The eastern red-backed salamander and its cousin, the Shenandoah salamander, are by no means formidable creatures, at least in the conventional sense. The physical attributes and habits of these woodland salamanders (genus Plethodon) however, makes them particularly vulnerable to environmental threats, and thus an early warning system for forest ecosystem health and for animals higher in the food chain, including man.
Recent international declines and even extinctions of amphibian populations, including salamanders, might be cause for concern, and a global effort began in 1991 to investigate the problem. The Declining Amphibian Populations Task Force (DAPTF) was established that year because of the declines and because of a lack of information and data on the dynamics of amphibian populations.
