This is part of a two-volume reference work on rare and endangered biota of Florida. Each volume is arranged in order of species status: extinct, extirpated, endangered, threatened, rare and special concern. The account of each species contains data categories of taxonomy, description, population size and trend, history and range of distribution, geographic status, habitat requirements and vulnerability of species and habitat. The review of the environmental situation of the species includes causes of threat, responses to habitat modification, demographic characteristics, key behaviours and conservation measures that have been taken and those proposed for the future. Tables list species currently on the FCREPA list with their status. Also included arre the current designations of status by the US Fish and Wildlife Service and the Florida Game and Fresh Water Fish Commission. Of the 39 fishes listed in this volume, none have become extinct since the publication of the original edition. However, the Okaloosa darter is still losing ground to the introduced brown darter. Only one native freshwater fish has been added to the list - the Southern starhead topminnow, but much new information on the reappearing species has been gathered from survey works or directed studies. Volume I focuses on mammals.
