Several rodent species can damage forest trees, especially at young tree age in afforestation. Population outbreaks of field voles (Microtus agrestis L.) and bank voles (Myodes glareolus Schreber) in particular can cause losses.
Analyses of long-term time series indicate good synchrony of population abundance in rodent species associated with damage in forestry. This synchrony could be related to the effect of beech (Fagus spec.) mast in the previous year on population growth rates of both species. In shorter time series from Eastern Germany, damage in forestry was mostly associated with autumn abundances of rodents. Environmental factors such as beech mast and snow cover did not explain additional variation in rodent damage to trees.
Beech mast is a good indicator of long-term rodent abundance in Northern German afforestation areas. However, rodent damage to forestry in Central Germany did not seem to depend on environmental parameters other than rodent abundance at large scale. As a result, there is still uncertainty about the link between environmental predictors and rodent damage to forestry, and further experimental work is required to identify suitable environmental drivers and their interplay with other potential factors such as the local predator community. © 2016 Society of Chemical Industry.
几种啮齿动物会对林木造成损害，尤其是在造林初期的幼树阶段。特别是田鼠（Microtus agrestis L.）和林姬鼠（Myodes glareolus Schreber）的种群爆发会导致损失。
对长期时间序列的分析表明，与林业损害相关的啮齿动物物种的种群丰度具有良好的同步性。这种同步性可能与前一年山毛榉（Fagus spec.）结实对这两个物种种群增长率的影响有关。在来自德国东部的较短时间序列中，林业损害主要与啮齿动物秋季的丰度相关。诸如山毛榉结实和积雪等环境因素并不能解释啮齿动物对树木损害的额外变化。
山毛榉结实是德国北部造林地区啮齿动物长期丰度的良好指标。然而，德国中部地区啮齿动物对林业的损害似乎并不取决于大规模啮齿动物丰度以外的环境参数。因此，环境预测因子与啮齿动物对林业损害之间的联系仍存在不确定性，需要进一步开展实验工作来确定合适的环境驱动因素及其与其他潜在因素（如当地捕食者群落）的相互作用。© 2016 化学工业协会。
