  1. Create ponds for amphibians

    In a continuation of a study in North Carolina, USA (Petranka, Kennedy & Murray 2003), a replicated, site comparison study (Petranka, Murray & Kennedy 2003) found that breeding populations of wood frogs Rana sylvatica and spotted salamanders Ambystoma maculatum increased from 1997–1998 following pond construction (see also (Petranka & Holbrook 2006). Numbers then decreased to pre-construction levels in 2002, due to drought and ranavirus. Wood frogs reproduced within 71% and spotted salamanders within 59% of created ponds in the first year. From 1996–2002 juvenile productivity was significantly higher in created than natural ponds for spotted salamanders (47 vs 24%), but similar for wood frogs (34 vs 26%). Juvenile productivity and survival tended to decrease in both types of ponds over time. Numbers of eggs tended to be higher in ponds located where breeding sites existed prior to construction. Egg mass counts were undertaken every 1–3 weeks during the breeding season in 1996–2002.
