A vast Chihuahuan Desert reserve on the Mexico, United States border, protecting one of North America's most striking river canyons.
Canyon de Santa Elena Flora and Fauna Protection Area
The Canyon de Santa Elena Flora and Fauna Protection Area is a large Mexican protected area in the northeast corner of the state of Chihuahua, straddling the border with the United States along the Rio Grande. It was established in 1994 as part of a transboundary conservation effort mirroring Big Bend National Park on the Texas side of the river.
The reserve protects a significant portion of the Chihuahuan Desert, one of the most biologically rich arid regions in North America. Its landscape combines deep river canyons, limestone and volcanic mountain ranges, broad valleys, and a wide range of vegetation types that shift with elevation. Together with adjacent protected areas on both sides of the border, it forms one of the most important contiguous desert conservation regions in the continent.
Beyond its ecological value, the area preserves a long human history, from Paleoindian hunter-gatherers through the Apache, Jumano, and Concho peoples, to Spanish colonial frontier settlements and the eventual settlement of modern ranching communities. Today it remains a working landscape of ejidos, small towns, and protected wildlands shaped by the river and the desert.
