Extension: Urban Forestry

Urban foresters attend to trees within the City of Knoxville.

The importance of trees, vegetation, and landscaping in urban areas cannot be understated. They help to cool cities, improve air quality and water quality, and help create desirable, pedestrian-friendly spaces. Our Urban Forestry Extension provides valuable, expert information on tree and urban landscape care and maintenance for private citizens, municipalities, and industry.
