Simulations on a common crane (Grus grus) population model

A simple deterministic model describing the population dynamics of Western European common cranes Crus grus has been developed. Here we present an updated version of the model and test the effects of various natural and man induced events. Low hunting rates (5% of total population or 1000 birds annually) do not significantly reduce the size of the population, due to the density-dependence of survival assumed in the model. High decreases in annual productivity (50%), small decreases in survival (10%), and certain catastrophic events result in the extinction of the population
