Defenders of Wildlife is a U.S.-based organization focused on the protection and restoration of imperiled species and their habitats. Their mission emphasizes the conservation of North American biodiversity, working to prevent species from becoming endangered, protecting those already at risk, and restoring vulnerable species to healthier populations.

The organization’s efforts include advocacy, litigation, and on-the-ground conservation. This includes promoting coexistence between wildlife and humans, addressing climate change impacts on wildlife, combating invasive species, and protecting critical habitats such as wetlands, forests, and coastal areas. They also work internationally to combat wildlife trafficking and illegal trade.

Their Center for Conservation Innovation focuses on leveraging technology and science for wildlife conservation, aiming to create durable protections and push for stronger implementation of existing laws like the Endangered Species Act.
