Exclude domestic animals or wild hogs by fencing
A replicated, site comparison study in 2002–2003 of streams within pasture in southwestern Georgia, USA (Muenz et al. 2006) found that excluding cattle did not result in increased amphibian species richness or abundance along stream banks, but did result in significantly higher numbers of in-stream larvae. There was no significant difference in amphibian species richness between buffered and unbuffered streams, although species richness tended to be higher where cattle were excluded. Abundance of adult salamanders and treefrogs Hyla spp. did not differ between sites. At three sites cattle grazed stream banks and at two other sites cattle had been excluded by fencing for over 25 years. Amphibians were monitored by walking a transect (100 x 4 m) along one side of each stream from March 2002 to March 2003. Bimonthly surveys under natural and artificial cover objects (30 tiles/site) and monthly surveys using tree pipes (10/site) and stream bottom samplers were undertaken.
