The Partnership for Amphibian and Reptile Conservation (http://www.parcplace.org/) presents a unique opportunity for hobbyists and others to work in the company of professional herpetologists. The organization is unique and, in my opinion, far-sighted, in focusing on common as well as rare amphibians and reptiles. Membership is open to all interested persons.
Working groups are established to address species native to each of 6 geographic regions in the USA, as well as in Canada and Mexico, and volunteers are always welcomed. Current initiatives range from monitoring smooth green snake populations to assessing vernal pond habitats.
Frog and salamander enthusiasts can participate in the National Wildlife Federation’s “Project Frogwatch” (www.nwf.org/frogwatchUSA) or the North American Amphibian Monitoring Program (www.pwrc.usgs.gov/naamp). Amphibian deformities, an increasingly common concern, can be reported at www.nbii.gov/portal/server.pt.
State wildlife agencies often support volunteer-based conservation initiatives. Links to the individual agencies (they all have different names) of each state may be found at http://www.fishwildlife.org/ or on the PARK website noted above.
