  1. Restore wetland

    A small, replicated study in 1999–2004 of three seasonal ponds and 200 potholes created at a forested wetland restoration site on Sears Island, Maine, USA (Vasconcelos & Calhoun 2006) found that wood frogs Rana sylvatica and spotted salamanders Ambystoma maculatum colonized and reproduced in the three ponds and bred in 28% of potholes. Spring peeper Pseudacris crucifer colonized and bred in one pond and American toad Bufo americanus visited but did not breed in two ponds. Reproductive success varied between ponds for wood frogs (0.2–48.4 juveniles/egg mass) and spotted salamanders (1.8–5.4). Metamorphosis of these species was only completed in one pothole before drying. In 1997, two ponds were excavated within the original wetland (350 and 600 m2) and one dry detention basin was converted to a pond (900 m2). Approximately 200 small potholes (0.3–110 m2) were also created. Amphibians were monitored in the three ponds in March–October using enclosure drift-fencing. Pitfall traps were installed in pairs every 10 m either side of fences (9–18 pairs/pond). Eggs were counted within ponds and 50 potholes.
