Wolves once occupied all of North America, roaming from Canada to Mexico. However, humans have eradicated them from most of their historical range and drastically altered North American landscapes and ecosystems as a result. Defenders of Wildlife is dedicated to protecting and restoring red, gray, and Mexican gray wolves – working on the ground, in the courts, and on Capitol Hill for decades. 

“We must ensure a brighter future for wolves across the country. With the hard work of our dedicated team at Defenders and support from people like you, we can restore and protect wolves for generations to come. We will never stop fighting against anti-wolf extremists and politicians working to turn back the clock on wolf recovery. As the animals we love face some of the greatest threats we’ve ever seen, we’re grateful to have supporters like you with us.”
– Jamie Rappaport Clark, Defenders of Wildlife President and CEO.
