  • I simulated population dynamics of cougars to predict tbe minimum areas and levels of immigration needed to avoid population extinction caused by demo- graphic and environmental stochasticity for a period of 100 years Under mostplausible parameter values, the modelpre- dicted vety low extinction risk in areas as small as 2200 km2, and (in the absence of immigration) increasing risk as area decreased below 2200 km2. If as few as one to four animals per decade could immigrate into a small popula… CONTINUE READING
