A replicated, controlled, site comparison study in 2010–2012 in 26 savanna and woodland sites in Missouri, USA (Starbuck et al 2015) found that prescribed burning increased occupancy rates of burned sites for one of five bat species. Occupancy rates of the evening bat Nycticeius humeralis significantly increased at burned sites with a greater number of prescribed fires in the past 10 years (data reported as statistical model results). The number of fires did not have a significant effect on the occupancy rates of burned sites for four other bat species (northern long-eared bat Myotis septentrionalis, big brown bat Eptesicus fuscus, eastern red bat Lasiurus borealis, tri-coloured bat Perimyotis subflavus). At each of 26 sites, surveys were carried out at 4–28 sampling points in managed forest and unmanaged mature forest. Managed forests had been burned (with 1–8 fires over 10 years) and thinned to restore savanna or woodland. Bat detectors recorded bat activity at each sampling point for two full consecutive nights during 1–2 years in 2010–2012.
