Green spaces have seen unprecedented use during the pandemic, which has left land stewards overwhelmed by crowds, but heartened to see so many new visitors.

Oak was once the predominant tree in the Chicago area. Now most of them are gone. Ecologists have a plan to make sure they don’t disappear from the region entirely, and they need our help.

There’s still a lot that scientists don’t understand about what makes trees tick, especially when it comes to fall color. A team at the Morton Arboretum is working to unlock those secrets.

The 2020 census of the region’s trees — the largest undertaking of its kind in the country — will build on the inaugural 2010 count and help municipalities set priorities for creating healthier green infrastructure, particularly in underserved communities.

The city has given up on its ash trees, but some Chicagoans refuse to let theirs die.

The new exhibition “Nature Connects” adds colorful creatures to the arboretum’s grounds using more than half a million Lego bricks.
