Oak Ecosystems Need Our Help

Oaks are a critical part of the Chicago region’s ecology. However, only 17% of the region’s original oak ecosystems remain. The remaining ecosystems are often fragmented, which makes them more likely to be invaded by exotic species and less useful to wildlife.

To help restore these remnant ecosystems, the Chicago Region Trees Initiative and Chicago Wilderness have identified the most important oak ecosystems (cores) and with the help of The Field Museum, mapped hubs that buffer them and corridors to connect them.

Is your property along a corridor or near a hub? Explore the Oak Connectivity Map below, then manage your land sustainably to help support wildlife corridors.
