ReU represents one of the continent's most important sites for migratory birds and iconic species, such as the American bison, black-tailed prairie dog and golden eagle.
ReU has a plan for prescribed burning to reduce flammable material and renew rusty grass. In addition to reducing fire risk, this activity helps increase the area of prairie dog colonies and maintain habitat for migratory grassland birds.
In the second half of 2023, CLO successfully carried out low-stress management of 367 bison using a new marking system that can be considered satisfactory two years after its implementation. Likewise, ReU maintained its commitment to being a center for projects related to grassland conservation and its ecosystem's characteristic fauna. The CLO team continues to work on developing a monitoring plan. It continues to be a central training point for students of various levels, offering the opportunity for educational visits and professional internships for students, particularly from the University of the State of Sonora and the Autonomous University of Chihuahua.
