In 2020, The Morton Arboretum partnered with Davey Resource Group Inc. and the Student Conservation Association to conduct its second tree census, remeasuring 1,576 plots in the city of Chicago and the seven surrounding counties of Cook, DuPage, Kane, Kendall, Lake, McHenry, and Will to gain a comparative snapshot of the regional forest and the benefits it provides.

The first census was in 2010. For the whole seven-county area, the number of trees and shrubs increased from 157,142,000 in 2010 to 172,297,000 in 2020, representing more than 194 species. In 2020, the regional forest tree and shrub canopy cover was assessed to be 23%, an increase from 21% in 2010. In DuPage County, the canopy cover increased from 26% in 2010 to 31% in 2020.

Although the number of trees and shrubs and the canopy coverage did increase, the study notes that a large percentage of the canopy is composed of species considered invasive, such as European buckthorn and tree of heaven.

In addition, based on earlier data, the Chicago Region Trees Initiative (CRTI) has developed community-specific tree canopy summaries, including Downers Grove and many other Chicago area towns.
