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.
