Evaluating the Health of Our National Wildlife Refuges : Amphibian Abnormalities
1 - 2
Reason for Concern
The Service helps conserve habitat through the National Wildlife Refuge System (Refuges), the world’s largest and most diverse collection of lands set aside specifically for the conservation of wildlife. To ensure the health of this habitat, Service environmental contaminant specialists monitor the effects of contamination on fish and wildlife. Many amphibian species are sensitive to a variety of environmental stresses and may be good early indicators of the health of their environment. Therefore, the Service is interested in determining whether abnormal frogs occur on Refuges, and if so, investigating potential causes.
