(Salem, OR) -- Officials are reminding residents that this is the time of year when snapping turtles build nests and they might be more visible. Residents who see one should call the Oregon Department of Fish & Wildlife. Snapping turtles aren't native to Oregon and can harm native turtle populations along with other mammals, birds, and fish. Snapping turtles have a long neck and a powerful bite. They can be contained with large plastic containers.
