Northern Arizona University is home to a giant collection of dried plant specimens that scientists across the globe use as a resource center. The Deaver Herbarium is essentially a plant museum that holds more than 120 thousand samples from the Southwest, some gathered more than 100 years ago. Biologist Tina Ayers is the director and curator.
