Salamanders have been proposed as useful biological indicators of environmental change becuse of their abundance and sensitivity to habitat alteration and loss (Wyman and Hawksley-Lescault, 1987; de Maynader and Hunter, 1995). The redback salamander, Plethodon cinereus, may have particular value as an indicator species due to its broad range, high densities, and potential importance to the ecosystem in which it occurs (Wyman, 1998). The use of redback salamanders as a bioindicator species requires longterm techniques for monitoring their populations densities.
