BOONE, N.C. — In May, Appalachian State University biology students — joined by students from the University of North Carolina Asheville — traveled more than 5,000 miles across the American Southwest as part of an immersive Desert Ecology field course.
Over three weeks, students explored the Sonoran and Chihuahuan deserts, Sky Islands within the mountains, White Sands National Park, Guadalupe Mountains National Park, and Big Bend National Park while investigating how plants, animals, and entire ecosystems have adapted to some of North America’s most extreme environments. The trip was co-led by Dr. Matt Estep, professor and honors program director in App State's Department of Biology, along with Dr. Jonathan Horton and Dr. Chris Nicolay, professors in UNC Asheville's Department of Biology.

Estep shared that rather than learning ecology solely in a classroom, students experienced it firsthand through daily field observations, scientific journaling, species identification, and field presentations. From towering saguaros and resilient desert wildflowers to reptiles, mammals, and birds uniquely adapted to arid landscapes, the course emphasized learning through direct observation and inquiry. The expedition challenged students to connect geology, climate, biodiversity, and conservation while developing the field skills used by practicing ecologists.
