Research and Field Observations

The Forest Preserve District of Cook County has long conducted field research and has well established partnerships with  academic research institutions.  The more than 68,000 acres of natural lands are home to some of the region’s most biologically diverse flora and fauna and inspire scientists and a wide array of students to better understand the natural world.  Many researchers from throughout the country depend on District data to add to our knowledge base and improve natural systems that benefit not only people, but also plants and animals.
