Chicago is set to invest $46 million in tree planting over the next five years. Trees can help improve air quality, reduce flooding, and offer several other health and social benefits. But the distribution of trees throughout Chicago is far from equal.

The city has been testing alternatives to open-trench digging and tree removal during pipe replacement and repair projects. Failure of one new technique spelled the end of the line for a slew of trees in Chicago’s Andersonville neighborhood.

Currently, the city’s tree canopy cover is at 16%, a 3 percentage point decrease since 2010, according to a 2020 census of Chicago’s trees led by the Morton Arboretum. (WTTW News)

The City Council has unanimously approved an ordinance to create an Urban Forestry Advisory Board — charged with strategically caring for Chicago's urban tree canopy.

“Trees need care like streets need repairing,” said Malcolm Whiteside, deputy commissioner for Chicago’s Department of Forestry, who threw his support behind the creation of an Urban Forestry Advisory Board.

The unusually high volume of seeds falling from trees this spring, especially from the city’s elms, is indicative of drought, said Jeff Brink, senior forester with the Chicago Department of Transportation.

Between 2010 and 2020, Chicago’s canopy cover decreased from 19% to 16%, largely due to the loss of mature ash trees, according to the 2020 tree census spearheaded by the Morton Arboretum.
