Oak Connectivity Map

Oaks are a critical part of the Chicago region's ecology. However, only 17% of the region's original oak ecosystems still 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 created hubs that buffer them and corridors to connect them.

Oaks are a critical component of the ecology in the Chicago Region. The Morton Arboretum, Chicago Region Trees Initiative, and Chicago Wilderness are working to protect and expand oak ecosystems in the region. This map shows a vision for identifying priority areas for action (cores and satellites), protecting them with buffers, and connecting them with corridors.
