Provide bat boxes for roosting bats
A replicated study in 2003–2008 in a mixed forest in Poland (Lesiński et al. 2009) found that the occupancy of 70 bat boxes by four bat species increased by more than three times over two years. Bat box occupancy increased from 13% (9 of 70 boxes) in 2005 to 49% (34 of 70 boxes) in 2006 and 2007. Four bat species occupied bat boxes: greater mouse-eared bat Myotis myotis, common noctule Nyctalus noctula, Nathusius’ pipistrelle Pipistrellus nathusii and brown long-eared bat Plecotus auritus. In 2007, bat boxes were colonized first by brown long-eared bats in March and last occupied in October by common noctules. Nathusius’ pipistrelles were the most abundant species that used bat boxes (74% of records from May to September) and were found in the largest clusters in July (14 individuals). In 2003, 70 wooden bat boxes (Stratmann, internal dimensions 25 x 25 x 7 cm) were installed on trees 2.5–3 m above the ground with a southeastern orientation. In 2005 and 2006, bat boxes were checked once in August and from March 2007 to February 2008 boxes were checked monthly.
