摘要: The wild boar is a native animal species of the Czech Republic that has significantly increased its population density in recent years. Objective methods estimation are required to inform intensity regulation needed for sustainable management boar. Population and abundance problematic comparison those other ungulates, only widely used method control intensive hunting. purpose this study was test if faecal pellet group (FPG) counting reliable censusing forest environment. boars evaluated an area 22.56 km2, circumscribed by both natural man-made barriers restrict migration. As it essential proper application FPG count methods, separate trial carried out determine daily defecation rate boars. distribution faeces different types habitat environment tested. period accumulation fell within hunting season, result biased fact calculation includes FPGs produced animals removed from through during winter. average adults piglets 4.29 5.82, respectively. corrected (without shot animals) estimated at time census 6.08 individuals (ind.)/km2. We have confirmed conducted winter applicable on forested area.
