In 1898, American bullfrogs were imported to California for frog legs; the predators later spread across the West, eating native frogs, fish, snakes, birds and small mammals
American bullfrogs were introduced to California for food markets in the late 19th century. These frogs became invasive predators in new ecosystems lacking natural controls. Yosemite National Park conservationists worked for years to remove bullfrogs from the valley. This extensive effort finally achieved eradication from Yosemite Valley in 2019. The process highlights the challenges of invasive species management and long-term commitment.
