In the mountains Hrubý Jeseník was the 18 monitoring plots in the years 2010-2013 conducted tramping of small mammals, inventory damage gnaw the bark of the beech forest plantations and the measured data to investigate the factors influencing the impact of small mammals. Small mammals were then evaluated in terms of dominance, impact on planting and statistically analyzed factors affecting impact. The results show that the dominant group were representatives Arvicolinae (n= 512, 62.4%): Clethrionomys glareolus (n= 306, 37.3%), Microtus agrestis (n= 181, 22.1%), Microtus arvalis (n=23, 2.8%), Microtus subterraneus (n= 2, 0.2%). In terms gnaw the bark of trees to damage most often involved in Microtus agrestis and Microtus arvalis, causing minor damage also Clethrionomys glareolus. Altitude, exposition, composition and character of the herb layer and abundance of voles are significant factors which can affect the impact of small mammals. This information can be useful for forest management, which can reduce the risk of the forest damage occurrence and decrease costs of silvicultural operations.
