Great Lakes Northern Forest Cooperative Ecosystem Studies Unit

Great Lakes Northern Forest CESU logo

The Great Lakes Northern Forest (GLNF) Cooperative Ecosystem Studies Unit (CESU) is a regional network of faculty, specialists, managers, and staff from leading academic institutions, conservation organizations, and federal agencies. All units transcend political and institutional boundaries to improve the scientific base for managing public lands. They provide resource managers with high quality scientific research, technical assistance, and education. The GLNF CESU seeks to resolve resource problems at multiple scales using interdisciplinary ecosystem studies involving the biological, physical, social, and cultural sciences. The GLNF CESU has been hosted by the University of Minnesota’s Department of Forest Resources since 2002.

Inventory of Bats at Minute Man National Historical Park to Inform Building Management, Visitor Use Planning, and Potential Consultation

Minute Man National Historical Park (MIMA) needs an inventory of bats to determine presence in areas of proposed building demolition and hazard tree management along trail corridors. An understanding of bat occupancy in these areas will allow proactive planning and appropriate timing of management actions. 

The deadline for responding to this request for LOI is January 24, 2024. 

Natural Resource Condition Assessment for Katahdin Woods and Waters National Monument: Request for LOI

Request for letters of interest
The Natural Resource Condition Assessment for Katahdin Woods and Waters National Monument will provide the National Park Service (NPS) with a Natural Resource Condition Assessment (NRCA) of Katahdin Woods and Waters National Monument (KAWW). NRCAs rely on existing data and expertise from a variety of NPS and non-NPS sources to provide a snapshot-in-time evaluation of resource conditions for a subset of important park natural resources and indicators.

Deer Population Estimation for Northeastern National Parks

Request for LOI: The northeast region of the National Park Service (NPS) has proposed an ambitious effort to improve forest resilience and prepare for the effects of climate change by addressing forest regeneration debt (Miller et al. 2023) in 17 northeastern and mid-Atlantic parks. An important component of the effort will be evaluating current park-level efforts to estimate deer population size and developing a consistent regional approach for long-term deer monitoring. Funding has not yet been announced, but the regional office has been told to expect approximately half of the funding in FY 2024, which will be sufficient to support half of the parks in the proposal as well as the work described in this request for letters of research interest.
