Amphibian populations as indicators of integrity and recovery from riparian harvesting in a coastal forest

Amphibians are effective and sensitive indicators of forest harvesting effects and riparian forest condition, on an appropriate scale for operational forestry. From spring 1997 to autumn 2000 (about 6 months each year) we studied amphibian populations from before to after forest harvesting at six riparian sites (2 controls, 2 with 30 m reserves, 2 with clearcut to streamside) in coastal forest (CWHdm1). We propose to continue monitoring populations at these sites for two months each autumn for impacts and recovery. The time series will test for recovery of wildlife from forest harvesting, and the effectiveness of riparian reserves in mitigating impacts and promoting recovery. Populations of forest amphibians vary naturally from year to year and this time series will overcome some of the natural variation within the data. In addition, some effects of forest harvesting have long lag times and we need to determine that there are no legacies associated with these lag times.
