ASU earns Tree City USA honor; join us on virtual tour
Arizona State University was recently honored with a 2014 Tree Campus USA award, which Gov. Doug Ducey presented to the ASU Grounds Services/Arboretum crew at the Arizona Capitol on April 23.
The national Tree Campus USA program honors colleges and universities for promoting healthy trees and engaging students and staff in the spirit of conservation.
To mark the occasion, we present a short tour of some of the Tempe campus' 1,000 varieties of trees. Shown here is a Southern live oak (Quercus virginiana) in south Cady Mall. The tree is native to the Eastern United States. If you want to see the trees in person, use this map to know what you're looking at.
The Aleppo pine (Pinus halepensis) — this one near the Memorial Union — is native to the Mediterranean. Its sturdy wood was once used by Romans for shipbuilding.
