  1. Use prescribed burning

    A replicated, controlled, site comparison study in 2007–2008 of four mixed forest sites in West Virginia, USA (Johnson et al 2009) found female northern myotis bats Myotis septentrionalis roosting in tree stands treated with prescribed fire and in unburned forest, and roost switching frequency and the distance between roost trees did not differ between burned and unburned forest. Twenty-five roosts were in burned tree stands and 44 in unburned forest, but the difference was not tested for statistical significance. Roost switching frequency and the distance between roost trees did not differ significantly between burned (1–6 days, average 152 m) and unburned forest (1–5 days, 230 m). In April–May 2007 and 2008, three stands (45, 13 and 21 ha) were burned for one day using a strip head fire technique. The remainder of the 1,900 ha forest was left unburned. Bats were captured over streams, pools, trails and service roads at burned and unburned sites using mist nets in May–August 2007 and 2008. In 2007, three female bats were radiotracked to eight roosts. In 2008, 33 female bats were radiotracked to 65 roosts, four of which were used previously in 2007.

What Works in Conservation

What Works in Conservation assesses the research looking at whether interventions are beneficial or not. It is based on summarised evidence in synopses, on topics such as amphibians, bats, biodiversity in European farmland, and control of freshwater invasive species. More are available and in progress.
