- The paper synthesizes the knowledge on the impact of silvicultural treatments on bat populations. Forest management affects stand structure and composition, and silvicultural treatments exert both positive or negative impact on the activity of individual bat species. Studies published on the issue suggest that forest management may prove useful for the conservation of bat populations, especially in areas that are important to bats. Harvesting system influences spatial and age patterns as well as the share of open woodland areas in forests, which are used by majority of bat species. In particular, polycyclic harvesting systems result in a mosaic of open midforest areas of various size such as clearcuts, group shelterwood cuts and gaps in forest stands, which are very attractive for aging habitats to bats. Common noctules and parti−coloured bats prefer to hunt by flying at high speeds and altitudes above open midforest areas such as clearcuts and group shelterwood cuts. Serotine bats and Nathusius' pipistrelles use smaller gaps and stands treated with shelterwood cuts. Barbastellas and Bechstein's bats prefer more cluttered foraging habitats in dense vegetation and canopy, while long−eared bats fly slower and glean their prey from plants. Selection cutting and irregular group shelterwood methods, which have the fewest cutting constraints, contribute most significantly to creating a mosaic of diversely structured stands and open midforest areas. Forest stands managed with such harvesting systems are the most preferred foraging sites for the largest number of ecomorphological groups of bats. The thinning of trees at younger age reduces density, thus opening up new foraging sites or providing access to such sites to bats, which fly fast, but are less manoeuvre (e.g. common noctules). The loss of roosting habitats for maternity colonies due to tree cutting or microclimate changes in forest stands is the greatest threat from the forest management. Silvicultural treatments affect the structure of forest stands and, in consequence, bat populations. Sustainable forest management may be useful for bat conservation. Forest stands with diverse structure as well a mosaic of variously−sized midforest areas provide the best foraging and mating conditions for the highest number of bat species.
