An increasing awareness of declining amphibian populations in the United States requires that the authors develop strategies for evaluating anthropogenic impacts on wetlands and the biota dependent upon these habitats. For example, in the western United States, mining activities may impact a wetland and its biota directly through habitat destruction or run-off of sediments and contaminants generated during mining operations. Amphibians which frequent these transition zones between terrestrial and aquatic habitats may be key biological indicators of a wetland's status. Through a demonstration project located in the mining regions of western Montana, the authors are currently using laboratory and field methods for a wetland evaluation required within a Superfund ecological risk assessment.
