  1. Use selective or reduced impact logging instead of conventional logging

    A replicated, controlled, site comparison study in 2001–2002 of six tropical forest sites in Victoria-Mayaro Forest Reserve, Trinidad (Clarke et al. 2005) found that the composition of bat species differed between selectively logged forest, continuously logged forest and undisturbed forest. Fewer fruit-eating and gleaning animal-eating bat species were captured in selectively logged forest (fruit-eating: 352 bats of nine species; animal-eating: 25 bats of seven species) than in continuously logged forest (fruit-eating: 958 bats of 13 species; animal-eating: 52 bats of eight species). In undisturbed forest, fewer fruit-eating bats (282 bats of 10 species) and more animal-eating bats (71 bats of nine species) were captured than in either type of logged forest. In total, 38 bat species were captured (see original paper for data for individual species). Two sites were surveyed in each of three forest types: selectively logged forest (4–8 selected trees/ha felled in blocks of 150–300 ha), continuously logged forest (trees continuously felled creating an open canopy with fruit plants growing below) and undisturbed forest. At each of six sites, bats were captured at five sampling points using mist nets and harp traps for 6 h from sunset on two nights in 2001–2002.
