Cook County Board of Commissioners

The Forest Preserve District of Cook County is a governmental commission in Cook County, Illinois, that owns and manages land containing forest, prairie, wetland, streams, and lakes. These land holdings are primarily managed as undeveloped natural areas and for outdoor recreation. The Forest Preserve District encompasses approximately 70,000 acres (110 sq mi; 280 km2) of land or approximately 11% of the land in Cook County,[1] which contains the city of Chicago and is the most densely populated urban metropolitan area in the Midwest. The Forest Preserves also owns the lands on which the Brookfield Zoo and the Chicago Botanic Garden operate.

The Cook County Board of Commissioners also serves ex-officio as the board for the district. The Forest Preserve District headquarters is located in River Forest, Illinois.



Forest preserves serve a different purpose than urban parks and are typically maintained for the conservation and restoration of habitat. Forest preserves may contain nature centers and other facilities, picnic groves, and hiking, biking, and equestrian trails, but, apart from public golf courses, do not typically contain land set aside for other sports activities.[2]

The forest preserves are administered by the Forest Preserve District of Cook County, which operates within a special taxation district across municipal boundaries. While the Forest Preserve District as a unit of government is legally separate from Cook County, the Cook county board of commissioners, the county board president, and county clerk hold the same offices ex officio concurrently, making up the Forest Preserve District Board of Commissioners.[3]



In 1905, at the instigation of the Cook County Board of Commissioners and private nature groups (partly guided by prominent landscape architect Jens Jensen), Illinois attempted to pass a forest preserve act, but the act was not signed by the governor.[4][5] The Forest Preserve District Association was formed in 1911 after a new state law was adopted in 1909; however, the courts declared the law unconstitutional in 1911. In 1913, Illinois adopted the Cook County Forest Preserve District Act[3] that was signed by the governor and survived legal challenge. The 1913 law allowed a county board:

To acquire… and hold lands… containing one or more natural forests or lands connecting such forests or parts thereof, for the purpose of protecting and preserving the flora, fauna and scenic beauties within such district, and to restore, restock, protect, and preserve the natural forests and said lands together with their flora and fauna, as nearly as may be, in their natural state and condition, for the purpose of the education, pleasure, and recreation of the public.

A Cook County referendum required by the 1913 law was passed by voters in 1914, establishing the Forest Preserve District of Cook County,[6] and the first Board meeting was held in February 1915.[6]



The Forest Preserve District operates six nature centers used for programming and education,[7] five campgrounds,[8] and three swimming centers as of 2023.[9] The Forest Preserve District also maintains ten public golf courses. In addition to owning and managing tens of thousands of acres of forest, meadow, and wetlands,[1] both the Brookfield Zoo (managed by agreement with the Chicago Zoological Society) and the Chicago Botanic Gardens (managed by the Chicago Horticultural Society) are located on district land. In 2016, a tree-top zipline course was opened in west Cook County's Bemis Woods.[10]

Eight significant waterways flow, at least in part, through lands in the Forest Preserve District: the Chicago River, the Des Plaines River, the Little Calumet River, Salt Creek, Poplar Creek, Thorn Creek, Crooked Creek, and Tinley Creek.

National sites


The Ned Brown Forest Preserve contains Busse Woods, a National Natural Landmark. The District also administers the Chicago Portage National Historic Site. In addition, the District's Red Gate Woods was the war-time home of the Manhattan Project's first nuclear facility.



A team of district biologists and resource management professionals monitor wildlife and plants (including invasive species), water quality, and other features within the district. Monitoring may include counting population numbers and tracking the presence of animals across the district and assessing habitat needs for rare species. Through monitoring, it was discovered that river otters had returned to the district after nearly a century of absence.[11]

The Forest Preserve District owns 22 sites containing high-quality conservation resources that have been designated as Illinois Nature Preserves ensuring increased management and protection.[12] The District's oldest nature center is in a preserved rural one-room schoolhouse built in 1886 and is located in the Palos Division.[13]

The International Dark-Sky Association (IDA) conservation program designated the Forest Preserve District's Palos Preserves an Urban Night Sky Place. After review, the IDA determined that within the context of its substantial urban setting, the preserve's "planning and design actively promote an authentic nighttime experience in the midst of significant artificial light."[14]
