  1. Restore former mining sites

    A replicated, site comparison study in 2005–2006 of two former mines in jarrah forests in Western Australia, Australia (Craig et al. 2012) found that in restored areas, overall mammal species richness was higher, native mammal species richness was similar, and differences in mammal abundances were mixed compared to unmined sites. Overall mammal species richness was higher in restored sites (2.4 species/site) than in unmined sites (0.4 species/site), but native species richness did not differ (data not reported). In three of four restoration age comparisons, there were more individuals in restored sites than in unmined sites for both house mice Mus musculus (1.7–4.0 vs 0 animals/grid) and western pygmy possum Cercartetus concinnus (0.9–1.0 vs 0.3 animals/grid). In three of four restoration age comparisons, there were fewer individuals in restoration sites than in unmined sites for common brushtailed possums Trichosurus vulpecula (0–0.8 vs 1 animals/grid) and yellow-footed antechinus Altechinus flavipes (0.8–1.8 grid vs 2 animals/grid). Small mammals were surveyed across two mine areas at sites where restoration commenced 4, 8, 12 and 17 years earlier (total six sites for each age class) and in six unmined forest sites. Mammals were trapped using grids with nine pitfall traps, four Elliott traps and Sheffield cage-traps, set along drift-fencing at each site. Traps were set for four nights/season, totalling 1,728 trap nights/treatment.
