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.
We take you on a visit to the west suburban forest under the watchful eye of six suspicious – and sizable – trolls.

The emerald ash borer is devastating ash trees in the area. We meet some researchers who are trying to understand the tiny green bug well enough to find an ash tree that can co-exist with this pervasive pest.
