Evanston Trees
We're a group of neighbors who came together in August 2012 with the goal of keeping Evanston's urban forest healthy and growing. We organize work days, public programs, tree walks, and other activities to help establish young trees, raise awareness of the importance of trees, and promote best practices in tree care among residents, businesses, and other organizations. Write to us at [email protected] if you want to join in or put your name on our mailing list.

Swamp White Oak (Quercus bicolor)
Bicolor refers to the leaves being dark in color on top, and silvery light on the bottom. Native to to river flood plains in the Chicago area, this species can tolerate drought, clay soils, and flooding - a great shade tree for our region.
As keystone plants, they support over 400 species of caterpillars, which makes them a very important influence in our local, native environment. Oak trees are critical for birds when they are rearing their young in the spring. Caterpillars make up a significant percentage of of baby birds' diets, even the for ones we consider seed-eaters.
While white oaks aren't known for their fall color, they are sporting a wonderful golden mantle this Fall. The weather and moisture combinations affect the color display differently every year.
