Vala M. Ernst Department of Forest Protection and Wildlife Management Faculty of Forestry and Wood Technology Mendel University in Brno Brno Czech Republic ABSTRACT The density of red deer in the area of forest ecosystems disturbed by air pollution in the Krusné hory Mts. - Klásterec nad Ohri Forest District was determined in two model hunting districts Jeleni hora and Cerný potok. To determine the density of red deer two methods were used namely the clearance plot method and a method without the clearance of transects - faecal standing crop. Based on the repeated counting of faecal pellet groups on 16 marked plots No. 1 to 16 in the research area mean values of the estimate of the red deer population density were determined in the Jeleni hora hunting district in 2007 and 2008 using the FSC method viz 24 23 individuals-km-2 95 CI and the CPM method viz 105 88 individuals-km-2 95 CI and in the Cerný potok hunting district using the FSC method viz 8 5 individuals-km-2 95 CI or 77 50 individuals-km-2 95 CI by the CPM method. No statistically significant differences were found out between the density of game and particular groups of similar biotopes. Keywords deer count pellet group red deer The density of game is estimated in forest stands by means of indirect methods most often by counting faecal pellets Putman 1984 . Accurate and precise estimates of abundance are required for the development and management of game populations Marques et al. 2001 . Methods of counting faecal pellets are relatively cheap and quick. However the knowledge of a defecation rate and a period of the faecal pellet persistence in the environment is necessary for the estimate Mayle 1999 . The faecal standing crop and the clearance plot method sometimes referred to as faecal accumulation rate Staines Ratcliffe 1987 Smart et al.
