Provide bat boxes for roosting bats
A replicated, randomized study in 2009–2010 in 26 managed pine forest sites in northern Arizona, USA (Merings & Chambers 2012) found that almost half the 104 artificial roosts installed across 26 sites were occupied by bats by the second year after installation. Bat occupancy was higher in the second year (49 of 104 roosts at 22 of 26 sites) than the first year (19 of 104 roosts at 13 of 26 sites). Resin roosts were occupied more quickly than wood roosts (resin: within 406 days; wood: 439 days). A total of 47 bats of five species were captured emerging from all artificial roosts. Four artificial roosts were installed/site 5 m above the ground on live ponderosa pine Pinus ponderosa trees. Half were constructed from wood (40 cm wide x 45 cm tall) and half from resin (60 x 60 cm). Roosts were checked every two weeks during May and September in 2009 and 2010. Mist nets or funnel bags were used to capture bats on emergence at dusk.
