Defenders of Wildlife is an American non-profit conservation organization founded in 1947. Based in Washington, D.C., the organization focuses on protecting native animals and plants in their natural habitats throughout North America. The organization works through legal action, scientific research, public education, and advocacy to protect endangered species and promote wildlife conservation. The organization played a significant role in shaping and defending major environmental legislation in the United States, including the Endangered Species Act of 1973. Defenders of Wildlife maintains various programs focused on specific conservation issues, including wolf recovery, polar bear protection, and renewable energy development that minimizes impacts on wildlife. The organization operates through multiple approaches, including litigation, policy advocacy, and on-the-ground conservation projects. They work closely with federal and state agencies, Native American tribes, and other conservation groups to achieve their objectives. Defenders of Wildlife also manages a wildlife compensation trust to reimburse ranchers for livestock losses caused by wolves, promoting coexistence between wildlife and human activities. The organization publishes a quarterly magazine called “Defenders” and maintains an active presence in policy discussions at both federal and state levels. They are supported by more than two million members and supporters nationwide.
