Create ponds for amphibians
A replicated before-and-after study in 1996–1997 of 37 created ponds in forest, farmland, grassland and residential areas in Latah County, Idaho, USA (Monello & Wright 1999) found that up to seven species of amphibians were present. Three species were present within 24–33 of the ponds and four within 3–4 ponds. The proportion of ponds used for breeding varied with species (Pacific tree frog Hyla regilla: 54%; Columbia spotted frog Rana luteiventris: 35%; eastern long-toed salamander Ambystomam acrodactylum columbianum: 62%; American bullfrog Rana catesbeiana: 5%; roughskin newt Taricha granulosa: 8%). Western toad Bufo boreas and blotched tiger salamander Ambystoma tigrinum melanostictum reproduced in a single pond. Ponds (25–860 m2) that had been created by excavation and damming areas of high water runoff were surveyed 12–20 times in March-August. Surveys comprised visual encounter searches of the shore, egg searches, dip-netting and call surveys at four locations around ponds. Four to eight funnel or minnow traps were also set for a minimum of 14 days in February-April.
