Conservation Evidence: Evidence Data

Collected Evidence: Collected Evidence: Protect habitats for amphibians One replicated, site comparison study in the UK found that populations of natterjack toads were better protected at sites with a statutory level of habitat protection than those outside protected areas. One before-and-after study in the UK found that a common frog population increased but common toads decreased following the protection of a pond during development.

One replicated, site comparison study in the USA found that retaining buffers along ridge tops within harvested forest increased Red Hills salamander abundance, body condition and genetic diversity. One replicated, controlled study in the USA found that retaining unmown buffers around ponds had mixed effects on tadpole survival and mass depending on species and site. One replicated study in the USA found that 30 m buffer zones around wetlands were not sufficient to protect marbled salamanders.
