The most important elements of a successful PVA A fundamental understanding of the species' ecology, including what constitutes suitable habitat, and the ability of the species to disperse between patches of habitat An understanding of the environmental disturbances that directly threaten (or directly threaten through habitat alteration) a species, their probabilities, and impacts on the population (or habitat). This should include the effects of both deterministic threats (eg. timber harvesting, recognising that nothing is completely deterministic), and stochastic threats (eg. hurricanes) An understanding of the response of the species to the threats (eg. density dependence) An assessment of the current state of the population An assessment of the probabilities of future risks An evaluation of the habitat as well as the population itself, and The extent to which the PVA helps managers make decisions.
