Agricultural land-use history does not reduce woodland understory herb establishment.

abstract：:(1) Small saplings of Tilia cordata, when planted in deciduous woodlands, are damaged or destroyed by rodents. (2) Experiments with captive animals show that the damage is identical with that caused by bank voles. (3) Bank voles are present at all sites where damage occurs.
