Create ponds for amphibians
A replicated before-and-after study in 1992–1994 of 22 constructed ponds within two clearcut areas of the Monongahela National Forest, West Virginia, USA (Barry, Pauley & Maerz 2008) found that 11 ponds in the first year and 14 in the second were used by breeding amphibians. Of the 14 ponds used, 43% were used by more than one species for breeding. Ponds supporting three species were significantly deeper and tended to have higher nitrate concentrations than those supporting fewer. Species included American toad Bufo americanus, wood frog Rana sylvatica, mountain chorus frog Pseudacris brachyphona and Cope's grey tree frog Hyla chrysoscelis. Allegheny mountain dusky salamander Desmognathus ochrophaeus and spring salamander Gyrinophilus porphyriticus were present but not breeding. Ponds up to 28 m2 and 37 cm deep were constructed randomly along an abandoned logging road six months after timber harvest. Monitoring was undertaken monthly in April-September 1993–1994. Dip-netting and funnel traps were used along drift-fences around each pond.
