About Campus Trees

The University campus, located in Ann Arbor- the "city of trees"- is home to over 7,000 trees. The Central Campus area also known as the "Original Forty" Acres is the area bordered by South University, State, North University and Church Streets. The Original 40 is home to 1,022 trees. The most prevalent shade tree genus is maple (Acer) that comprises 13% of the area population. The most prevalent ornamental tree genus is crabapple (malus) that comprises 10%. There are 286 evergreen trees in the Original Forty in the five genera fir (Abies) , hemlock (Tsuga) , spruce (Picea) , pine (Pinus) and douglasfir (pseudotsuga). The most unusual genus in the Original Forty is Carolina silverbell (Halesia carolina). We have two of these on the north side of the Hatcher Graduate Library. According to Michael Dirr, this tree is native from West Virginia to Florida and eastern Oklahoma, on wooded slopes and along streambanks.

The North Campus area also known as the "Engineering Core" is the area bordered by Bonnisteel Blvd., Murfin, Hayward, and Beal Streets. It is home to 949 trees. The area has smaller, newer trees compared to the "Original Forty", a small naturalized wooded area, and a higher percentage of evergreens (35% to 28%). The most prevalent tree genus is pine (Pinus) that comprises 25% of the area's tree population and the most prevalent ornamental tree genus is crabapple (Malus) that comprises 16% of the population.

Regarding species management, the Office of Landscape Architecture and the Grounds Department have the goal of using predominantly native species in this area and having no more than 10% of any one species in the area.
