Ann Arbor, a city west of Detroit in Washtenaw County, has a population of nearly 121,000. The city is known for the University of Michigan and its research programs, which largely shapes Ann Arbor’s economy as the university employs 30,000 workers. Ann Arbor values its urban and community forest and residents have nicknamed the city “Tree Town.” The city-managed forest, including street trees and areas of parks, provides nearly $4.6 million in benefits annually. According to the city’s urban tree canopy assessment conducted in 2010, Ann Arbor has 33% canopy coverage. Ann Arbor has a typical Midwestern humid continental climate with four distinct seasons. The climate is influenced by the Great Lakes and the area experiences lake effect weather, primarily resulting in more cloudiness in the late fall and early winter. Understanding tree species vulnerability and key climate change impacts is critical in implementing adaptive management strategies for years to come.
