The University of Nevada, Reno was designated a state arboretum by the 1985 Nevada Legislature. The campus is a living collection of plants, trees, shrubs, flowers, ornamentals and native flora-with many designated areas on campus open to the public for enjoyment and educational pursuits. The wide variety of trees on campus represents over 60 genera and about 200 species, many with several cultivars present. Thirty-six stately elms line the Main Quad, located just north of Morrill Hall, the oldest building on campus.
