Now more than ever we need to understand urban flora-both native and invasive species. The Chicago EcoFlora project is collecting observations of plants in Cook County, Illinois to learn more about local plant life and contribute to conservation planning. With your help, we will collect data on important native species and troublesome new invaders that call our city home. This project will inform Chicago Park District, the Forest Preserves of Cook County, and other land managers about native plants that need protection and invasive species that need control.
