Permits to conduct research in each park must be obtained from individual park resource managers. Links to permit application procedures and requirements can be found on the National Park Service web site:
The Sabbatical in the Parks Program was created to assist in arranging faculty sabbaticals for researchers to conduct scholarly activity in parks in order to advance and disseminate understanding of park resources. Many units of the national park system have field laboratory facilities and housing to accommodate tenured university faculty in research endeavors. A link to sabbatical descriptions and applications can be found on the National Park Service website:
Each park associated with the Great Lakes Research and Education Center may have facilities including field laboratories, office space, lodging, and conference rooms for faculty and student researchers' use while conducting in-park research.
The GLREC Field Research Station is located at Indiana Dunes National Lakeshore.
The primary function of the research station is to provide housing, laboratory, and equipment support to enable researchers in the biological, physical, cultural, and social sciences to investigate the natural and cultural resources of the Great Lakes National Parks. The center has developed a research station that has four offices with DSL, wet chemistry area, and laboratory equipment. Equipment includes a laminar flow hood, water purifier, drying oven, incubator, balances, dissecting and compound microscopes, and some field supplies. The lab has coded access for researchers. Storage space for researchers’ field supplies is located in a detached garage.
Two dormitories, which are former private residences, are available for researchers at Indiana Dunes NL to use during prolonged stays in the park. These provide three dorm rooms in each building, and are equipped with washers and dryers, furniture, and kitchen utensils. Linens are NOT provided. Reservations for dorm use must be made in advance of fieldwork after a research permit is issued. The daily lodging fee ranges from $9.31 to $11.42.
Other Network Parks also offer limited facilities to conduct research.
Since 2004 the GLREC has offered research internships for undergraduate and graduate students during summer months to conduct studies in national parks of the Great Lakes region. The goals of the program are to: 1) support the education and career development of students and recent graduates via research opportunities, and 2) provide needed data and information pertaining to important issues and problems associated with resource management in parks. The program meets the NPS Call to Action, which provides scholarly opportunities to students. Funding for research internships is up to $2,500 per season.
