| With urbanization comes transportation. For most Californian’s it is necessary to drive an automobile or take public transit. Many automobiles leave behind oily roads and such. The oil and waste from these automobiles end up in the waterways and groundwater, especially when it rains. There is no documented information on the affects of this problem on the California Red-Legged Frog. Routine road maintenance, trail development and facilities construction activities related with parks in or adjacent to California Red-Legged Frog habitat can result in increased siltation in the stream (61 Federal Register 25826). If this siltation occurs during the breeding season, asphyxiation of eggs and small California Red-Legged Frog larvae can result (61 Federal Register 25826). |
