Provide bat boxes for roosting bats Bat Conservation

A replicated study in 1998–2001 of three forest stands in a mixed forest in Poland (Ciechanowski 2005) found that an average of four of 102 bat boxes (4%) were occupied by bats, and boxes became occupied more quickly in pine tree stands than deciduous stands. Bat species roosting in bat boxes were Nathusius’ pipistrelles Pipistrellus nathusii, or brown long-eared bats Plecotus auritus roosting individually or in groups. Bat boxes were occupied within two months in the pine stand, but within 13 months or more in beech and oak-beech stands. In 1998, 34 wooden bat boxes (Stratmann design, 40 x 13 x 4 cm) were installed in each of three stands (pine Pinus sylvestris, beech Fagus sylvatica and oak-beech Fagus sylvatica-Quercus robur). At all three stands, bat boxes were checked every 10 days in July–September 1998–1999, every two weeks in April–June 1999 and for two days in August 2001. The pine forest stand was also checked twice in July–August 2000.
