A Strategy for Saving Amphibians

Submitted by Anonymous (not verified) on

Trout introduced into remote mountain areas of the American West for sport fishing now occupy 95 percent of large mountain lakes. To escape these predators, some amphibians move to shallow, fishless wetlands to live and breed. The problem is that shallow wetlands are particularly vulnerable to climate change. Caught between climate-induced habitat loss and predation from introduced fish, amphibians are at risk of being squeezed out. Removal of introduced fish is a viable approach for improving  amphibian resilience to climate change. A paper written by USGS researchers and collaborators describes development of a technique that combines wetland-specific climate projections with remote sensing data to help land managers assess where amphibians are most vulnerable, and guide plans for possible fish removals from selected lakes.
