  1. Exclude domestic animals or wild hogs by fencing

    A replicated, site comparison study in 1998–1999 of streams in pasture in Pennsylvania, USA (Homyack & Giuliano 2002) found that excluding livestock from stream banks did not increase amphibian species richness or abundance overall, but did increase tadpole numbers. There was no significant difference in overall species richness, abundance or biomass, or in the abundance of salamanders, bullfrogs Rana catesbeiana or wood frog Rana sylvatica between fenced and unfenced streams. However, tadpole captures were higher in fenced compared to unfenced areas (20 vs 6). In comparison, captures were higher in unfenced compared to fenced areas for green frogs Rana clamitans (8 vs 5/site) and American toads Bufo americanus (2.4 vs 1.5). Ten grazed and 10 recently fenced (1–2 yrs) streams were selected over 20 farms. Sites were 100m long by 10–15 m wide on both banks. Monitoring was undertaken using two drift-fences per site. Each fence had a pitfall trap, side-flap pail-trap and funnel trap that were checked 3–4 times/week in April–July.
