Traces of gnawing on soft bark of twigs and small stems of young trees, reaching the wood, but sometimes only slight damage to the wood; roundish feeding pattern or girdling; feeding also from roots of young plants and trees – mostly only main roots or parts of them remaining; gnawing on tender twigs, buds and shoots, especially in winter below the protecting snow coverage; feeding from seeds in the forest, which are collected in repositories; feeding from seedlings of forest trees.

Damage by rodents may considerably reduce natural regeneration in forests (seeds and seedlings); decline of single trees up to whole afforestations; growth reduction and disposition to various pathogens; sometimes growth anomalies and abnormal shoot production (damage to buds)
Curative measures Noxious baits, best concentrated in bait-stations, mouse traps of various kind; mawing and removal of grass to make the establishment of populations unattractive; mechanical or chemical removal of weeds in and around afforestations (see official register of Plant Protection).
