Gray wolves (Canis lupus) are the largest wild members of Canidae, or dog family, with adults ranging in weight from 18 to 80 kilograms (40 to 175 pounds), depending on sex and geographic locale. Gray wolves have a circumpolar range including North America, Europe and Asia. The wide range of habitats in which wolves can thrive reflects their adaptability as a species and includes temperate forests, mountains, tundra, taiga, grasslands and deserts.

Cooperative agriculture — partnering with farmers and ranchers to meet wildlife management objectives — is a long-standing practice on national wildlife refuges (50 CFR 29.2). Cooperative agreements between the U.S. Fish and Wildlife Service and farmers or ranchers may permit grazing by cattle or the growing of grain, hay or other crops at a refuge. The refuge benefits by producing food for wildlife or by improving natural habitat. The farmer profits by harvesting and selling some of the crop.

Why is Fish Stocking Important? The National Fish Hatchery System raises and stocks over 98 million fish and aquatic wildlife every year to support recreational fishing, tribal subsistence fisheries, and the recovery and restoration of imperiled species. National fish hatcheries across the country work with states and tribes to produce and distribute fish for recreational and conservation purposes, and provide refuge for endangered species.
