Buenos Aires
National Wildlife
Refuge
Watchable Wildlife List
In southeastern Arizona, the mix of deserts, mountains,
grasslands, elevation changes, and the northern limits of
many subtropical species make this geographic area one
of the most biologically rich regions of the world. Some
species are here because the core of their distribution is in
the nearby Sonoran Desert, the Sierra Madre mountain
range to the south, or the Rocky Mountains to the north.
A number of birds, mammals, reptiles, and amphibians
are here at the northern edge of their range and are found
nowhere else in the U.S. Some exist only in isolated sites
within this region.
Located in southern Arizona, Buenos Aires National
Wildlife Refuge was established 1985 for the
reintroduction of masked bobwhite quail and for
restoration of natural landscapes and their native
wildlife. The refuge features several distinct groups of
interdependent plants and animals, or biotic communities.
These are semi-desert grassland, the cottonwood/willow
riparian area, and Brown Canyon’s sycamore/walnut
community with adjacent evergreen oak woodland. This
rich combination of grassland, wetland, and sycamore/oak
canyon supports a wide array of wildlife.
Listed here are mammals, reptiles, and amphibians
recorded on the refuge and where they may be found.
Birds are on a separate checklist. The refuge has not been
thoroughly studied, and other species and locations may
be present.
