Bullfrog Eradication at a Landscape Scale in Yosemite National Park
Channel: Conservation and Adaptation Resources Toolbox
Date: 2021-02-03

Known for its dramatic landscape and towering granite walls, Yosemite National Park is also home to a unique assemblage of native reptiles, amphibians, and fishes. Non-native American bullfrogs (Lithobates catesbeianus) were introduced to Yosemite in the 1950s, with the first bullfrog documented in 1955 at the Ahwahnee Hotel’s reflection pond, and have likely contributed to the decline of many native aquatic species since. National Park Service (NPS) biologists have conducted bullfrog control since the early 2000s and have achieved eradication within 1,500 hectares of the Yosemite Valley. During this webinar, Ninette Daniele will discuss NPS bullfrog control, long-term monitoring via eDNA, and subsequent reintroduction of native species.
