Situation of Wild boar populations in western Poland

Abstract

On the base of the investigations carried out during ten years, the population of Wild boar inhabiting 8,000 ha forest area in western Poland has been characterised. Such parameters as reproductive ratio, mortality and longevity are described. The reproductivity ratio of population depends on the high degree on the age structure of females. This population consisted of 49% of piglets, 35% 1-2 years old animals and only 16% older than 2 years.Total productivity of population reached about 190% of number of sows. The mortality ratio of piglets during the first 3-5 months of life was about 27% of number of young born. The average length of life was estimated to 1.5year
