[[Illinois]] has a variety of [[protected area]]s, including over 123 state-protected areas, dozens of federally protected areas, hundreds of county-level and municipal park areas, and historic sites under various governmental levels of protection. Illinois also contains sites designated as internationally important protected areas. These multiple levels of protection contribute to a statewide network of numerous recreation opportunities and conservation schemes, sometimes in a small area. For example, [[DeKalb County, Illinois|DeKalb County]] contains a {{convert|1000|acre|km2|adj=on}} [[forest preserve]] system{{Citation needed|date=July 2023}} and a {{convert|1500|acre|km2|adj=on}} state park ([[Shabbona Lake State Park]]); within DeKalb County, the DeKalb Park District in the [[Dekalb, Illinois|City of DeKalb]] has a {{convert|700|acre|km2|adj=on}} park system.<ref>{{Cite web |title=DeKalb Park District |url=https://dekalbcountycvb.com/listing/dekalb-park-district/ |access-date=July 10, 2023 |website=DeKalb County Convention and Visitors Bureau |language=en-US}}</ref>

Illinois state-owned [[protected area]]s include [[state park]]s, [[state forest]]s, state [[recreation area]]s, state fish and [[wildlife area]]s, state natural areas, and one state trail. These areas are all administered by the [[Illinois Department of Natural Resources]]. In addition, dozens of state historic sites are administered by the [[Illinois Historic Preservation Division]].<ref>{{Cite web |title=State Historic Sites |url=https://dnrhistoric.illinois.gov/experience/sites.html |access-date=July 11, 2023 |website=dnrhistoric.illinois.gov |language=en}}</ref>
