Create ponds for amphibians
A replicated, site comparison study in 1996–2002 of 10 constructed ponds within a wetland restoration area in North Carolina, USA (Petranka, Kennedy & Murray 2003) found that created ponds were rapidly colonized by amphibians and contained significantly more breeding species than natural ponds (4 vs 3/pond; see also Petranka, Murray & Kennedy 2003, Petranka & Holbrook 2006). Overall, seven species bred in created ponds within the first year and 10 species in 2002. Species richness reached equilibrium within two years. A total of 10 species bred in natural ponds. One species was only recorded in one natural pond. Six species occupied constructed ponds significantly more frequently than natural ponds (33–99 vs 0–78%). Occupancy of pond types by the other four species did not differ significantly (0–99 vs 9–93%). Ten ponds were created in 1995–1996 (average 480 m2). Restoration in 1996–2002 also included restoring original channels, filling ditches, removing fill and planting native trees. Ten natural ponds were surveyed for comparison. Ponds were surveyed using dip-netting and open-bottomed samplers each 1–3 weeks in January-August each year.
