  1. Retain residual tree patches in logged areas

    A replicated, site comparison study in 2000 of six sites in logged forest in central British Columbia, Canada (Swystun et al 2001) found that the edges of residual tree patches had similar bat activity to clearcut forest edges. Overall bat activity along residual tree patch edges (49 total bat passes) did not differ significantly to that along clearcut forest edges (110 bat passes). Six residual tree patches (0.5–2 ha) were sampled in six clearcut blocks (105–180 ha, <5 years old) in logged forest (dominated by lodgepole pine Pinus contorta). At each of six sites, bat activity was recorded with bat detectors simultaneously along residual tree patch edges and clearcut edges for one night in July–August 2000.
