Mammoth Lakes 395 Wildlife Crossing project
Mule deer captured by wildlife cam after crossing Highway 395 in Mammoth Lakes. They cross the busy road to reach the ranges they’ve migrated to long before the highway existed. Images like these help monitor the wildlife activity along the highway.

What is the Mammoth Lakes 395 Wildlife Crossing Project?

Within Caltrans District 9, the highest frequency of Wildlife Vehicle Collisions (WVC) are documented on Highway 395 and Highway 203 in Mono County between the Community of Crowley Lake and the Town of Mammoth Lakes (TOML). Collisions with large mammals, mainly mule deer, come with risk of property damage or even injury to drivers. Furthermore, WVCs can negatively impact deer populations, which are important to the economy, culture, and biology of the region. This project proposes to construct a wildlife crossing corridor consisting of overcrossings, undercrossings, and an exclusion fence to reduce WVCs. There are 5 project alternatives consisting of different WVC reduction treatments along the corridor.

Next, the Eastern Sierra Wildlife Stewardship Team discuss the 395 Wildlife Crossing project and fundraising needs for this project to help wildlife safely cross the highway. The presentation is followed by a Q&A segment where audience members have the opportunity to ask questions on the project, or of Beth Pratt and her work.
