Herbarium specimens are dried, pressed plants that are mounted on standardized herbarium sheets. They document the occurrence of plants at a particular place at a particular time in history. The McDougall Herbarium at MNA holds over 42,000 vascular and non-vascular pressed plant specimens, mycological (fungi) specimens, 3D specimens, a small seed collection, and a bug gall collection. These specimens document the biodiversity of the Colorado Plateau, especially northern Arizona and the Grand Canyon region.

Several collections have been digitized through various efforts including: the Fort Valley Experimental Station historic collection, type specimens, a subset of rare plants, National Park Service-owned specimens, cacti, and ferns and fern allies. Only a portion of the herbarium is imaged and available to view on this Collections Portal.
