  1. Restore former mining or energy production sites

    A review of studies investigating the success of habitat restoration following cessation of mining activities in Australia (Cristescu et al. 2012) found that reptile species richness and densities tended to be lower in restored compared to undisturbed areas, and a range of other responses were measured in three studies or less. Restored sites tended to be worse than undisturbed sites when measuring reptile density (lower in restored compared to undisturbed sites in 6 of 9 studies) and species richness (lower in 11 of 12 studies). Evenness (worse in 1 of 1 studies), community composition (worse in 2 of 2 studies), diversity (lower in 1 of 2 studies), body size or condition (similar in 3 of 3 studies), behaviour change (differences found in 1 of 1 studies) and biomass (higher in 1 of 1 study) were also assessed in 1–3 studies each. One study also reported breeding in a restored site. Fourteen studies that measured 33 outcomes for reptiles were included in the review. Restored sites included in the review were formerly bauxite, sand, uranium, coal, gold, manganese or iron mines.

  2. Restore former mining sites

    A review of rehabilitated mine sites in Australia (Cristescu et al. 2012) found that 62% of 13 studies indicated that rehabilitated areas had lower densities and/or species richness of mammals compared to in unmined areas. Seven of 11 studies found that rehabilitated areas had lower mammal species richness than unmined areas, while the other four found rehabilitated and unmined areas had equal or higher mammal species richness. Only two of eight studies found that rehabilitated areas had equal or higher mammal densities compared to unmined areas. Data for individual studies were not reported. Methods combining the use of fresh topsoil with planting seeds and seedlings were most successful for animal recolonization. Studies investigating faunal recolonization of rehabilitated mines in Australia were obtained from the literature, of which 13 of 71 monitored mammals. Studies often compared plots in rehabilitated areas (1–30 plots/study) with plots in unmined areas (1–22/study). Rehabilitated sites were up to 20 years old.
