AB In the region of Rýchory (KRNAP - the Krkonoše National Park), effects of roe deer and red deer browsing on the condition and development and natural and artificial regeneration of stands was studied in 2003-2004. Winter and summer browsing were observed in 14 couples of plots (always one with mechanical protection, the second without the protection) and in one control couple in a wintering preserve for red deer. In both years, winter browsing predominated in the region and thus, it is possible to suppose that roe deer was the main browser. As for natural regeneration, silver fir (26% in winter 2003), rowan (36% in winter 2003) and sycamore maple (26% in winter 2004) were the most damaged species. In artificial regeneration, silver fir damage predominated (68% in winter 2003). In the wintering game preserve with the high winter concentration of red deer, damage to all trees exceeded 40% and heavy damage showed also species slightly damaged out of the preserve such as spruce (63%) and beech (75%). Artificial regeneration was damaged more markedly than natural regeneration in all terms of monitoring. The percentage of browsing damage increased with the distance of the additional feeding device.
