A new method of wild boar, Sus scrofa (Linnaeus), census tentatively called the “Carpathian technique” was tested in Poland during February and March 2000–2004. This method is based on the relationship between absolute population density (N/1000 ha of forest) and a snow track index (T/Km x day-1). The absolute density of wild boar was estimated on the basis of 177 sampling plots, of 400–500 ha. Snow tracks of wild boar were counted along line transects with a total length of 4,442 km. High correlation (r=0.59 - 0.88) between the density of tracks counted along line transects (T/Km*day-1) and species density calculated from sampling plots (N/1000 ha) has been obtained. This relationship was employed to calculate the density of wild boar in 58 Forest Districts and 2 National Parks. In forest districts and National Parks, the lowest density of wild boar i.e. 0.49 animals/1000 ha of forest was recorded in Bieszczady Mountains, and the highest density (120.7 individuals/1000 ha) was recorded in the Myślibórz Forest District. Over respective regions (that includes several forest districts and the sampled National Parks), density of wild boar was the lowest in Carpathian and Sudety Mountains, near density = 4.06 animals/1000 ha, while in north-eastern and southern lowland regions density varied from 9.0 to 19.71 animals/1000 ha, respectively. The highest density (36.7 animals/1000 ha) was recorded in north-western lowland forest region.
