Natural and anthropogenic factors in dynamics of settling of the Vyatka river basin by wild boar in Holocene

Due to changes in climate and in plant cover the dynamics of settling of the Vyatka River basin by wild boar (Sus scrofa L.) was studied. The data on the content of the bone material in sediments on the sites of hunters stays in Mesolithic-Neolithic-Bronze and Iron epochs are given. Current materials on the ecology of wild boar show that its vital functions in natural ecosystems always depend on oak (Guercus robur L.) distribution. Anthropogenic transformation of landscapes favours its survival in taiga ecosystems. With the growing bioclimatic trend and moving of borders of broad-leaved forests to the north the increase of wild boar numbers is expected.
