Research Projects Supported by CIG

We still know little of the behavior, requirements and population dynamics of giant salamanders. Funds raised by the Cryptobranchid Interest Groups are supporting several research projects. We support radio-tagging of large number of individuals to estimate population size, document the development of individuals and follow their migration patterns. We are also interested in environmental conditions and particularly the water quality of cryptobranchid habitats.
