The geographic focus of Southern Utah University's Herbarium (SUU) is the southwestern Great Basin region. As a biologically diverse area that lies at the junction of four ecosystems (Central and Mohave Basins as well as Wasatch and Colorado Plateaus), the approximately 8000 current specimens mirror an array of ecological and economical changes that have occurred in the southern Basin. In addition to historical documentation, specimens housed in the SUU Herbarium serve as a teaching tool for our students. The SUU Herbarium is also the official repository for Parashant National Monument (National Park Service).
