Abstract

The analysis of changes in the density of the red fox population over a period of several years showed a considerable stability of this population.The average density in winter was about 0.43 animal/km2. A high reduction of foxes in winter (52%) seems to be mainly a result of hunting. In the population of adult foxes females prevailed. Litter size and the survival of cubs till the hunting season depended on the availability of small mammals (mainly rodents). The expected mean life span at birth (E0) was low (0.84-0.91 year) as compared to populations subjected to lower hunting pressure. Only one fourth of foxes born survived to the age of 12 months.
