The Forest Preserves of Cook County Law Enforcement Department serves and protects people visiting the preserves and protects the Preserve’s natural lands and property by upholding and enforcing all state, county, and Forest Preserves laws and ordinances. Forest Preserves officers perform a dual role: both the conventional duties of a police officer and tasks and duties performed by conservation officers.
The Law Enforcement Department operates 24 hours a day, seven days a week. Police officers are deployed on three shifts a day to provide equitable protection for Forest Preserves properties spread widely across Cook County. In addition to traditional patrols in marked police vehicles, Forest Preserves officers conduct high-visibility patrols in the preserves, on and off the trails, on foot, bicycle, boat, ATV and through other methods.
Forest Preserves police officers are state certified and receive specialized training in conservation and ecology from the Illinois Department of Natural Resources. They are ambassadors to the public, perform conservation roles like checking for fishing licenses, and help protect the habitat and wildlife in our care, including rare and endangered species. The Law Enforcement Department also supervises the Forest Preserves Trail Watch program, which uses volunteers for additional support to the public and an official presence out in the preserves.
