Dogwood’s Mac Post Arboretum is operated under the direction of the Dogwood Elementary School, and includes input from the surrounding Lindberg Forest Neighborhood Association, and an informal coalition of partners working to enhance experiential-outdoor learning at the school. The arboretum’s mission is to promote an understanding and appreciation of trees and nature through educational activities and programs that integrate science, liberal arts, and health.  The focus is on native plant collections in an ecologically appropriate and natural setting for student and public study and quiet enjoyment. The arboretum received the Tennessee Urban Forestry Council’s 2020 Awards of Excellence “Arboretum of the Year."

Only 2 miles from the city center of Knoxville Tennessee, it is located in a natural forest with a temporary stream, a half-mile nature trail containing 51 labeled tree species, and a large number of woodland plants and wildflowers.
