Amphibians are widely regarded as indicators of ecosystem health. Relatively few native species have been identified in the San Juan Islands, and their status and distribution are uncertain. Of special interest are the woodland salamanders Ambystoma gracilis, restricted to one drainage on Lopez Island, and Ambystoma macrodactylis, restricted to one drainage on Orcas Island. The Western Toad is known historically from several islands, but may now be locally extinct. Kwiaht is investigating all reports of these animals, as well as monitoring the expanding range of invasive East Coast bullfrogs (Rana catesbeiana).
