Population models are useful tools to develop action plans and allow an estimation of the influence of different parameters on population development. They allow the estimation of population trends and the assessment of management measurements. For the European wildcat (_Felis silvestris_) a population model was calculated with VORTES (Lacy 1993) to test the influence of various parameters on survival of the population and to estimate the framework of a possible supplementation. Available data confirm a medium-term survival of the Austrian wildcat population. The main influencing factors are juvenile mortality and reproduction rate. In order to achieve a stable population on a long term perspective, at least 100 individuals are necessary. If such a population is to be established by release from an annually available pool of 10 individuals, it may take up to 8 years to form a stable, sustainable wildcat population in Austria. |
