In the recent years the damage caused by the game animals to the agricultural crops has increased considerably. An immediate cause of this situation is an expanding population of big game, especially wild boar. This increase is primarily due to the changes in agrocenoses, dominated by large area maize cropping. The crop damage is compensated by hunting associations leasing the specific areas. The aim of this paper was to present the costs of the compensation incurred by the lease-holders of the hunting grounds. A cause - effect relationship between greater game damage and increased harvest of the game animals was demonstrated. The analysis was based on the data provided in the Statistical Yearbooks of the Central Statistical Office for 2000-2013. The study also indicated a problem of a decline in roe deer population, caused by more intense harvest resulting from farmer compensation claims.

One of the conditions of the species continuity is a natural living space (habitat), in which the species achieves its basic needs. Large area of agriculture and forestry monoculture are not conducive to existence of game animals. Permanent devastation of game preserves, windbreaks, liquidation of foraging sites and shelterbelts force the wild animals to feed in the field and forest crops. In modern agrotechnique – the usage of plant protection products deprives the wild species (eg the hare) of forage, on the other hand it causes contamination of food absorbed by animals. Not only does it disorganise the trophic pyramide, but also can cause permanent damage to the organism – environment networks system, which is essential for proper circulation of matter and energy in ecosystems. The aim of the study is to draw attention to the effects of the changes in the biotypes caused by agriculture.
