Population estimates of Appalachian salamanders.

Identical observations, conducted 1-4 times per year for 15-20 years at two locations in the southern Appalachians, have yielded quantitative data on populations of six species of salamanders. Although the numbers have fluctuated for various reasons, there has been no trend in the numbers of any of the species. The "world-wide decline of amphibian populations" has not occurred in the two localities studied. Please refer to the methodological summary near each graph on the following web page, http://www.unc.edu/~rhwiley/salamandertrends/ The number of salamanders observed in a 1.5 hour search from the creek southward up the slopes 150 m (average of two trips in September each year).
