Beauty and the beast: how a bat utilizes forests shaped by outbreaks of an insect pest
Abstract The consequences of different management strategies following natural disturbances are a matter of global concern. In former production forests around the Northern Hemisphere, the abandonment of intervention, such as removal of dead wood, after outbreaks of bark beetles has been increasingl...

B. barbastellus foraging activity increased with increasing canopy opening. Maternity colonies were recorded exclusively in trees killed by bark beetles. Bats preferred roost trees with a higher volume (m 3 ha −1 ) of live trees in the surrounding, and trees with on average larger diameters than nearby control trees. Our results revealed that outbreaks of bark beetles result in forest structural attributes that are suitable habitat for B. barbastellus . Salvage logging, i.e., the removal of beetle‐affected trees, generally deteriorates the positive effects of bark‐beetle outbreaks on the foraging and roosting habitat of B. barbastellus . We recommend maintaining snags of large diameter if salvage logging is mandatory. Article in Journal/Newspaper Barbastella barbastellus Wiley Online Library Animal Conservation 21 1 21 30 |
