Bullfrog Eradication at a Landscape Scale in Yosemite National Park

Learn about successful bullfrog control efforts in Yosemite National Park through this informative webinar where National Park Service biologist Ninette Daniele details the decades-long mission to protect native aquatic species. Explore how NPS biologists have worked since the early 2000s to eradicate invasive American bullfrogs (Lithobates catesbeianus) from 1,500 hectares of Yosemite Valley, after their initial introduction in the 1950s at the Ahwahnee Hotel's reflection pond. Discover the methods used for bullfrog control, implementation of long-term monitoring through eDNA techniques, and the subsequent reintroduction programs for native species in this iconic national park known for its dramatic landscapes and unique native wildlife.
