  Overview
Buenos Aires National Wildlife Refuge
Buenos Aires National Wildlife Refuge is a place where you can enjoy a landscape like few others - where sparrows flock in winter, antelope play, and the valley bottom is once again the sea of grass that greeted early settlers. Additions to the refuge since 1985 protect valuable wetland and riparian habitats at Arivaca Creek, Arivaca Cienega, and Brown Canyon. This combination of grasslands, wetlands, cottonwood-lined streambeds, and sycamore and live oak mountain canyons preserve some of the southwest's rarest habitats used by seven endangered species, ten species of concern, and many other native pants and wildlife.

Wildlife and Habitat

Over 320 species of birds have been recorded at Buenos Aires NWR. Pronghorn, mule deer, coyote, and javelina are some of the mammals frequently seen along refuge roads. Mountain lion, coatimundi, ring-tailed cats, and badger are present, but more secretive. Desert tortoise and gila monsters thrive a short distance from water-dependant amphibians and a myriad of cactus grow within a stone's throw of watercress. In addition to the masked bobwhite quail, Buenos Aires NWR protects habitat for seven other endangered species - Pima pineapple cactus, Kearney bluestar, Peregrine Falcon, Southwest Willow Flycatcher, Gila topminnow, Chiricahua leopard frog, and jaguar.

Management Activities
Re-establishing a U.S. breeding population of masked bobwhite quail is a priority at Buenos Aires NWR. Service employees work with ranchers in Mexico to restore the grasslands where the last wild birds are found.

One tool used to restore the native grassland is controlled burning. This helps slow the invasion of mesquite and revitalizes the soil. As the system recovers, the grasses, shrubs, flowers, insects, and animals of the Sonoran grassland will benefit.
