Amphibian Egg Mass Monitoring

Monitoring Northern Reg-legged Frogs and Other Amphibians in Partnership with Clean Water Services and Metro

Students surveying
In order to monitor the population of Northern red-legged frogs ( Rana aurora ) as well as other resident amphibians within the RCESC, Clean Water Services and Metro volunteers partner with the Rock Creek Biology and Environmental Studies departments students and faculty to survey yearly for amphibian egg masses. The presence of these species provide indicators of overall ecological health and also helps to estimate numbers and population trends.
