Big Wall Ecology in Yosemite

Yosemite Valley, located in the central Sierra Nevada of California, is famous for its massive glacier-cut granite walls. When viewed from below, these one-thousand-meter-tall cliffs appear vast and lifeless. However, a rich diversity of organisms call these vertical ecosystems home. Join Yosemite Field Station Director Breezy Jackson and special guests on an exploration of an ecosystem few visit. We will zoom in on cliffs, cracks, and crevices perched high above the valley floor to encounter lichens that eat rocks, flowers with monkey faces, gravity-defying mammals and reptiles, and the fastest animals in flight.
