What makes a good bat box? How box occupancy depends on box characteristics and landscape-level variables
Bat populations are in steep decline and presently, 16% of all species are classified as "threatened". One main driver identified for this decline is the loss of natural roosting opportunities, caused by the removal of natural habitats. Installation of bat boxes is one solution to compensa...

Bat populations are in steep decline and presently, 16% of all species are classified as "threatened". One main driver identified for this decline is the loss of natural roosting opportunities, caused by the removal of natural habitats. Installation of bat boxes is one solution to compensate for the lack of natural roosting opportunities. Current recommendations for box design emphasize low maintenance costs and are rarely based on empirical evidence. We investigated occupancy of 13634 bat boxes in northern Bavaria, Germany. In our study boxes differed in type, age and mounting height, as well as in maximum community age, i.e. the length of time a group of boxes had been installed in a particular place, the size of box groups and the distance to the next box in the surrounding area, i.e. box isolation.
