The Efforts to Save Guadalupe Fescue

The Guadalupe fescue is an endangered bunchgrass found in Big Bend National Park. This park hosts diverse habitats, including desert, mountains, and rivers. At the park’s center, the Chisos Mountains rise around 6,000 feet above the Chihuahuan Desert.

These mountains feature cooler forest ecosystems populated with pinyon pines, junipers, and the rare Guadalupe fescue. Referred to as ‘sky islands,’ these environments offer unique habitats distinct from their surroundings.

Located near Texas’s border with Mexico, Big Bend’s remote location has preserved the fescue’s last known patches in the U.S. However, climate change poses a threat. Species relying on these ‘sky island’ habitats face challenges as they are pushed to higher elevations.

At some point, scientists warn, they may run out of mountain.

Carolyn Whiting, a Park Botanist at Big Bend, has long monitored the Guadalupe fescue. She emphasizes the importance of preserving such species. Listed as endangered in 2017, this grass highlights the ongoing conservation efforts required in changing climates.
