Retain forested corridors in logged areas Bat Conservation

A replicated, paired sites study in 2004–2005 in 32 pairs of forested corridors and logged loblolly pine Pinus taeda stands in South Carolina, USA (Hein et al. 2009) found that forested corridor edges had higher overall bat activity than corridor interiors or adjacent logged tree stands. Higher bat activity was recorded along forested corridor edges (54 bat passes/detector/night) than in corridor interiors (7 bat passes/detector/night) or in adjacent logged stands (12 bat passes/detector/night). Six bat species were recorded in total (see original paper for data for individual species). The study area (41,365 ha) was intensively managed for pine production. Thirty-two forested corridors (100–200 m wide) were paired with adjacent logged stands of a similar age. At each of 32 pairs of sites, bat activity was simultaneously recorded with five bat detectors (one on each corridor edge, one in the corridor interior, and two in adjacent logged stands) from two full consecutive nights in June–August 2004 or 2005.
