This season has been very interesting for the amphibians migrating in the Ryder Lake area! We have conducted 15 evening surveys for adult amphibians since March 6, 2014 and have seen many amphibians both dead and alive. Before May 15, 2014, 283 amphibians were found alive of which 92 were Western Toads and 90 were Red-legged Frogs. A total of 533 amphibians were found dead on the road of which 108 were Western Toads and 214 were Red-legged frogs. Overall, 35% of amphibians found along the survey route have been alive. The table below shows the numbers to date.
