Endangered Species Conservation

PROJECTS

science to safeguard species

Science to safeguard species

UC Natural Reserve System research has laid the foundation for conserving species across the state. A prime example: UCLA professor Brad Shaffer’s work on California tiger salamanders was instrumental in protecting the upland habitats this endangered amphibian needs to survive. Watch the video >

California Tiger Salamander

Researchers at the La Kretz Center are developing a framework for protecting the genetic integrity of the endangered California tiger salamander from invasive non-natives.
