What Defenders Is Doing to Help Gray Wolves
For decades, Defenders has been a leader in promoting wolf recovery throughout their natusral ranges.
We were one of the driving forces behind their successful reintroduction in 1995 and 1996 into the Northern Rockies and greater Yellowstone region and led the way to reintroduce wolves to the Southwest in 1998.
Unfortunately, wolves today continue to face threats to their survival and Defenders continues to work on the ground, in the courts, and in state and federal legislatures to give America's wolves a lasting future.
