Provide bat boxes for roosting bats Bat Conservation

A replicated, controlled study in 2011–2012 in ancient, mixed deciduous woodland in Buckinghamshire, UK (Dodds & Bilston 2013) found that brown long-eared bats Plecotus auritus and Natterer’s bats Myotis nattereri preferred three of five bat box designs.  Three Schwegler designs were occupied most by brown long-eared and Natterer’s bats: 1FS (33% of total occupations), 2FN (29%), and 2F (27%). Schwegler 1FF boxes were rarely used (11%), and wooden Apex boxes were not used at all. Groups of five Schwegler woodcrete boxes (2F: 33 x 16 cm; 2FN: 36 x 16 cm; 1FS: 44 x 28 cm; 1FF: 43 x 27 cm) and one wooden Apex box (40 x 12 cm) were erected around 13 trees in March 2011. Groups of bat boxes were evenly spaced along a transect line of 300 m through the woodland. Bat boxes were checked monthly in May–October 2011 and 2012.
