  1. Retain forested corridors in logged areas

    A replicated, site comparison study in 2003–2006 of 53 radio-tracked evening bats Nycticeius humeralis in loblolly pine Pinus taeda plantations in South Carolina, USA (Hein et al 2009) found that forested corridors had more male but fewer female evening bat roosts than logged mid-rotation tree stands. More male but fewer female evening bat roosts were in forested corridors (male: 12 roosts, 39%; female: eight roosts, 18%) than in logged mid-rotation stands (male: six roosts, 19%; female: nine roosts, 21%). The greatest number of roosts were in mature forest (male: 13 roosts, 42%; female: 27 roosts, 61%). Distance to the nearest forested corridor was negatively related to roost site selection in male bats but not females (data reported as statistical model results). The study area (41,365 ha) was intensively managed for pine production. Mid-rotation logged stands were 12–22 years old. Forested corridors (100–200 m wide) consisted of mature pine (>23 years old) and/or mixed hardwood (>50 years old). Bats were caught with mist nets at nine ponds in open habitat from May–August in 2003–2006. Fifty-three adult evening bats (26 males, 27 females) were tracked to 75 day roosts in trees.
