摘要

Regeneration of natural forest structures and dead wood has a key role in the long-term maintenance of biodiversity in most parts of the boreal zone. In order to obtain benchmarks for practical dead wood management rapidly, we utilised unintended historical experiments in land use by studying the recovery of forests surrounding abandoned villages along 2.5-km transects in NW Russia. The signs of past human forest use declined as a function of distance from villages. We found that the closest forests were 130 yr old or younger and contained very few elements typical of natural forests. Forests at a distance of between 1 and 1.5 km were older than 150 yr but showed marks of selective cuttings and had a less complete continuum of dead wood than forests that were 2-2.5 km from the villages. The most remote stands, which were generally older than 200 yr, predominantly had no signs of past forest use and had the most diverse dead wood composition. Our study shows that full recovery of the dead wood continuum in middle boreal forests is a slow process and also that less intensive past forest use can have a significant effect on the dead wood continuum.
