Conservation measures for the Eurasian otter in the Czech Republic

A4 Population viability analysis

Population viability analysis (PVA) is a species-specific method of risk assessment frequently used in conservation biology. It is traditionally defined as a process that determines the probability that a population will go extinct within a given number of years. A basic model, predicting the probability of extinction of the Czech otter population, has been already prepared within the previous ALKA Wildlife research project and will be now updated and improved based on newly acquired data. The more precise input data are, the more reliable outcomes (scenarios) the model produces.
