  1. Use prescribed burning

    A replicated, site comparison study in 2009–2011 in managed upland forest in Kentucky, USA (Johnson et al 2019) found that home ranges of female Rafinesque’s big-eared bats Corynorhinus rafinesquii were similar distances from burned and unburned forest, whereas the home ranges of male bats were closer to unburned forest. Home ranges of female bats (including non-reproductive, pregnant, lactating, and post-lactating females) were not located significantly closer to burned forest than unburned forest (data reported as statistical model results). Home ranges of male bats were further from burned forest than unburned forest. Prescribed burns of low-moderate intensity were carried out each spring within an area of deciduous, coniferous, and mixed forest. Burned areas were an average of 252 ha. Forty-one adult Rafinesque’s big-eared bats (33 females, eight males) from four colonies were captured in mist nets and radio-tagged. Each bat was tracked to an average of 38 locations over 2–5 nights in May–September 2009–2011.
