Provide bat boxes for roosting bats Bat Conservation

A replicated, site comparison study in 2009–2010 in five pasture and tropical forest fragments in Costa Rica (Reid et al. 2013) found that 26 of 48 bat boxes were used by at least five bat species, although only three boxes were colonised as permanent day roosts. Overall, 54% of bat boxes were occupied by bats. More bat boxes were occupied in forest fragments (17 of 18, 94%) than in pasture (12 of 30, 40%). At each of five sites, six bat boxes were installed in pasture on wooden or steel posts or on 4 m long tree limbs (replanted and allowed to grow for three months), and three to six bat boxes were installed on trees in adjacent forest fragments. Bat boxes were constructed from wood and concrete (interior dimensions: 40 x 40 x 60 cm) and mounted 2–3 m above the ground. Visual checks were carried out twice/month in 2009 and 2010, and motion-activated infrared video cameras were installed.
