  1. Provide bat boxes for roosting bats

    A replicated study in 1996–1998 in a pine grove Pinus sylvestris in Guadalajara, Central Spain (Paz et al 2000) found bats occupying 8% of boxes and bat droppings in 2% of boxes checked. Bat species occupying the boxes were brown long-eared bats Plecotus auritus (176 bats) and common pipistrelles Pipistrellus pipistrellus (2 bats). Larger bat boxes were occupied more (9%) than smaller boxes (7%). The height and orientation of boxes did not have a significant effect on bat occupation. The larger boxes were based on the “Richter II” model (external dimensions: 40 cm height x 25 cm length x 22 cm width, internal capacity: 3,600 cm3). The smaller boxes were based on the “Stratmann FS 1” model (external dimensions: 40 cm height x 30 cm length x 11 cm width, internal capacity: 2,000 cm3). During April 1996, 203 bat boxes were installed on trees (108 large, 95 small) at heights of 2.9–5.5 m in rows spaced 50 m apart with an average density of 4 boxes/ha. Sixteen surveys with 2,134 total box visits were carried out in August–October 1996 and March–October 1997 and 1998.
