Tree canopy is declining across communities in the great lakes region, contributing to increased runoff and degraded water quality

Michigan State University, in partnership with the National Park Service, received a $103,938 Cooperative Agreement award dated September 3, 2025, under the Cooperative Research and Training Programs – Resources of the National Park System (CFDA 15.945) to address declining tree canopy in the Great Lakes region. The project, which extends through March 31, 2027, will install or enhance gravel beds and plant bare-root trees in selected areas around Lake Huron and Lake Erie while engaging community volunteers in tree planting and long-term care activities. The initiative aims to improve water quality by reducing stormwater runoff through canopy restoration.

The primary deliverables include a comprehensive technical report documenting tree survival rates, establishment success, species adaptability, and landscape conditions, along with stormwater benefit assessments using analytical tools such as the Minnesota I-DRAIN Design (MIDS) Calculator and i-Tree software. Additional products consist of best management practice recommendations for federal agencies, outreach presentations targeting nurseries, builder associations, and forestry professionals, and metrics documenting volunteer participation. These outputs will inform long-term canopy restoration strategies and provide evidence-based guidance for tree planting initiatives across the Great Lakes region.

This glri-funded project, led by michigan state university in partnership with the national park service, will install or enhance gravel beds, plant bare-root trees, and engage community volunteers in tree planting and long-term care in selected areas around lake huron and lake erie. The project will document survival rates, establishment success, species adaptability, and landscape conditions, and assess stormwater benefits using tools such as the minnesota mids calculator and i-tree. Deliverables include: a technical report with an executive summary detailing survival data, cost comparisons, and projected canopy growth best management practice recommendations for federal agencies outreach presentations to nurseries, builder associations, and forestry professionals and volunteer participation metrics. The project supports long-term canopy restoration, improved water quality, and informed tree planting strategies.
