The U.S. Fish and Wildlife Service is proposing to expand hunting and fishing opportunities at 13 national wildlife refuges across the U.S., including two in Texas.

The proposed expansion includes migratory bird, upland game, big game hunting and sport fishing.

At the Anahuac National Wildlife Refuge, the agency proposes the expansion of migratory game bird hunting. The refuge is already open to migratory game bird hunting and sport fishing.

At the Buffalo Lake National Wildlife Refuge, the agency proposes the expansion of big game hunting. The refuge is already open to upland game hunting.

Hunting and fishing are just two of the many recreational activities available to the public across an unparalleled network of more than 560 national wildlife refuges and 38 wetland management districts. The service manages hunting and fishing programs to ensure sustainable wildlife populations, while offering traditional wildlife-dependent recreation on public lands, such as wildlife watching and photography.

Hunting, fishing and other outdoor activities contributed more than $144.7 billion in economic activity across the U.S., according to the agency’s National Survey of Fishing, Hunting and Wildlife-Associated Recreation, published every five years.

More than 90 million Americans, or 41 percent of the U.S. population age 16 and older, pursue wildlife-related recreation. The agency’s Report Banking on Nature shows that refuges pump $2.4 billion into the economy and support more than 35,000 jobs. More than 47 million visits are made to refuges every year.
