  1. Create or maintain corridors between habitat patches

    A randomized, replicated study in 1992 of woodland corridors in a national park in Wyoming, USA (Ruefenacht & Knight 1995) found that increased corridor continuity and greater corridor width increased movements of North American deermice Peromyscus maniculatus. Travel along corridors by deermice was greater in continuous corridors than those with gaps and was greater in wide than narrow corridors. However, vegetation characteristics (tree density, ground cover and fallen log density) were more important in determining deermouse movements (results presented as statistical model). Twelve corridors were studied, these being linear stands of aspen Populus tremuloides, surrounded by sagebrush Artemesia sp. Three corridors were wide (20–27 m) with a 10-m gap part-way along, three were wide and continuous, three were narrow (10–16 m) with a 10-m gap and three were narrow and continuous. Deermice were monitored by live-trapping over 10 days, in May–July 1992, at each side of gaps and equivalent spacing in continuous corridors.
