Historical ecology can inform restoration site selection: the case of black abalone (<I>Haliotis cracherodii</I>) along California&#39;s Channel Islands

Abstract

* Identifying appropriate ecological conditions for population restoration is important for endangered species such as black abalone (Haliotis cracherodii) in California, but limited information exists regarding restoration locations. * Using a combination of ancient and historical archaeological data and modern commercial fishing records, four optimal locations for restoration based on past relative abundances of black abalone were identified: north-western, north-eastern, and south-central San Miguel Island and western San Nicolas Island. * These locations around California&#39;s Channel Islands have supported dense black abalone populations for at least 10 000 years and may offer optimal environmental conditions to enhance the success of black abalone restoration. * The strategy outlined here illustrates the promise of integrating prehistoric, historical, and modern fishery data to inform restoration of threatened and endangered abalone, oysters, and other shellfish around the world.
