The NWRSAA mandates the Secretary of the Interior in administering the System to (16 U.S.C.
668dd(a)(4):
• Provide for the conservation of fish, wildlife, and plants, and their habitats within the
NWRS;
• Ensure that the biological integrity, diversity, and environmental health of the NWRS are
maintained for the benefit of present and future generations of Americans;
• Ensure that the mission of the NWRS described at 16 U.S.C. 668dd(a)(2) and the
purposes of each refuge are carried out;
• Ensure effective coordination, interaction, and cooperation with owners of land adjoining
refuges and the fish and wildlife agency of the States in which the units of the NWRS are
located;
• Assist in the maintenance of adequate water quantity and water quality to fulfill the
mission of the NWRS and the purposes of each refuge;
• Recognize compatible wildlife-dependent recreational uses as the priority general public
uses of the NWRS through which the American public can develop an appreciation for
fish and wildlife;
• Ensure that opportunities are provided within the NWRS for compatible wildlife-
dependent recreational uses; and
• Monitor the status and trends of fish, wildlife, and plants in each refuge.
Therefore, it is a priority of the Service to provide wildlife-dependent recreation opportunities,
including hunting and fishing, when those opportunities are compatible with the purposes for
which the refuge was established and the mission of the National Wildlife Refuge System.
The refuge is located in a region of high biological diversity, with influences from the
Chihuahuan, Sonoran, and Madrean geographic provinces. The refuge has documented more
than 330 species of birds and has recorded 61 species of mammals, 49 species of reptiles, and 12
species of amphibians. Buenos Aires Ranch comprised much of the present-day refuge. Hunting
was permitted by the Buenos Aires Ranch owners, and hunting activities continued uninterrupted
after 1985. An initial Hunt Plan was written in 1988, allowing the take of duck, geese, coot,
snipe, white-winged dove, mourning dove, white-tailed deer, mule deer, javelina, feral hog,
mountain lion, jackrabbit, cottontail rabbit, kit fox, gray fox, ringtail, skunk (striped, hooded,
spotted, and hog-nosed), bobcat, coyote, coati, badger, weasel, and raccoon. The refuge was
open to hunting from September 1 to March 31 with hunt seasons conforming to state regulations
within those dates. No hunting was allowed from April 1 to August 31.
Refuge hunting regulations were amended in 1994 to restrict hunted species to duck, goose, coot,
mourning and white-winged dove, cottontail rabbit, white-tailed deer, mule deer, javelina, and
feral hog. All predator (coyote and skunk) hunting was ceased except by Special Use Permit
(SUP). Feral hogs were only allowed to be taken during other permitted big game hunts and did
not have a bag limit. These changes occurred in conjunction with a new compatibility
determination (CD), environmental assessment (EA), and associated finding of no significant
impact (FONSI). Refuge regulations remained unchanged from 1995 to 2002 (no record of
regulation changes). In the refuge hunting regulations in 2003, there was no mention of feral
hogs or skunks, and coyote was by SUP only.
