Roland Knapp will talk about how 90 percent of the mountain yellow-legged frogs have been disappearing, the ambitious and promising effort under way to recover these frogs, and how this approach may be applied to conserving other threatened amphibians globally. 

Knapp works for the UC Santa Barbara Marine Science Institute based in Mammoth.

The April 6 lecture starts at 6pm at Sierra Nevada College in Incline Village.

Cost is $5.
