Fraser Valley Conservancy worked with cement manufacturer Lafarge to create an innovative concrete tunnel for amphibian protection. Since 2008, the Fraser Valley Conservancy has been working with local landowners in the Ryder Lake area of Chilliwack, B.C. to study migration patterns of local amphibians. There are six species in the area, including Western toads, Northern Red-legged frogs, Pacific Chorus frogs, Northwestern salamanders, long-toed salamanders, and rough-skinned newts.
