The “biosphere” is that veneer of our Earth’s crust, waters and atmosphere that supports life. It reaches from the deepest ocean floor 12 miles upward to the tops of the highest mountains and contains 193 distinct biogeographical zones or ecosystems. One of these is the vast Chihuahuan Desert of northern Mexico, southern Texas, and New Mexico. It is a biogeographical zone rich in geologic history and natural lifeforms. It is also an area exposed to a multitude of issues impacting its resources and people. Within the Chihuahuan Desert there are four “biosphere reserves,” Big Bend, Jornada, Maderas del Carmen, and Mapimi, where answers to these pressures are being sought.
We strive to collaboratively manage the region’s globally significant Chihuahuan Desert ecosystems, including their natural, cultural, aesthetic and human values, and promote opportunities for inspiration, education, research, recreation, and economically sustainable practices for this and future generations.
Where is the Big Bend Biosphere Region?
The Big Bend Biosphere Region (BBBR) was designated by UNESCO in 1976 and is special to many people in different ways. The BBBR possesses extraordinary natural and cultural resources and contains the largest intact portion of the Chihuahuan Desert ecosystems in the U.S., which is one of the most biologically rich and diverse desert ecoregions in the world. Our unique transboundary geography and collaboration with Mexican protected areas and natural monuments allows the Chihuahuan Desert ecosystems to be managed and protected as a whole – preserving its biodiversity and ecosystem services for future generations.
