The field vole (Microtus agrestis) is commonly the most frequent and most harmful species of Microtine during mass outbreaks in Austrian forests. In the last two years a 0.7 ha large plantation with valuable deciduous tree species was heavily attacked by field voles, causing severe damage to ash (Fraxinus excelsior) and sycamore (Acer pseudoplatanus), while sparing sweet cherry (Prunus avium). It was found as reason for the outbreak that swath was left after mowing the ground vegetation. As damages by voles are often detected too late, sample catching for prognosis is recommended to allow for effective measures at the beginning of outbreaks. The dry, hot summer of 2003, ensuring the best possible conditions for the development of the voles requires a heightened state of alertness as severe attacks are to be expected.
