Restore wetland Amphibian Conservation

A replicated, site comparison study in 1999 of 11 restored and 29 abandoned wetlands on old mines in southwestern Indiana, USA (Timm & Meretsky 2004) found that species richness was similar at reclaimed and abandoned wetlands. Restored wetlands supported an average of 3–8 species and abandoned wetlands 4–6 species. Two natural wetlands supported eight of nine local species. Breeding was recorded at both wetland types. The emphasis of reclamation was restoring mined lands to the original land use (e.g. forestry and agriculture). However, standards being followed included actions that enhanced reclaimed wetlands by developing the shoreline and establishing ephemeral wetlands. Wetlands included permanent (average 11 ha), semi-permanent (3 ha) and ephemeral sites (<0.3 ha). Call surveys were undertaken over three hours in February–August 2000. Tadpole surveys were conducted in March–August using dip-nets, minnow traps and seines. Twenty-nine abandoned and two natural wetlands were used as comparisons.
