Use shelterwood cutting instead of clearcutting Bat Conservation

A replicated, site comparison study in 2009 of 21 radiotracked bats in jarrah Eucalyptus marginata forest in south-western Australia (Webala et al 2010) found that shelterwood harvested forests had more Gould’s long-eared bat Nyctophilus gouldi and southern forest bat Vespadelus regulus roosts than gap release forests. More Gould’s long-eared bat roosts were in remnant trees in shelterwood forests (10 roosts, 37%) than in gap release forests (one roost, 3%). The remainder of tracked Gould’s long-eared bats roosted in mature forest (eight roosts, 30%) and riparian buffers (eight roosts, 30%). Only one southern forest bat roost was found in shelterwoods, and none in gap release forests. Most southern forest bat roosts were in mature unlogged forest (15 roosts, 71%) and riparian buffers (five roosts, 24%). Shelterwood forest had retention levels of 40–60%. Gap release forest had 95% of the mature overstory removed. Riparian buffers and mature forest areas had been undisturbed for >30 years. Eleven Gould’s long-eared bats and 10 southern forest bats were caught with harp traps at two water holes and radiotracked for 3–8 days in February–March 2009.

Retain riparian buffers in logged areas Bat Conservation

A replicated, site comparison study in 2009 of 21 radiotracked bats in jarrah Eucalyptus marginata forest in south western Australia (Webala et al 2010), found that riparian buffers in logged areas had more roosts of southern forest bats Vespadelus regulus than shelterwood or gap release logged forest, but Gould’s long-eared bats Nyctophilus gouldi had a similar number of roosts in riparian buffers and shelterwood logged forest and fewer roosts in gap release logged forest. More southern forest bat roosts were in riparian buffers (five roosts, 24%) than in shelterwood or gap release logged forest (one roost, 5% in shelterwood; no roosts in gap release). A similar number of Gould’s long-eared bat roosts were in riparian buffers (eight roosts, 30%) and shelterwood logged forest (10 roosts, 37%), but fewer roosts were in gap release logged forest (one roost, 4%). Riparian buffers had been undisturbed for >30 years. Shelterwood forest had retention levels of 40–60%. Gap release forest had 95% of the mature overstory removed. Eleven Gould’s long-eared bats and 10 southern forest bats were caught with harp traps at two water holes and radiotracked for 3–8 days in February–March 2009.
