Population densities of wild boars (Sus scrofa) and wolves (Canis lupus) for the 16 years between 1980 and 1995 in the Bieszczady Mountains, south-eastern Poland, were compared to evaluate possible effects of wolf predation on the dynamics of wild boar populations. The population trends of wolves (measured by the level of their harvest) and wild boars showed opposite trends with a significant negative relationship (r^2=0.611, p<0.001).
