Abstract
As the number of threatened species increases, and as we understand more about the extent of the problem, the need for effective and efficient means of identifying endangered species and populations becomes more pressing. However, recognizing that a species has a problem is only a first step — a second crucial stage is to be able to assess accurately the situation and to devise an appropriate management plan to aid recovery. Population viability analysis (PVA) is the methodology invoked to address these problems, and can be used in a variety of contexts (e.g. see Gilpin and Soulé, 1986). In this paper we show how different kinds of analysis are appropriate at different stages of devising a conservation management plan, and for different kinds of problem. If PVA is really to play a valuable role in the recovery of many species, close attention must be paid to the assumptions underlying different methods and to the biology of the species being considered (Caro and Durant, in press).
