El Uno is not only a living laboratory for scientists and researchers, but also an educational center where ranchers learn about new, sustainable grazing methods. © Dave Lauridsen
El Uno runs a “grass bank,” allowing ranchers to graze their cattle on the Conservancy’s healthy prairie lands in exchange for following sustainable practices on their own land. © Dave Lauridsen
The Janos grasslands provide critical habitat for a more than 200 migratory bird species, 30 reptiles and more than 50 mammals, including free-ranging bison. © Dave Lauridsen
