  1. Provide bat boxes for roosting bats

    A replicated, controlled study in 1999–2000 in Fort Valley Experimental Forest, Arizona, USA (Chambers et al 2002) found that bats used 17 of 20 artificial roosts (eight resin and nine wood) placed on snags in thinned (10 roosts) and unthinned (eight roosts) pine stands. Bats did not roost more often in natural control snags (five roosts). There was no difference in the use of two artificial bat roost designs (resin and wood, both 60 x 60 cm cylindrical designs). Resin roosts were made from polyester moulds shaped and painted to resemble exfoliating bark. Wood roosts were made from treated hardboard. Five resin and five wood artificial roosts were placed 2–4 m above the ground on snags in three unharvested stands and three thinned stands with a natural control roost on a snag at least 75 m away from each artificial roost. Nets below roosts were checked for guano 3–4 times in July–August in 1999 and 2000.
