Develop Roadway Crossings for Sensitive Amphibians

This task will develop, validate, and produce practitioner guidance for ways that sensitive amphibian taxa can use to cross roads. The taxa of interest to California Department of Transportation (Caltrans) include: Arroyo Toad, Yosemite Toad, California Red-legged Frog, Sierra Nevada Yellow-legged Frog, Mountain Yellow-legged Frogs, California Tiger Salamander, and Santa Cruz Long-toed Salamander. Areas of interest include road crossing materials, road crossing dimensions, ecological conditions within road crossings, means for preventing amphibian access to shoulders and pavement, and how to integrate amphibian road crossings with crossings for other kinds of wildlife.
