The Forest Preserves of Cook County has long conducted field research and has well-established partnerships with academic research institutions. The Forest Preserves are home to some of the nation’s most biologically diverse flora and fauna, inspiring a wide array of scientists and students to better understand the natural world.

Interactive Map Tells Story of Birds in Cook County & Beyond
From sparrows to sandhill cranes, Forest Preserves of Cook County biologists safely capture, handle and band an average of 400 birds per year. But what is bird banding and why do we do it?
Explore an interactive map, videos and photos that tell the story of our ongoing research to track zoonotic diseases (illnesses passed between animals and humans), uncover local environmental issues, and measure the success of our restoration efforts—all through the amazing birds that live in and migrate through Cook County.

Research Agenda
Each year The Forest Preserves’ Resource Management department issues more than 50 permits that allow researchers to conduct scientific studies on Forest Preserves land. Data from each project is shared with the Forest Preserves, allowing us to leverage resources and enrich our understanding of the natural world. Many researchers from throughout the country use Forest Preserves data to inform their work and guide land management, benefiting people, plants and animals.
The Forest Preserve engages in research to accomplish the following goals:
- Improve land management practices to maximize biodiversity.
- Understand the transmission of zoonotic diseases to protect public health, and enable additional research on the interaction between zoonotic diseases, flora and fauna.
- Expand understanding of climate change on local populations of plants and animals.
- Compile raw data to create usable and accessible databases, facilitating further analysis and study
The Forest Preserves works with a wide range of academic research partners from throughout the region and beyond, including:
- Chicago Botanic Garden
- Chicago Zoological Society/Brookfield Zoo
- Cornell University
- Field Museum
- Lincoln Park Zoo
- National Park Service
- Oregon State University
- Rutgers University
- The Ohio State University
- University of Wisconsin-Madison
- University of Illinois at Urbana-Champaign
- University of Tennessee
- University of Notre Dame
- University of Oklahoma
- University of California, Berkeley
The Forest Preserves also recruits citizen scientists who participate in long-running frog, bird, dragonfly, and plant monitor programs.
The Forest Preserves have done extensive research and data collection on zoonotic diseases, those diseases transmitted from animals to humans. The Forest Preserves’ has collected wildlife blood samples since 1988, making us one of the oldest and largest contributors to the Center for Disease Control. Our data collection was particularly useful during the first outbreaks of West Nile Virus and Lyme disease.
Urban Coyote Research Project
Urban Coyote Research Project is a partnership between the Forest Preserves, Cook County Animal & Rabies Control, Max McGraw Wildlife Foundation and The Ohio State University.
The Cook County Coyote Project is a comprehensive study of coyotes in Chicago metropolitan areas. Also known as the Urban Coyote Research Program, the study was initiated in 2000 as a non-biased attempt to address shortcomings in urban coyote ecology information and management; the Coyote Project is still underway. With the help of many key agencies, a continuous subset of coyotes is live-captured, collared, and released at their capture site. Coyotes are monitored to understand how they live in urban areas and how they interact with other wildlife, domestic animals, and humans.
Urban Coyote Research Project Website
In addition to giving researchers and the public a window into the lives of coyotes in Cook County, the project has provided training and support for multiple young researchers, including postdocs and graduate students.

Research Ideas
Looking for a research idea? Potential questions and topics:
- What are the most effective new chemical treatments of various invasive species?
- Does the full process of brush pile burning or chipping (trucks, chippers, etc.) produce more pollution?
- Is there a correlation between the incidence of prescribed burns and the occurrence of oak wilt disease?
- Is there an increase in insect diversity and plant interactions with prescribed burn practices?
- How do soil biotic elements affect ecosystem management outcomes and health?
- What are the biotic and edaphic factors that enhance a natural community’s resistance to invasive species?
- What is the impact of genetically modifying and mixing native plant communities?
Research Access Permit
Unless otherwise under contract with the Forest Preserves, all research investigations on Forest Preserve property require a Research Access Permit. Research investigations include any monitoring, collecting, testing, study, observation, investigation or other related activity, that benefit the Forest Preserves, public education or the community.
If these stipulations do not apply, or if the proposed activity includes the installation, repair or maintenance of roads, facilities, or structures, a Construction Access Permit will be required. The Research Permit has a maximum term of one year with five additional one year extensions as approved by the Forest Preserves.
