Population Viability Analysis (PVA. A PVA can be very helpful in assessing the demographic impact of threats and problems as well as conservation actions. They can be used to quantify assumptions and their impact on the future of the populations concerned. If a PVA is to be used, it should be obtained from a relevant scientific source and ideally developed for the species/population prior to the action-planning workshop. The simplest PVA sufficient for the problem in question should be used. A PVA can also highlight knowledge gaps about the population parameters or species biology that can be further researched/monitored.
