Recommendations for Monitoring Amphibians at Multiple Spatial Scales

Karen M. Dvornich and Kelly R. McAllister

The Washington Gap Analysis Project has characterized the entire state in terms of both ecological zones and predominant vegetative cover types. We recommend that this habitat characterization be used to develop a sampling scheme for the long-term monitoring of herp populations on a state and regional scale. The combination of ecological zone and vegetative cover type produces polygons of similar character. A stratified random sampling scheme could be used to select polygons in which monitoring sites and protocols could be established. Selected polygons could be sampled according to a design that takes advantage of access considerations as well as the need to sample microhabitats that are representative of those present within the polygon.
