[Dataset:] The Barro Colorado Island Tree Reproduction Dataset

Abstract

The flowering and fruiting status of trees in and around the 50-ha Forest Dynamics Plot (FDP) on Barro Colorado Island, Panama (the southwest corner of the FDP is located at 625773 easting and 1011774 northing in UTM Zone 17). The reproductive status of individuals was monitored in 1995, 1996, 1997, 2005, 2006 and in 2011 - 2015 for 60 species. Data were collected through direct evaluation of reproductive status of individuals from a wide range of sizes. For each focal species, we randomly selected a size-stratified random sample of individuals whose reproductive status was evaluated in the field during the species' flowering or fruiting season. For each individual the reproductive status was evaluated from the ground, using binoculars for the taller crowns. Reproductive status was scored on a five-point scale and is dichotomized here, with zero indicating a sterile tree and 1 indicating a fertile tree with parts of the crown bearing reproductive structures (flowers, fruits or bracts). See Wright et al (2005a) and Visser et al (in press) for more details on these datasets. (Visser
