The DSU Arboretum is an Accredited Arboretum in the Morton Register of Arboreta, the first in Delaware and at an HBCU (2013).
DSU is also a Tree Campus USA, the first in Delaware (2011).

General information:
  • The DSU Arboretum is composed of 174 different species of trees and shrubs planted on the main campus in Dover, each species labeled (115 labeled tree species, larger yellow dots on map; and 59 labeled shrub species, smaller yellow dots).
  • These include 69 native species (native to Delaware), 97 *non-native species (not native to Delaware), and 8 **adventive species (not native to Delaware, but native to N. America and now growing wild in DE).
  • All of the Arboretum trees and shrubs have educational and aesthetic value, and the native species in particular have ecological value.
  • The diversity of the campus trees and shrubs was augmented by numerous trees planted in the 1960’s-70’s (Dr. N. Dill), 57 trees and shrubs (35 new species, 2/3 native) planted in 2010-2012 by the Herbarium (Dr. S. Yost), and additional trees provided in 2012 by the Arbor Day Foundation, and DDA.
  • The DSU Arboretum developed from the Campus Tree Walk (Yost and Calabrese 2006) with the assistance of Claude E. Phillips Herbarium staff, volunteers and student workers; and was funded in part by USDA NIFA Capacity Building Program Grant #2008-38820-04790 (Yost, 2008-2012).
