Yosemite Conservancy – Yosemite Field School: Mountain Yellow Legged Frogs and High Sierra Survivors

Living in the High Sierra requires incredible survival skills — and the region’s wildlife has some fascinating strategies!. Join us for a weekend of discovery as we explore alpine and subalpine ecosystems, learning how animals like marmots, pikas, ground squirrels, and mountain birds endure high elevation conditions.

On day one, hike around the Gaylor Lake area to observe these high elevation habitats as some species will make themselves visible, while others reveal their presence through tracks and signs. Gather that evening, with Dr. Roland Knapp, research biologist, who will share insights and stories from his work recovering the Mountain Yellow-Legged Frog. The next day, we’ll join Dr. Knapp in the field to search for frogs, toads, and tadpoles while learning about the fragile aquatic habitats they call home.

Hiking at high elevation with uphill sections and up to 8–9 miles on day two, this experience offers a rewarding physical challenge while maintaining a steady pace with plenty of opportunities to observe and learn.

This immersive program will leave you with a deeper understanding of the High Sierra’s remarkable wildlife — and a lasting appreciation for the resilience of its species.
