General Information About Wolves

Historically, wolves roamed throughout the lower 48 states, but centuries of misconceptions and hostility toward the species led to intense human persecution. These factors coupled with habitat loss effectively wiped out the species throughout most of the country during the twentieth century.

Defenders of Wildlife has been a leader in wolf conservation since wolves first appeared on the federal endangered species list. Defenders helped restore wolves to the Northern Rockies and played key roles in the reintroduction of Mexican gray wolves to the Southwest and red wolves to the Southeast.

Wolves and the Endangered Species Act

In 1973, gray and red wolves were two of the first species placed under federal protections by the Endangered Species Act . Under these protections, wolf populations have reestablished in portions of the lower 48 states, but many challenges remain.
