Provide bat boxes for roosting bats
A replicated study in 2012 in urban parks and forested areas of 11 regions in Navarra, Spain (Alcalde et al 2013) found that 60% of installed bat boxes had signs of occupation by 10 bat species. Out of 405 bat boxes installed, 241 had signs of bat occupation (60%) and bats were found roosting in 107 (26%). In total, 345 individuals of 10 species were recorded: 247 soprano pipistrelles Pipistrellus pygmaeus, 28 common pipistrelles Pipistrellus pipistrellus, 36 Leisler’s bats Nyctalus leisleri, 16 common noctules Nyctalus noctula, seven brown long-eared bats Plecotus auritus, six greater noctules Nyctalus lasiopterus, two Kuhl's pipistrelles Pipistrellus kuhlii, one Daubenton's bat Myotis daubentonii, one whiskered bat Myotis mystacinus and one barbastelle bat Barbastella barbastellus. Approximately 500 bat boxes of seven different models were placed 4–7 m high in forest areas, urban parks and close to rivers. Between September and November 2012, 405 bat boxes were inspected. Bat use of unoccupied boxes was assessed by the presence of guano.
