersed with limestone outcrops and pinnacles. The plateau, with a maximum elevation of 70 m, consists of a matrix of coral- limestone pinnacles and limestone outcrops, between which lie extensive deposits of soil and high-grade tricalcic phosphate rock (Viviani 1970, Tyrer 1963). Buada Lagoon, a landlocked brackish lake, and its associated fertile depression (about 12 ha in size), is located in the low-lying southwest-central portion of the island. Apart from Buada Lagoon, there are no surface freshwater resources on Nauru, although there are a few brackish ponds on the northeast of the island and an under- ground lake in Moqua Cave in the southeast (Viviani 1970:4). The only significant permanent freshwater resource is groundwater in the form of a "lens" of often slightly brackish freshwater, hydrostatically "floating" on higher density saltwater beneath it. The height of the freshwater - - -- lens above sea -- level -- and the - - - - level of - salinity vary -- in - relation to the-elevation, geology, texture and shape of the island, and with theamount of water use and rainfall. Replenishment or recharge of the lens is dependent on rainfall. Climatically, Nauru is located in the dry belt of the equatorial oceanic zone, with mean daily temperatures ranging from 26 to 32?C. Annual rainfall is extremely variable, averaging 1500 mm per year with a range of 300 to 4572 mm. Severe prolonged droughts are common and place severe stress on even the most hardy coastal strand species, lead to the death of non-coastal exotics (such as breadfruit), and severely restrict the production of even coconut palms (Catala 1957). For example, in 1917 and 1918, during an unprecedented drought, when only 465 and 483 mm of rain fell, "thousands of coconuts and other fruit trees died" (Griffiths 1923). The coastal soils of Nauru are among the poorest in the world. They are shallow, alkaline, coarse-textured and have carbonatic mineralogy. They are composed of a variable layer of organic matter and coral sand and fragments, which overlay a limestone platform. The coastal soils are only about 25 cm deep, and contain more coral gravel than sand in the lower horizons. Potassium levels are often extremely low, and pH values of up to 8.2 to 8.9 and high CaCO, levels make scarce trace elements, particularly iron (Fe), manganese (Mn), copper (Cu) and zinc (Zn), unavailable to plants. Fertility is, therefore, highly dependent on organic matter for the concentration and recycling of plant nutrients, lowering soil pH, and for soil water retention in the excessively well-drained soils. Although levels of organic matter can be relatively high in undisturbed soils under natural vegetation, it can decrease dramatically as a result of clearance by fire or replacement by coconuts and other introduced plants (Morrison 1987ab). The plateau soils of Nauru vary from shallow soils, on the tops of limestone pinnacles, composed primarily of organic material and sand or dolomite, with very little phosphate, to deep phosphatic soils and sandy phosphatic rock, up to over 2 m deep between the pinnacles. Topsoils range from 10 to 25 or 30 cm in depth, overlaying a deeper material which is frequently reddish yellow and between 25 and 75 cm deep, changing to pinkish grey at greater depth. Undisturbed plateau soils have a high level of organic material and are generally fertile. Calcium dominates the exchange complex and exchangeable magnesium is also high. Exchangeable potassium is low, while extractable phosphate values are generally high and sulphate moderate. The trace elements man- ganese, copper, cobalt and molybdenum levels are very low, and these, plus iron and zinc, are rendered unavailable to plants under pH values >6.5 (Morrison 1987b). Around Buada Lagoon and in some poorly drained swampy areas near the base of the escarpment on Nauru, there are poorly developed, but relatively fertile, wet soils. The People The indigenous people of Nauru are Micronesians, who have probably inhabited the island for up to 3000 *I% ormore. Txere% some evi-dence of Melanesian, and possibly Polynesian, influence. The Nauruan language is quite distinct from all other Pacific languages, reportedly a fusion of elements from the Gilbert, Caroline, Marshall and Solomon Islands. Early this century there was evidence of distinct racial types or groups of mixed origin. The people were divided into twelve distinct, originally totemic, matrilineal clans, most of which spoke different dialects, some of which were still in evidence when trying to obtain vernacular plant names in the early 1980s. However, most dialects have become obsolete, having been replaced by the principle dialect, which was used for Bible translation by European missionaries early this century (Viviani 1970:4-7). The traditional subsistence economy of Nauru was based on coconut and pandanus as the main staples, a limited range of wild terrestrial food products, sea birds, such as the black noddy tern (Anous tenuirostris) and a very wide range of fish and other marine foods. Milkfish or ibija (Chanos chanos) fry, collected from the reef at low tide, were farmed in family-owned divisions of Buada Lagoon to provide fish for special occasions and when other supplies failed. Their housing, tools, clothing, medicines, fuel, fishing equipment, canoes, dyes, ornamentation, perfumes, toys and other material and many of their non-material needs were satisfied from their environment, especially from plants. The Nauruan population suffered from introduced diseases against which they had no natural resistance, and from incessant tribal warfare, with Nauruans numbering only 1250 in 1910, a decline of 150 from the total of 1400 in 1840 and 300 less than recorded in the German census in 1905 (Viviani 1970:37). The estimated population of Nauru in the most recent census in 1983 was 8042, of whom 4964 were Nauruan, with the balance comprised mainly of I-Kiribati (people of Kiribati, formerly the Gilbert Islands of the British Gilbert and Ellice Islands Colony), Tuvaluan, Chinese, Filipino or Solomon Island contract workers in the phosphate industry. There are also European, Indian and Pacific island expatriates working mainly for the Nauruan Government. The Nauruans live on the coastal strip and around Buada Lagoon, the phosphate workers in the Nauru Phosphate Company dormitory accom- modation at Location near the phosphate loading cantilevers, and the expatriate civil servants in residential areas on the escarpment. The town center is located between the airport and Location near the cantilevers (Figure I), with most government offices near the airport. Development History After the first recorded European sightings of Nauru by John Fearn of the British Ship Hunter in 1798 who named it "Pleasant Island", there was little regular contact with the island until the 1830s when British and American whalers made regular stops for water and food, and beachcombers arrived. The beachcombers, with the introduction of new weaponry, intensified a period of almost incessant clan warfare. At the time of the beginning-of- formal d o n i d - influence--when Nauru was incorporated into Germany's Marsha11 Islands Protectorate in 1888, the island "had the appearance of a battlefield" (Viviani 1970:22). In 1919, after WorId War I, Nauru became a League of Nations mandate of Great Britain, Australia and New Zealand, administered by Australia. Nauru became independent in 1968. Apart from the provisioning of whaling vessels, mainly with fish, pigs and coconuts, the first regular non-traditional economic activity was a sporadic copra trade established in the 1880s. By the late 1880s Nauru produced about one million pounds of copra annually, one of the main reasons that Germany, on the recommendation of resident German traders, annexed the island in 1888. In the 1890s, due to drought and infrequency of ships, the copra trade failed to reach its potential with Nauruans refusing to make more copra than needed to pay their taxes (Viviani 1970; Carter 1984). The strategic and economic importance of Nauru increased dramatically with the discovery, in 1900, of high grade phosphate rock, containing up to 78 per cent tricalcic phosphate. The mining of phosphate, without approval of the indigenous inhabitants, began in 1907. Caroline Islanders and Chinese contract-laborers were recruited to mine the deposits. Since then, I-Kiribati, Tuvaluan, Filipino and Solomon Islands contract workers have been recruited to work in the phosphate industry. The deposits have been mined continuously since 1907, except for disruptions during World War I and again during World War 11. Copra production continued to fluctuate, with over 300 tons having been exported the year before the phosphate trade began in 1906, 277 tons in 1916, and falling to only 10 tons in 1918 due to a prolonged drought (Viviani, 1970: 22-38). With the beginning of the phosphate trade, the whole pattern of Nauruan life began to change. Although barter continued, money became the medium of exchange, and trade stores with their array of goods, further encouraged the trend. As Viviani (1970:38) argues: Old crafts such as mat making began to be forgotten as woven materials become available. Rites and customs were debased. Faced on all sides by the white man's attempt to dominate their environment and the disintegration of their culture, the Nauruans sought a new orientation for their lives. They could no longer follow the old ways completely and so settled for a combination of the basic elements of the old culture, clinging strongly to their family life, and some of the advantages of Western civili- sation. They were able to achieve this because, although royal- ties were low - only about 230 Pounds Sterling per annum at this time for the whole population - this money, together with land rents and some return from copra, freed them from the necessity of working on the phosphate fields to pay their taxes. The most disruptive period for Nauru was World War 11, during which the island was cnntinuously bombed b y Japanese- and Americans planesJ3eginning in 1940,five phosphate vessels were sunk off Nauru and the island shelled by German warships. Nauru was again bombed by Japanese planes in 1941 and 1942 prior to Japanese occupation of the island. After a Japanese military airstrip was completed in 1943, the island was bombed almost continuously by Allied planes. By the end of 1943, due to the importation of at least 3000 Japanese marines, some 1500 Japanese and Korean laborers, and the relocation of 700 Banabans to Nauru, the food situation became so serious that 1201 Nauruans, seven Chinese and two priests were deported to Truk. Malnutrition and dysentery were widespread. Allied bombings increased considerably until the Japanese surrender to an Australian occupation force in 1945. At this time, of nearly 5200 people, only 591 were Nauruan, and the destruction of the phosphate works and buildings on Nauru was almost total. The 737 Nauruans who had not died under the harsh conditions imposed by the Japanese in Truk returned home in 1946 (Viviani 1970; Carter 1984). As argued by Viviani (1970:85): The Japanese had destroyed the Nauruan's homes, schools, and churches, placed them on a semi-starvation level and destroyed much of what was left of their old way of life. The deportation of two-thirds of the Nauruans and the death of nearly 500, mostly the old and the young, left the society after the war with a gap in generations and a disruption of family life. Again the Nauruan population had fallen well below the 1,500 level which the Nauruans themselves regarded as a minimum for survival. Contemporary Economy Nauru's sole export continues to be phosphate, with the sporadic export of copra having ceased in the 1950s. Phosphate earnings have made Nauru among the wealthiest nations in the world in terms of per capita income, although the distribution of wealth is uneven due to unequal land rights to phosphate deposits. Nauru is considered totally urbanized, with Nauruans having almost completely abandoned subsistence production, except for the harvest of coconuts and pandanus fruit for consumption; pandanus leaves for plaited ware; the acquisition of fish and other seafood; and the hunting of noddy terns, which are considered a delicacy of chiefly status, and the capture and caring for of frigate birds as pets, both traditional pastimes. Most of the limited subsistence agricul- tural production is in the hands of immigrant communities. The establishment of its own heavily subsidized international airline, Air Nauru, in 1970, which flies to Asia, Australia, New Zealand and other Pacific islands, and the extension of the runway over the reef have accelerated the processes of urbanization and an increasing dependence on imported products. Of concern is the impact that the destruction of the traditional subsistence food system, rapid urbanisation and the almost total dependence - - - on - -- nutritionally-poor - -- imported food and drink, including extremely high rates of alcohol consumption, have had-on thehealthof ~auruans, which have the among highest or most rapidly increasing rates in the world of obesity, dental disease, al- coholism and nutrition-related non-communicable diseases such as diabetes, cardiovas- cular disease, gout and hyperuricemia and liver cancer. All are causes of premature mortality (Zimmet et al. 1977, 1978; Speake et al. 1979; Taylor 1983; Coyne 1984; Thaman 1982, 1983, 1985, 1988a). In terms of Nauru's economic future, the phosphate deposits on Nauru are projected to be depleted shortly after the turn of the century. Fortunately, a significant proportion of recent phosphate returns have been wisely invested in overseas properties, businesses and investment funds to provide income in post-phosphate-mining Nauru. A further source of income is derived from Nauru's status as a "financial center" or "tax haven" for overseas companies wishing to register there. Finally, negotiations and litigation arising out of a recent Commission of Inquiry into the Rehabilitation of the Worked-out Phosphate Lands in Nauru to determine culpability and the extent of damages to the Nauruan culture and environment are currently in process and could lead to substantial payments to Nauru and the development of plans for the rehabilitation of the island. Impact on the Flora Due to environmental factors described above - extreme isolation from major plant source regions, small island size, extremely poor soils, and climatic and physiological drought - the indigenous flora of Nauru is among the poorest and most restricted on earth. Moreover, the long settlement history, widespread destruction during World War 11, monocultural expansion of coconut palms as the sole cash crop, increasing ur- banization and contact with, and importation of plants from the outside world, and over 75 years of open-cast phosphate mining (in Nauru and Banaba), have all played a role in the serious degradation, disturbance, and displacement of the indigenous flora and vegetation. VEGETATION TYPES The terrestrial primary vegetation types of Nauru are limited to: 1. coastal strand vegetation; 2. limited areas of mangroves and coastal marsh vegetation; 3. relict stands of inland forest; and, 4. limestone escarpment or pinnacle vegetation. Secondary and cultural vegetation types include: 1. coconut-palm-dominated lands under various degrees of maintenance; 2. houseyard gardens and urban vegetation; 3. extensive and variable areas of ruderal vegetation; and, 4. three-quarters of the entire island under severely-modified disclimax vegetation in various stages of succession after some 80 years of open-cast phosphate mining. These vegetation types will each be described in turn. Coastal Strand Vegetation The coastal strand vegetation of Nauru has been severely modified as a result of: 1) thousands of years of human habitation and selective removal of indigenous species for construction, boatbuilding, firewood and other purposes; 2) the expansion of monocul- turd coconut groves for export production of copra; 3) the expansion of coastal set- tlements which occupy most of the coastal plain; and, 4) the widespread practice of allowing pigs to forage freely along beach flats (Viviani 1970). The dominant species in the outer coastal zone in Nauru include the herbaceous species Lepturus repens, Cyperus javanicus, Ipomoea pes-caprae and Vigna marina; the woody species, Scaevola taccada, Tournefortia argentea and Morinda citrifolia, plus the aboriginal introduction, Cocos nucifera. Species common on rocky limestone outcrops along the coast include the same species plus Polypodium scolopendria, Capparis cordifolia, Clerodendrum inerme, Terminalia catappa and Calophyllum inophyllum. Species present on non-rocky, somewhat disturbed inland coastal sites between the strand and the base of the escarpment include Hibiscus tiliaceus, Cocos nucifera, Premna serratifolia, Calophyllum inophyllum, Pandanus tectorius, Morinda citrifolia, Terminalia catappa, Ochrosia elliptica, and isolated specimens of Barringtonia asiatica, Thespesia populnea and Hern.andia nymphaeifolia. Shrubby species include Scaevola taccada, Colubrina asiatica, Abutilon indicum and Phyllanthus societatis; herbaceous species include Cyperus javan.icus, Digitaria setigera, Vigna marina, Ipomoea macrantha and the ferns, Polypodium scolopendria and Nephrolepis biserrata. Caesalpinia bonduc, Euphor- bia chamissonis, Sida fallax and Triumfetta procumbens are scarce, but were probably more abundant in the past. Mangroves and Coastal Marsh Vegetation - Shallow--water habitats with muddy- bouoms and protected from strong wave action are extremely limited on Nauru. Although reportedly present in the past around Buada Lagoon, Nauru's single mangrove species, Bruguiera gymnorhiza, is ROW restricted to a system of landlocked brackish ponds or small lagoons near the base of the escarpment in Menen, Anabar and Anetan Districts. The largest concentration is found around Araro Lake in Anetan. Fosberg (c. 1972) also reports the occurrence of B. gymnorhiza in similar landlocked ponds, sink-holes and small inland swamps in Palau. Other species commonly associated with mangroves and present in Nauru include Derris tnifolia, encountered on limestone outcrops, and Vitex negundo, which is present in depressions near the base of the escarpment in Menen District. The swampy areas surrounding Buada lagoon and near the base of the escarpment on Nauru are dominated by Cyperus javanicus and C. compressus, with one specimen of Ludwigia octovalvis collected from a coastal depression. Relict Stands of Inland Forest In terms of relict stands of primary inland forest on Nauru, there seem to be two distinct types: 1) plateau forest, which probably covered up to 90 per cent of the island before the onset of phosphate mining, and 2) escarpment forest, including forest on unmined limestone outcrops or pinnacles on the plateau. The former, four-fifths of which has been removed during phosphate mining, is dominated almost entirely by 16 m-tall Calophyllum inophyllum. Infrequent canopy trees include Guettarda speciosa, Premna serratifolia and Terminalia catappa, with the understorey dominated by Scaevola taccada, Morinda citnifolia and Dodonea viscosa, the parasite Cassythafiliforrnis, Psilotum nudum, and the ferns, Polypodium scolopendria and Nephrolepis biserrata. Also occasional in open sites is Phyllanthus societatis. Exotic species dominant in disturbed sites include Psidium guajava, Lantana camara and two herbaceous species, Euphorbin hirta and Desmodium triflorum (Manner et al. 1984, 1985). Limestone Escarpment or Pinnacle Vegetation The dominant species on the limestone cliffs of the escarpment and on emergent pinnacles on Nauru is Ficus prolixa, with Terminalia catappa, Ochrosia elliptica and Guettarda speciosa constituting important second stratum species (Manner et al. 1985). Isolated relict stands of Barringronia asiatica and Pisonia grandis are also found along the crest of the escarpment above Anibare Bay. The ferns, Nephrolepis biserrata and Polypodium scolopendria, and the liana, Ipomoea macrantha, are locally abundant, and the herb, Laportea ruderalis, is found in moist shady habitats at the base of the es- carpment. On the more gradually-sloping colluvial portions of the escarpment almost impenetrable-thiekets of--HibisewtiZ&e are- found, Uqde~storey- specks include Colubrina asiatica and Tacca kontopetaloides. In Anetan District, in the north (Figure I), Clerodendrum inerme festoons limestone outcrops and cliffs. In some areas the exotic fruit trees, soursop and sweetsop (Annona muricata and A. squamosa) have become naturalised and constitute the dominant understorey species. Coconut-Palm- and Pandanus-Dominated Agricultural Lands As stressed above, coconuts and pandanus were the two most important staple crops in pre-European-contact Nauru. Coconut groves, although far less important today than in the past when copra was the main export, are still found in a number of sites on Nauru's coastal strip. In most cases, the plantations are comprised of randomly scattered trees of varying heights and ages. In poorly-maintained groves, coconut seedlings and fallen leaves and husks dominate the understorey. Planted groves of edible Pandanus tectorius cultivars in forest clearings, both on the plateau and on the more gradually sloping areas of the escarpment, were also once a prominent feature of Nauru's traditional agricultural vegetation. Today, they are restricted to a few relict groves, some of which were found to be present in the unmined areas of Anibar District in 1980. Houseyard Gardens and Urban Vegetation Although indigenous and aboriginally introduced species are important com- ponents, most houseyard gardens and urban vegetation are dominated by recently introduced exotic species. The high diversity of recently introduced exotics in Nauru is due mainly to the almost complete destruction of the subsistence economy, urbanization and increasing air transport contact with overseas sources of non-quarantined planting materials. In indigenous Nauruan houseyard gardens the dominance of recently introduced ornamental species is very pronounced, with some 118 of 140 species being classified as recent introductions. Indigenous species include Abutilon indicum, Barringtonia asiatica, Calophyllum inophyllum, Cerbera rnanghas, Clerodendrum inerme, Cordia subcordata, Ficus prolixa, Guettarda speciosa , Morinda citrifolia, Ochrosia elliptica, Premna serratifolia and Terminalia catappa, which in some cases, such as with Cerbera manghas and Cordia subcordata, are only present today in Nauru in houseyard gardens. Common food plants include, in order of importance, coconut, breadfruit, bananas, pandanus, papaya, Citrus spp. and guava. Common ornamentals, found in at least four of 16 sample gardens, include Acalypha amentacea vars., Bougainvillea spp., Caesalpinia pulcherrima, Caladium bicolor, Casuarina equisetifolia , Catharanthus roseus, Codiaeum variegatum, Cordyline fruticosa, Crinum sip., ~e lonix -- - -~~ regia, ~ Dicfenbachia ~ ----- - ~~ spp., ~ i b i s & ~ rosa- sinensis, Hosta plantaginea, Hym.en.ocallis littoralis, Ixora spp., Jasminum samba~, Jatropha integerrima, Nerium. oleander, Pen.tas spp., Plumeria spp., Polyscias spp., Pseuderanthemum. carruthersii, Sansevieria trifasciata , Tabernaemontana divaricata , Tecoma stans and Th.un.bergia erecta. The houseyard gardens of I-Kiribati, Tuvaluan, Chinese and Filipino contract workers, and in the European and Indian expatriate communities of Nauru, are very different. Each reflect distinctive preferences in food and ornamental plants, and are commonly dominated by food plants. I-Kiribati and Tuvaluan gardens at Location, where there is very little space for planting, usually consist of a single banana, coconut, papaya or breadfruit tree, or a few cassava, sweet potato, taro, tannia (Xanthosoma sagit- tifolium), pineapple, sugarcane, hibiscus spinach (Hibiscus manihot), or chilli (Capsicum frutescens) plants. All are often grown in boxed or fenced areas filled with imported soil or mulch. Chinese gardens at Location focus more on short-term vegetable plants, such as Chinese cabbages (Brassica spp.), onions and garlic (Allium spp.), amaranth spinach (Amaranthus spp.), coriander (Coriandrum sativum), long beans (Vigna sesquipedalis) and a range of cucurbits. Filipino workers plant sweet potato, hyacinth bean (Dolichos lablab) and horseradish or drumstick tree (Moringa oleifera). European expatriates plant tomatoes, lettuce and parsley, whereas the expanding Indian expatriate community has planted eggplant (Solanum melongena), okra (Hibiscus esculentus), horseradish tree (Moringa oleifera) and bilimbi (Averrhoa belimbi). A similar range of food species are cultivated behind the workshops on Topside, although the areas under crops are greater, with some gardeners growing taro, tannia and giant swamp taro, employing the tradi- tional intensive mulching systems of Kiribati and Tuvalu (Thaman 1987a, 1988b). The balance of the "urban vegetation" is composed of many the same species which are occasionally planted as roadside trees or around government and Nauru Phosphate Corporation buildings and parking lots. The remaining area of extensive urban vegetation is the golf course in Aiwo District which is lined with trees, including Hibiscus tiliaceus, Thespesia populnea, but dominated by banyan trees (Ficus spp.). Ruderal Vegetation Extensive areas of highly disturbed ruderal vegetation in settlements, waste places, along roadsides and airstrips, and in areas associated with pre-mining vegetation clearance are found in Nauru. The dominant species in most areas are pioneering grasses, annuals and shrubby weedy species. Common species include; 1) the grasses, Cenchrus echinatus, Chloris inflata, Cynodon dactylon, Dactyloctenium aegyptium, Digitaria spp., Eleusine indica, Eragrostis amabilis, Lepturus repens and Tricholaena rosea; 2) the sedges, Cyperus javanicus, C. rotundus and Fimbristylis cymosa (which, along with Digitaria setigera and Lepturus repens, are probably indigenous); and, 3) the herbaceous species, Ageratum conyzoides, Alysicarpus vaginalis, Amaranthus dubius, A. viridis, Bidens pilosa, Cassia occidentalis, Cleome - rutidosperma, - C. viscosa, - - - Crotalaria goreensis, C. spectabilis, Desmodium tortuosum, Euphorbia spp., Hedyotis-cotjiibosa, Indig$cra- hifiuta, Malvastrum coromandelianum, Passijlora foetida, Phyllanthus amarus, Physalis spp., Portulaca oleracea, Sida rhombifolia, Spermacoce assurgens, Stachytarpheta urticifolia, Synedrella nodiflora, Tridax procumbens and Vemonia cinerea, plus the indigenous species, Phyllanthus societatis and the parasitic Cassytha filiformis. A few tree or tree-like species have become naturalized in dense stands in Nauru. Mangifera indica is dominant in dense forests behind residences in the Buada Lagoon depression; Annona muricata and A. squamosa, as mentioned above, form dense stands on gradually sloping areas of the escarpment; Adenanthera pavonina, Lantana camara var. aculeata, Leucaena leucocephala and Psidium guajava form dense stands or thickets between Buada Lagoon and the decalcination plant on the coastal strip in Aiwo District; and Casuarina equisetifolia and Muntingia calabura have colonized roadside areas and portions of the phosphate-mined area. Of particular interest, is the almost monospecific colonization of the large topsoil stockpile on Topside by the cucurbit, Lu#a cylindrica var. insularum. Phosphate-Mined Lands As a result of almost 80 years of open-cast phosphate mining, some three-quarters of Nauru is under severely-modified disclimax vegetation in various stages of succession. Prior to mining the vegetation is removed by bulldozer and the topsoil removed to expose the phosphate deposits which lie between coral-limestone pinnacles. The extraction of phosphate then causes dramatic changes in local relief, which varies between 4 and 8 m from the top of the pinnacles to the pit bottoms, with about three to four pinnacles occurring within each 100 m2. Because mining is only about 20 per cent efficient, unconsolidated phosphate deposits remain in the pit bottoms and on the saddles and scree slopes between the pinnacles. These deposits (which might be mined at a later date) and the pinnacle surfaces, constitute the main sites for recolonization (Manner a d. 1984, 1985). Although there is widespread evidence that exotics commonly replace indigenous species in highly disturbed habitats, the Nauru study by Manner, Thaman and Hassall (1984, 1985) supports the conclusion of Mueller-Dombois (1975) that indigenous (pioneer) species are often better adapted to edaphically harsh environments, given the cessation of human disturbance. Their study shows a very rapid colonization of mined areas by indigenous ferns and exotic herbs, followed by a fairly rapid replacement by native, primarily coastal strand, species. Early pioneer species include the non-woody exotics, Alysicalpus vaginalis, Cleome rutidospema, Crotalaria goreensis, Emilia sonchifolia, Eragrostis amabilis, Euphorbia cyathophora, E. hirta, E. prostrata, Hedyotis corymbosa, Synedrella nodi- flora, Tricholaena rosea, Tridax procumbens and Vemonia cinerea, plus the indigenous ferns,-Nephrolepk biserrata and Pdypodium scolopendZa. Of these, only the G o ferns species, and Euphorbia hirta, E. prostrata, Tricholaena rosea, Tridax procumbens and Vemonia cinerea remain significant components of the flora in the later stages of succession, usually in open disturbed sites. - - Species entering the succession early and remaining dominants in the 40- to 80- year-old sites include: the trees, Calophyllum inophyllum, Dodonea viscosa, Ficus prolixa, Guettarda speciosa, Morinda citrifolia and Premna serratifolia; the shrubs, Phyllanthus societatis and Scaevola taccada; the grasses and sedges, Lepturus repens, Fimbristylis cymosa and Qperus javanicus; the parasite, Cassytha filiformis; and the diminutive fern, Ophioglossum petiolatum, All are indigenous. Larger exotics found in the later stages of succession in more open habitats include Lantana camara, Psidium guajava and Stachytalpheta urticifolia. The study suggests that the potential natural disclimax vegetation of the open-cast mined plateau will probably be dominated by Calophyllum inophyllum and Guettarda speciosa, with the epiphytic Ficus prolixa dominating the more ecologically severe pinnacle habitats. Morinda citrifolia, Premna serratifolia and the exotics, Lantana camara and Psidium guajava, could become important components of the subcanopy. The exotics, Casuarina equisetifolia (which is native to limestone habitats on other Pacific islands) and Muntingia calabura, both now locally abundant in some mined areas, could enter into the succession as well. As argued by Manner et al. (1985), given no deliberate human intervention, the succession to a disclimax vegetation association capable of sustaining human life will probably take "many thousands of years". It is stressed that it is ironic that Nauru's central plateau, from which Nauruans formerly obtained some of the necessities of life, will be a "topographic jungle" stripped of its natural vegetation, before the next century, in order to provide the phosphate needed to revive phosphate-poor soils to fuel the development of Australia and New Zealand. THE FLORA Like the extremely limited, degraded and displaced vegetation types, the indige- nous terrestrial flora of Nauru exhibits extreme poverty and current numerical domination by exotics. Of a total of 493 species or hybrid cultivars reported to have been present on Nauru, only 59 (12%) are possibly indigenous (Tables 1 and 2). There are no reported endemics, reflecting the lack of habitat diversity and the predominance of ubiquitous, easily-dispersed pantropical or paleotropical coastal species. Two species (Achyranthes canescens and Tarenna sambucina are presumably now extinct, Aidia cochinchinensis possibly now extinct, and half (28) of the remaining 56 species are severely restricted in distribution, endangered or possibly extinct, due to removal and severe habitat modifica- tion or limitation (Table 2). The high number of recent introductions in Nauru reflects its increasing contact with the outside world via its national airline, Air Nauru, increasing urbanization and the total absence of quarantine regulations. - - - - - - -- -- - -- Table 1.

Of these, only 33 are represented by indigenous species. The pteridophytes and gymnosperms are represented by six families, all of which are represented by an indigenous species. The Gymnosperms are represented by only two families, none of which are indigenous. The 145 monocotyledons fall into 18 families, only three of which, Cyperaceae, Pandanaceae and Poaceae, are indigenous. Araceae, Liliaceae and Poaceae are the only families with over ten separate species (26, 34 and 26 respectively). Other monocotyl- edon families represented by five of more species include Arecaceae, Commelinaceae, Cyperaceae, Marantaceae, Orchidaceae and Zingiberaceae. The majority of species from these families are cultivated ornamentals, or in the case of Poaceae, weedy grasses. The dicotyledons are represented by 71 families, 25 of which are possibly indige- nous. Families represented by two or more indigenous species each are Apocynaceae, Boraginaceae, Capparidaceae, Convolvulaceae, Euphorbiaceae, Fabaceae, Malvaceae, Rubiaceae and Verbenaceae (see Part I1 and Appendix I).

Nature of Indigenous Species Of the indigenous species, eight are widespread pantropical or paleotropical pteridophytes, including Psilotum nudum, Polypodium scolopendria, Ophioglossum petiolatum, Pteris tripartita and Nephrolepis spp., with Pyrrosia adnascens, a common epiphyte, also present on Nauru (Table 2). Asplenium nidus, although almost certainly indigenous, was found only as an ornamental in houseyard gardens during the current study. There are no indigenous gymnosperms, although the widespread Cycas circinalis is found in cultivation. Indigenous monocotyledons are restricted to Pandanus tectorius, some cultivars of which are undoubtedly aboriginal introductions, and a small range of sedges and grasses (Cyperaceae and Poaceae), some of which might be aboriginal or recent introductions. TG coconut palm (Cocos nucifcra) is classified as an aboriginal introduction. The grass Stenotaphrum .- --- micranthrum - (reported present - by Fosberg et al. 1987) - is considered to be - --- endangered or now absent. The dicotyledons are comprised almost exclusively of salt-tolerant, widely- dispersed, pantropical coastal species. Of the 42 herbaceous and woody dicotyledons, half (21) are endangered or rare (Table 1). Species such as Heliotropium procumbens, Laportia ruderalis, Triumfetta procumbens, Abutilon asiaticum , Caesalpinia bonduc, Euphorbia chamissonis, Sida fallax, Suriana maritima, Aidia cochinchinensis, Bar- ringtonia asiatica, Cerbera manghas, Erythrina variegata, Hemandia nymphaeifolia, Pisonia grandis, Thespesia populnea and Vitex negundo are represented by only a few remaining individuals, often in houseyard gardens, or by localized relict communities. Prior to widespread disturbance, Nauru would have undoubtedly had more species than it has at present. Comparison with Other Island Floras The extreme poverty of the indigenous flora of Nauru becomes more obvious when compared with estimates of the indigenous floras of island groups which are larger or closer to the Asian plant source region. The estimated number of indigenous species for the following island groups are: Malaya (c. 20,000), Philippines (10,000), Bismarck Archipelago (700), Vanuatu (750), Fiji (more than 1, loo), Tonga (257), Samoa (548) and French Polynesia (600). Only extremely isolated small islands such as Easter Island and the three small atolls of Tokelau, with indigenous floras of 32 and 33 species respec- tively, have poorer floras than Nauru (Good 1947 in Manner 1987, Parham 1971). When taken individually, the floras of Pacific atolls range from as few as three to perhaps 150 indigenous species, compared to some Indian Ocean atolls, nearer to continental areas, which have close to 300 indigenous species (Fosberg 1952). The floristic poverty of Nauru becomes even more pronounced based on a comparison of the frequency occurrence of 142 widespread coastal species in eleven Pacific island groups (see Appendix I1 and Thaman 1992). All of the species considered have the ability to cope successfully in environments characterized by loose shifting sands, wave action, soil-less limestone and volcanic terraces and rock outcrops, high salinity, strong sunlight, strong winds, seaspray and associated physiological drought (Fosberg 1952, 1960) and, in some cases, periodic inundation and waterlogging, all conditions common in Nauru. The island groups analyzed ranged from large, geographically-older high island groups such as Fiji, composed of over 300 islands with a total area of 18,376 km2, to the three small isolated atolls of Tokelau with a total land area of only 12.2 km2. Also included in the comparison were high island groups with diverse habitats, such as Guam, a volcanic island with extensive areas of limestone and an area of 549 km2; Samoa and Hawaii, recent basaltic volcanic island groups, with little or no limestone; Palau, a group - - - - - - - - _ ___-----.- --_p_p---- ~ of some 340 volcanic and uplifted limestone islands, including an atoll, Kayangel, and the raised phosphate island of Angaur, located only 850 km to the east of the Philippines; Tonga, a group of about 150 uplifted limestone and some volcanic islands, with a total area of 697 km2; Niue, an isolated uplifted limestone island, like Nauru, but with an area of 258 km2, and few beaches; and Makatea, an uplifted phosphatic island about the same area as Nauru, and like Nauru, with no protective barrier reefs or coastal lagoons (Thaman 1992). Although these comparisons are strongly biased by the size and geologic age of the islands, their distance from plant source areas and the unavailability of information on other analogous islands such as Banaba (Ocean Island), the poverty of the coastal floras of the two small phosphate islands of Nauru and Makatea (in the Tuamotu Archipelago of French Polynesia) is clearly apparent, both with only 55 of the 142 widespread coastal species each. The Gilberts and Tokelau, both groups of low-lying atolls, have only 74 and 34 species each. All other island groups, including Hawaii and Niue, have at least two-thirds of the 142 species present as indigenous or long-established introductions, an indication of greater habitat diversity and/or less habitat degradation (Thaman 1992). Of interest is that 55 of Nauru's 59 indigenous species are among the 142 widespread coastal or mangrove species listed in Appendix I. As atoll groups, the Gilbert and the Tokelau Islands, have the fewest ferns, although Nauru has the fewest widespread coastal herbs. It could be assumed that the fern, Davallia solida, and widespread herbaceous species, such as Boerhavia, Hedyotis and Portulaca spp. and Sesuvium portalucastrum, were all originally present on Nauru, but eliminated due to widespread destruction of coastal habitats. In terms of coastal grasses and sedges, Nauru, the small atolls of Tokelau, and Makatea have the fewest species, possibly due to the combination of widespread habitat destruction and a relative absence of marsh or wetland environments. The widespread destruction of the areas around Buada Lagoon for cultivation by the Japanese during World War I1 may have destroyed many natural wetland environments. Species which might have been present include the grasses Paspalum distichum and Thuarea involuta. Whether a given sedge species arrived naturally or was introduced deliberately due to its cultural utility is uncertain. Coastal vines and lianas are noticeably fewer on Makatea and Nauru, with only three and eight out of the 14 widespread species. Noticeably absent on Nauru are Abrus precatorius, Entada phaseoloides and Mucuna gigantea. With the exception of the Tokelau Islands (with only three species), Nauru and Makatea have the poorest shrub flora, with only 10 and 11 species respectively, out of a possible 27 species. Similarly, the Tokelaus have only 16 of 62 common coastal tree species, with Nauru and Makatea having only 23 and 21 species respectively. Conspicu- ously absent on Nauru are the shrubs, Allophylus timoriensis, Pemphis acidula, Sophora tomentosa and Wollastonia bijlora; and the trees, Ficus tinctoria, Neisosperma op- positifolia, Pipturus argenteus and Tcrminalia samoensis, most of which are present on the sm2leFelevatd~ phosphate-fich island -of-FaS and t h e cord-limestone island of Satawal in the western Caroline islands (Fosberg and Evans 1969). There are other widespread non-coastal species which might have been present in the past on Nauru, which were present in 1932 (before mining, which ceased in 1966, almost completely destroyed the island's inland vegetation) on the analogous phosphate island of Makatea, which is located much further from the centers of plant diversity than Nauru. These include: the fern, Ophioglossum pendulum; orchids, such as Oberonia and Taeniophyllum spp.; the herb, Procris pedunculata; the vines, A b w precatorius (mentioned above) and Dioscorea bulbijiera (the most widespread of all yam species and present, in many cases probably as an aboriginal introduction, from East Africa to Micronesia and eastern Polynesia)(Stone 1970); and the shrubs and trees, Alyxia sp., Canthium barbatum, Celtis paniculata, Glochidion ramzjlorum, lxora sp., Melochia odorata, Planchonella (Pouteria) sp., and Timonius sp. (Wilder 1934). Tarenna sam- bucina, also present on Makatea, was reported present on Nauru by Burges in 1933, but is now considered to be extinct. Makatea has one presumably endemic species, Euprichardia vuylstekeana, and it might be expected, given the diversity of pre-mining microhabitats and the isolation of Nauru, that there could have been endemic species there also. Interestingly, the one plant that was thought to be possibly endemic on Nauru turned out to be Phyllanthus societatis, "a common plant among coral rocks" on Makatea in 1933 (Wilder 1934). A similar comparison with the relatively undisturbed flora of Henderson Island, a remote raised limestone island with a similar limestone plateau and pinnacle topography, provides further insight into some of the plant species that might have existed in the past on Nauru. Because it was unsuitable for permanent habitation and had no economic phosphate deposits, Henderson has survived successive Polynesian and European impacts, with only five known introduced plant species. Species of widespread genera found on Henderson, but not on Nauru include: the fern, Davallia solida; the herbs, Boerhavia tetrandra, Euphorbia sparmannii, Lepidium bidentatum, Peperomia hendersonensis, Portulaca lutea, Procris peduncu.lata and Sesuvium portalucastrum; the shrubs, Al- lophylus sp., Alyxia sp. , Canthium barbatum and C. odoratum, Glochidion pitcairnense, lxora fragrans, Jasminum didymum, Eugenia reinwardtiana (Eugenia ranyora), Morinda umbellata var. forsteri, Pemphis acidda, Timonius polygamus and Xylosma suaveolens var. haroldii; and the trees, Celtis paniculata var. viridis, Geniostoma hendersonense, Meryta brachypoda, Pittosporum arborescens, Sesbania coccinea and Santalum hender- sonense. Nine species or varieties are presently recognized as endemic, all of which are found in the interior. These are the very areas on Nauru that have been so devastated by phosphate mining, long settlement and devastation and scavenging for food and firewood during the Second World War. Not present on Henderson, but present on Nauru are Calophyllum inophyllum and Barringtonia asiatica (Paulay and Spencer 1989, Fosberg et al. 1983, Fosberg et al. 1989). Nature of Exotic Species Exotic species, which constitute 88 per cent (434 out of a total of 493 reported species) of the flora of Nauru, dominate ruderal, houseyard and urban vegetation. Exotic species include a wide range of ornamentals, weedy species, food plants and a number of other useful species. Ornamentals, which are normally confined to houseyard and village gardens, comprise some 59 per cent (257) of the 434 exotic species. On Nauru, introductions by travellers from Australia, Fiji and other areas with highly developed ornamental gar- dening traditions; the absence of quarantine restrictions; and the almost total breakdown in the subsistence economy, seem to be the main reasons for the disproportionate importance of ornamental plants. Some of these ornamental, of course, have other uses such as living fencing or for the preparation of medicines or garlands. The proportions of the exotic flora composed of weedy species is 18 per cent (80 of 434 species), an indication of both the poverty of the competitive indigenous flora and the highly disturbed nature of the vegetation. Although food plants represent 16 per cent of the exotic flora, due to the harsh environment, limited land area and limited focus on food production in Nauru, many of these species are restricted in numbers or utility and are often represented by experimen- tal attempts to diversify food production or by individual, often immature specimens of a given species. Exotic food plants of particular importance on Nauru include numerous edible pandanus cultivars (Pandanus tectorius), some of which are undoubtedly aboriginal introductions, and the coconut (Cocos nucifera), also an aboriginal introduction. Recent introductions of more localized importance, or of particular importance to contract worker communities on Nauru include: the vegetables, hibiscus spinach (Hibiscus manihot) , Chinese cabbage cultivars (Brassica spp.) , long beans (Vigna sesquipedalis) , amaranthus spinach (Amaranthus spp.) and pumpkin (Cucurbita pepo); the staple root crops, taro (Colocasia esculenta) , tannia (Xanthosoma sagittifolium) , sweet potato (Ipomoea batatas) and cassava (Manihot esculenta); a range of banana and plantain cultivars (Musa cultivars); and the tree crops, lime (Citrus aurantifolia), guava (Psidium guajava), mango (Mangifera indica), soursop (Annona muricata) and the horseradish or drumstick tree (Moringa oleifem), all of which seem to do well in Nauru's harsh environment. Important emergency or pig foods include Polynesian arrowroot (Tacca leontopetaloides) and purslane (Portulaca spp.), both of which are found as naturalised plants in the coastal vegetation of in ruderal sites. Other useful exotic species include kapok (Ceiba pentandra), cotton (Gossypium barbadense), tobacco (Nicotiana tabacum), and bamboo (Bambusa vulgaris), which were all reportedly more abundant in thepast. As suggest&-avove, somelarger ~ ~ e e d ~ x o t i c s , such as Adenanthera pavonina, Annona spp., Casuarina equisetifolia, Lantana camara, Leucaena leucocephala, Mangifera indica, Muntingia calabura and Psidium guajava, some which are classified as ornamentals, food plants or other useful plants, have become naturalized and competitive with the indigenous species in some disturbed and relatively undisturbed sites. ECOLOGICAL AND CULTURAL UTILITY OF EXISTING FLORAS Although highly disturbed, outnumbered and, in some ways, "enriched" by introduced exotics, the vegetation and flora of Nauru still constitute a critical ecological and cultural resource to the people of Nauru. This is particularly true for the indigenous species, virtually all of which had wide cultural utility within the traditional subsistence economy. In terms of the more specific ecological attributes of Nauru's plant resources, the most important functions include the provision of shade and animal and plant habitats, protection from wind, erosion, flood and saltwater incursion, land stabilization, protec- tion from the desiccating effects of salt spray, soil improvement and mulching. In terms of more strictly cultural utility, preliminary analyses indicate 169 purposes or use categories for 39 indigenous species, an average of 4.3 uses per species. There are 434 uses for 354 exotic species, an average of 1.2 uses per species (Table 3). This gives a combined total of 603 uselpurpose categories for 393 species (1.5 uses per species). Twenty (20) indigenous and 80 exotic species had no reported uses. The relative importance of the indigenous flora would undoubtedly be much more pronounced if: 1) a more systematic in-depth survey of the cultural utility of each indigenous species had been conducted; 2) Nauru had not experienced such widespread devastation of its population, traditional economy, traditional education system and its indigenous flora (and associated ethnobotanical knowledge) over the past 100 years; and 3) planted ornamentals, by far the most widespread use of exotic species, were excluded from the analysis of indigenous species.

Moreover, if distinct uses within uselpurpose categories (e.g., tools with distinct functions, different types of fishing equipment, foods or ornamentation for different occasions or purposes, medicines for different ailments, or plants used for specific parts of boats or houses) are counted (see individual uses for each species as detailed in Part 11), the economic and cultural utility of plants becomes even more pronounced. The coconut (Cocos nucifera) palm, for example, has 33 reported uses in Nauru (Table 4), almost undoubtedly a gross underestimate, in light of at least 128 reported uses (many of which are almost ubiquitous) for the coconut palm throughout the Pacific Islands (Thaman 1992). Next in order of importance, are 19 species, all with 5 or more reported uses. These include, in order of importance, Hibiscus tiliaceus, Pandanus tectorius, Scaevola taccada, Morinda citrifolia, Guettarda speciosa, Calophyllum inophyllum, Cordia subcordata, Terminalia catappa, Artocalpus altilis, Thespesia populnea, Tour- nefonia argentea, Premna serratifolia, Triumfetta procumbens, Vitex negundo, Ochrosia elliptica, Cassytha jiliformis, Musa ABB Group, Bambusa vulgaris and Carica papaya. Of these 20 species, only Cocos nucifera, Artocarpus altilis, Musa ABB Group, Bambusa vulgaris and Carica papaya, are aboriginal or recent introductions. The rest are probably indigenous or very early aboriginal introductions (e.g., some authorities suggest that species such as Hibiscus tiliaceus, Morinda citrifolia, Cordia subcordata and Terminalia catappa might have been aboriginal introductions into some Pacific islands because of their cultural utility. Another 13 species, 7 of which are indigenous (Dodonea viscosa, Hemandia nymphaeifolia, Plumeria rubra, Psidium guajava, Erythrina variegata, Bruguiera gymnorhiza, Barringtonia asiatica, Vigna marina, Glerodendrum inerme, Gardenia taitensis, Jasminum sambac, Crinum asiaticum and Hibiscus rosa-sinensis), have at least 3 uses each. Another 22 species have at least two reported uses each (Table 4). There is some usage overlap between categories, such as supplementary and emergency foods, medicinal, magical, ceremonial and body ornamentation plants, or plants used for handicrafts, woodcarving, cordage and clothing. Conversely, the categories could be further broken down to yield an even greater list of uses. Moreover, the list does not include the more strictly ecological functions of coastal plants, such as shade, protection from wind, sand and salt spray, erosion and flood control, coastal reclamation, animal and plant habitats, and soil improvement, all of importance, particularly on an ecological- ly devastated post-mining Nauru. Table 4. Species of particular cultural utility on Nauru based on an analysis of different individual uses listed under each species in Part I1 (Notes: 1) uses do not include a wide range of ecological functions or uses; A = probably an aboriginal introduction; R = recent post-European-contact introduction; all undesignated species are possibly indige- nous).

In terms of specific uses, cultivated ornamentals and food plants are by far the most common. If, however, only indigenous plants are considered, the most widely reported uses are for medicine, body ornamentation, general construction, cultivated ornamentation, boat or canoe building, tools or utensils, handicrafts, scenting coconut oil or perfumery, firewood or fuel, games and toys, hair conditioners, food parcelization, woodcarving, covering or insulating the earthen oven, magic or sorcery, emergency or famine foods, cordage or fibre, clothing, plaited ware and furniture. It must be stressed that the analyses are based on traditional uses, many of which have lapsed or are only employed in emergency, because modern technology has pre- empted them. Modern medicine, clothing, fishing lines, matches, crockery, plastic bags, soap, and emergency food rations (food aid) have, for example, replaced traditional plant-derived products in Nauru. Moreover, many of the current generation, schooled in the modern educational system and living in the cash economy, often know few of the traditional uses of plants, let alone their vernacular names . . . a state which could be referred to as "devegetation of the mind" . . . and which has undoubtedly contributed to the degradation of the indigenous and long-established aboriginal vegetation in Nauru. Of particular note is the importance of traditional food and beverage crops, the abandonment of which, for highly imported foods such as sugar, white rice and flour, cabin biscuits, noodles canned fish, soft drinks, alcohol and tea, has led, as stressed above, to dangerous levels of food dependency and some of the highest, or most rapidly increasing, incidences in the world of vitamin and mineral deficiency and nutrition related diseases. Diseases such as iron-deficiency anemia, vitamin-A-deficiency-induced night blindness, diabetes, cardiovascular disease, hypertension and stroke, gout and hyper- uricemia, some forms of cancer and dental disease, which were rarely encountered in the past are now serious causes of morbidity and mortality in Nauru, and among other Pacific island populations (Speake gt d. 1979; Coyne 1984; Taylor 1983; Zimmet gt d. 1977, 1978; Thaman 1982, 1983, 1988a). CONCLUSION The vegetation and flora of Nauru are among the most impoverished, degTaCd, disturbed and displaced in the Pacific islands. Long habitation, almost a century of open- cast phosphate mining, continuous bombing, destruction and displaceme~t of the people during World War 11, rapid urbanization and the abandonment of agriculture and subsistence activities have arguably produced one of the most severely modified natural and cultural floras on earth. Although both the vegetation and limited indigenous flora of Nauru has been severely degraded and outnumbered by exotic species, many of the native species are still present, unfortunately often in an endangered state. The indigenous flora also still dominates most habitats, including the later stages of the phosphate-mined pit and pinnacle topography of Nauru. Even in ruderal habitats and in houseyard gardens and villages, where they are outnumbered by exotics, indigenous species constitute importan t components. It is argued that, while floristic degradation in Nauru appears to be among the most severe in the Pacific, the current flora still constitutes an important ecological and cultural resource that must be protected as part of the development process, and NOT as an afterthought. Even in the case of Nauru, it may not be too late. PART 11 A COMPILATION OF THE VASCULAR FLORA OF NAURU Part 11, "A Compilation of the Vascular Flora of Nauru", consists of a listing of, and relevant information on, the 493 vascular plant species or distinct cultivars and six widely recognised varieties of common species reported to have been present at some time on Nauru. It begins with Pteridophyta (ferns and fern allies), followed by Gymnosperms and then Angiosperms. Within Angiosperms, Monocotyledons precede Dicotyledons. Under these headings individual families are listed in alphabetical order (e.g. Acanthaceae, Amaranthaceae, Anacardiaceae . . .), with individual species being listed in alphabetical order by genus within each family (e.g. Asystasia gangetica, Barleria cristata, Barleria prionitis, Blechum brownei . . .). KEY Under each speciesfentry the types of information and order of presentation is as follows: 1) Latin or scientific name; 2) common name (s); 3) local vernacular names used by the main ethnic groups in Nauru; 4) synonyms for the Latin or scientific name; 5) antiquity status of the species, i.e., whether it is indigenous to Nauru, an aboriginal introduction or a recent introduction to Nauru; 5) geographical origin of the species; 6) abundance or frequency of occurrence; 7) description of the species; 8) habitat or distribution in Nauru; 9) uses or cultural utility; and 10) an indication of the persons who have recorded or collected a given species, including numbers corresponding to her- barium specimens. This information, its organization and the symbols used under each category are explained below. Latinfscientific Names 1. The first name listed in bold print is what the authors consider to be the currently most widely accepted published Latin binomial for a given species (usually the earliest published name or basionym). All names follow the International Code of Botanical Nomenclature. 2. The Latin names provided in italics after the common and the vernacular names include Latin binomial sEonyms - (sp.) - or older names - no longer -- in -- - use -- for - the species, and, in some cases, incorrect names commonly applied to the species, which are indicated by sensu auct. non. 4. The name (s) or the abbreviation of the name (s) of the authority or authorities (persons responsible for describing and publishing a given species name) are provided after each species name, e.g., (L.) Anders. Family 1. Family names (e.g., POLYPODIACEAE, ACANTHACEAE or RUBIACEAE) are centered in bold capitals immediately before the first species entry in each family. 2 . Where a family is known by two different names or a species placed in either of two families, both are listed (e.g., FABACEAE OR LEGUMINOSAE, POA- CEAE OR GRAMINAE or CLUSIACEAE OR GUTTIFERAE) Common Names 1. English or common names for a species, and other widely-used names, are included in quotation marks, e.g., "coconut", immediately to the far right of the Latin name. Vernacular Names The vernacular names include the Nauruan names and other names used by the dominant ethnic communities of Nauru. These are found on the second line, after the common English names. The letter (B) after a Nauruan name indicates names listed by Burges (1933). All other names were collected by Thaman, Manner and Hassall as part of the current study. N, K, T, C, SI, Philippines and Hindi, are used in parentheses to indicate the Nauruan, Kiribati, Tuvaluan , Chinese (Cantonese) , Solomon Island, Filipino and Hindi names, respectively. The question mark (?) designates unverified or doubtful names. In terms of pronunciation, the Nauruan phonetics are difficult to match with the accepted sounds and orthography of the Latin alphabet. The closet approximations of the correct Nauruan pronunciation of a given name are provided instead of resorhg 30 theuse of strange combinationsuf letters or-special-phonetic symbols. In the cases of other vernacular languages used in Nauru, the 'g' in Tuvaluan is pronounced as if it were like 'ng' as in the word 'sing'; in Kiribati the t, when followed by an i, is pronounced like an s, and when ti falls at the end of a word, the i remains silent, e.g., 'roti' is pronounced as if it were 'rose'. Antiquity Status Antiquity status indicates whether a given species is presumed to be indigenous to Nauru; an aboriginal introduction by Nauruans or other indigenous Pacific Islanders before European contact; or a post-European-contact introduction. In some cases it is suggested that a species may have been successfully introduced prior to European contact, but either not successfully established or brought to extinction before botanical collections or observations of the flora were made. In the case of recent introductions, some species are categorized as to whether they are assumed to be pre- or post-World War I1 introductions. This is based on information received from informants and/or whether a species was reported present before World War I1 by Burges in 1933. The ? indicates that the true status of a species is in doubt (e.g., whether it is really indigenous or an aboriginal introduction). Geographical Origin Geographical origin refers to what seems to be the original natural distribution of a given species before humans began to acts as dispersal agents for plants. In many cases it is difficult to be sure what the original pre-human or pre-European-contact range of a given species was because species introduced either deliberately or accidentally by the Pacific Island colonizers of the islands have often become naturalized and integral components of what now seems to be indigenous vegetation. With respect to terminology, Malesia (sometimes spelled Malayasia) is a biogeo- graphical term referring to an area encompassing insular southeast Asia, the Indonesia, Philippines and the island of New Guinea; Indomalaysia refers to an area encompassing the Indian Ocean and Malesia; Indopacific refers to an area extending from the Indian Ocean to the Pacific Islands; Paleotropics refers to the Old World tropics including tropical Africa, Asia and the tropical Pacific Islands; pantropical indicates that a species is found throughout the Old and New World tropics; and cosmopolitan indicates that a species is found almost worldwide. In some cases (usually in the cases of easily dispersed weedy pioneer species) information is provided on both the assumed original distribution and whether a species is now more widespread (e.g., pantropical). Abundance or Frequency Occurrence - - - -- - - . - -- -- -- - - The estimates of abundance or frequency occurrence or whether a given species is now endangered or extinct are based on in-the field observations by Thaman, Manner and Hassall from 1979 through 1987, plus information included in herbarium vouchers of other collectors. In-the field data included in-depth analysis of all vegetation associations, transects at ten locations around the coastal plain,. transects across the entire island and extensive sampling using 100 m2 quadrats in areas where open-cast phosphate mining had occurred . Species Description Descriptions of individual species (and selection of the most widely accepted scientific names and authorities) were based on the analysis of living plants in Nauru, herbarium specimens and a synthesis of the best existing descriptions in the works listed in the Bibliography. Works of particular value included Fosberg, Sachet and Oliver 1979, 1982, 1987; Haselwood and Motter 1976; Hay, McQuown, Beckett and Beckett 1974; Henderson and Hancock 1989; Henty and Pritchard 1973; Herklots 1972; Macoboy 1969, 1979; Neal 1965; B.E.V. Parham 1972; J.W. Parham 1972; Purseglove 1972, 1974; Rotar 1968; St. John 1973; Smith 1979, 1981, 1985, 1988, 1991; Stemmermann 1981; Stone 1970; Sykes 1970; Whistler 1980, 1983, 1992; Wilder 1934; Wright, Minter and Carter 1984; and Yuncker 1959. Uses and Cultural Utility Ethnobotanical information (including vernacular names) on uses or cultural utility of the individual plant species was obtained through in-depth interviews with elderly person known for their knowledge of the traditional uses of Nauru's plants; other respondents, whenever possible; and from information in available documents and publications. Main informants included Joseph D. Audoa, James Aingimea, Henry Michael Heine, Daphne Fotu, Jacob Gabwinare, Katarina Satto, Kenia Raidinen, Reynold Capelle, Eda Adam and Montiba Star. Collectors and Herbarium Specimens The numbers listed at the end of the information on each species indicate which collectors or observers collected or recorded that species as being present on Nauru; the numbers in parentheses identify the numbers of the herbarium vouchers or specimens collected by each collector (s), e.g., 2, 3(58802), 4(168N), 5(92), 6, 7(27812). The numbers and the collectors/observers are as follows: 1 refers to citations by persons such as Finch prior to 1900, about which there is v e ~ y little information; - - 2 refers to citations by Alan Burges of Sydney University who collected in 1933 and most of whose specimens are lodged at Kew Botanical Gardens, London; 3 refers to citations by F.R. Fosberg of the National Museum of Natural History of the Smithsonian Institution, Washington D.C. in 1980, whose specimens are lodged with the Smi thsonian Institution; 4 refers to Brian Scully of the University of California at Riverside who also collected in 1980 and most of whose specimens are also lodged with the Smith- sonian Institution; 5 and 6 refer R. R. Thaman, H.I. Manner and D.C Hassall of The University of the South Pacific, Suva, Fiji who collected over two 2-week periods in November 1980 and July 1981, respectively, and whose specimens are lodged with the South Pacific Regional Herbarium at The University of the South Pacific, Suva; 7 refers to Thaman and Manner (then with the University of Guam) who collected again in July-August 1987 and whose specimens are also lodged at the South Pacific Regional Herbarium; and, 8 refers to John Swarbrick, of the University of Queensland, Gatton College who collected weedy species on Nauru in June 1988, and whose specimens are lodged in Queensland with duplicates at the South Pacific Regional Herbarium.. When possible, F.R. Fosberg of the Smithsonian Institution examined and verified the identifications of all herbarium specimens. These include some specimens collected in the early 1980s by Dr. Lynn Raulerson of the University of Guam.

MUSACEAE (Banana Family)* *The nomenclature for the genus Musa is confused, with most of the common seedless cultivars or clones being triploid crosses of the fertile species Musa acuminata Colla and M. balbisiana Colla. The Latin binomials M. nana Loureiro, M. sapientum L., and M. paradisiaca L. are commonly used as follows: M. nana for the "dwarf Caven- dish", and M. sapientum for the taller bananas, which are generally eaten ripe, but which are also cooked throughout the Pacific as starchy staples, and M. paradisiaca for the starchier bananas or plantains, which are usually eaten cooked as a staple starch, but occasionally eaten ripe as fruit. The nomenclature most widely used by agronomists is that developed by Simmonds, which classifies all cultivars or clones on the basis of their assumed genetic background, eg. Musa ABB Group would be a triploid cross of one M. acuminata group and two M. balbisiana groups. Both nomenclature systems are presented here to more precisely identify the clones that are currently present in Nauru.

PANDANACEAE (Pandanus Family) * *The nomenclature for the genus Pandanus is, like Musa, confused, with some taxonomists classifying many of the common cultivars and wild clones or species, both edible and non-edible, as forms or varieties of P. tectorius. Other taxonomists consider them distinct species, often listing numerous species or varieties for a given area. For example, P. odoratissirnus L.f. has long been thought to be synonymous with P. tectorius, but is not considered, by many authorities, to occur east of Malaysia. Similar- ly, P. odoratissirnus L.f. var. pyrifonnis Mart. has been used as a synonym for a wild and doubtful variety of P. tectorius, whereas Stone (1970) considers P. fragrans Gaud. to be the common wild species on Guam, and does not consider P. tectorius to be present. Thus, because the fruit of many of the named cultivars or varieties found on Nauru were not collected and identified, the identifications here must be considered provisional, with most named cultivars being grouped under P. tectorius. Other widespread forms, such as P. dubius Spreng., a widespread edible species; and P. spurius Miq. cv. "PUTAT" (syns. P. tectorius Warb. var. laevis Warb. ; P. odoratissirnus L. f. var. laevis (Warb .) Mart., which are widely cultivated for their leaves for use in plated ware, are also possibly present, but not listed here. P. dubius, if present, however, is a very different plant, not likely to be confused with P. tectorius. It has no edible fleshy tissue, but a large globose fruit, 30 to 40 cm in diameter, composed of many drupes, 8 to 18 cm long, each containing a single seed with edible white endosperm. Pandanus tectorius Warb. var. pulposus Warb. epo, epuh (N); te kaina (K); fala (T) syn. P. pyrifomis Gaud. "pandanus" , "screw pine" Indigenous and probably an aboriginal introduction in the case of some cultivars. Pacific Is. Common. Stout, branching tree, up to 5 m or more tall, with numerous aerial roots and thick forking stems; leaves, seldom over 10 cm wide and 1 to 3 m long, spirally-arranged, pointed, with armed or spiny margins and midribs; male inflorescence, fragrant, pendant, with cream-yellow bracts and white spikes; female inflorescence, si=-bu t stnaIkel;n separate trees; f f i i 7 pEii%ppmilCe, m i d ; 2OPt0 30cm-long and 10 to 20 cm wide, with 50 or more wedge-shaped, yellow to red-orange, 1 to 12-celled woody drupes, each about 4 to 8 cm long. Commonly planted on the coastal strip in home gardens and in open areas and in stands on the unmined portions of the plateau (Topside); women were formerly responsible for the care and cultivation of pandanus, although men helped in the initial clearing of land. An important staple to the Nauruans and to the I-Kiribati and Tuvaluans on their home islands. Very important fresh fruit and staple in Nauru and other atoll and Micronesian countries. Named cultivars which still exist on Nauru include enaben (enabun), erabaite (erabwaite), eragadibyaw, eragomogom (eragumugum), inaparabei (inaporabei), inimenoiya, irireiab, and iriribe; other named cultivars, which are reportedly now extinct due to mining, bombing during World War 11, and failure to replant, include eraburabur (eraburbur), eramwimwi, erarapaiwa (erarapeiwa, erarapwiewa), erkibwir, erokwoi, eronubwe, erwuro, inibiterin, and itoidi (etoidi). Some of these cultivars may be P. dubius (see above). Ripe fruit of all cultivars eaten in Nauru as a vitamin-A-rich snack food and also cooked or fermented and put on pandanus mats or leaves in the sun to dry to make a "rich man's" food known as edongo, which is also a traditional food for the sick; leaves, which are commonly soaked in fresh water or boiled, are plaited into mats (itubare), baskets, and other plaited ware, and make the best traditional thatching and roofing; main trunk and stilt roots used in house construction; wood and dried fruit sometimes burned as fuel; thin outside bark of the stilt roots scraped and mixed with coconut juice to cure constipation and poor appetite; I- Kiribati use leaves as cigarette wrappers. According to Wedgewood (1936), during the yearly pandanus harvest (ineded), which usually occurred around August or September, people used to ieave their homes on the coast to stay in temporary bush huts on the pandanus lands in the interior. 2, 3(58760), 5(64), 6, 7(27814?).
