Community Trees Program

The Morton Arboretum’s Community Trees Program helps communities, public and private landowners, land managers, tree professionals, and groups interested in trees to effectively manage and care for our urban and community forest. Our urban and community forest is not just the trees found in our nature preserves and parks, but also the trees along streets, outside office buildings, within homeowners associations, and even in private yards.

This urban forestry outreach program offers a wide range of information and assistance:

Purpose and history

The philosophy of the program is that all trees, on both public and private land, together form an urban and community forest that is as important a part of a community’s infrastructure as its streets and water mains.

Collectively, the green infrastructure of trees and their ecosystems provide important services and benefits: Their beauty and shade make neighborhoods more livable and improve property values. Their roots hold topsoil. Their shade saves energy in homes and buildings. Their leafy canopies and spreading roots absorb rainwater, which help to reduce flooding and replenish groundwater. They shelter wildlife, including birds that control insect populations. Their foliage absorbs air pollution. They store carbon and release oxygen. They help form the character of a community and inform seasonal changes.

But trees in urban areas need people to protect and maintain them. The goal of the Community Trees Program is to provide people with the knowledge and tools to help trees live long, productive lives. 

The Community Trees Program was established in 2002 with support from the Grace Bersted Foundation.  It is an integral part of the Chicago Region Trees Initative and builds on findings of the Regional Tree Census that was produced in cooperation with the US Forest Service.
