About Campus Trees

Campus Forestry Management Plan

The University campus, located in Ann Arbor- the "city of trees"- is home to over 16,000 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 nearly 1200 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%.

A portion of the North Campus area is known as the "Engineering Core" area is bordered by Bonnisteel Blvd., Murfin, Hayward, and Beal Streets. It is home to 795 trees. The area has smaller, newer trees compared to the "Original Forty." The North Campus has a unique landscape feature compared to the Central Campus due to the 325 acres of woodlands and meadows

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 throughout the Ann Arbor campus.
