The CRSF is home to the Cooperative Forestry Research Unit (CFRU), which serves the large, commercial forest landowners of Maine and has more than 30 members representing over 8 million acres of forestland. The Northern States Research Cooperative (NSRC) is a competitive grant program funded by the USDA Forest Service to support cross-disciplinary, collaborative research in the Northern Forest; the CRSF oversees Theme 3, encompassing research that will quantify, improve, and sustain productivity of the Northern Forest as a working forest landscape. In addition to these core research programs, the CRSF engages in a wide range of outreach activities to serve our stakeholders, from the landowners to the general public. The Howland Research Forest attracts local, national, and international scientists interested in studying nutrient cycling, forest ecology, climate change, and carbon sequestration. As participants in the Center for Advanced Forestry Systems (CAFS), the CRSF helps facilitate the connections between forestry research programs and industry members to solve complex, industry-wide problems. Since 1983, UMaine researchers have conducted numerous forest management studies on the Holt Research Forest, a long-term ecosystem research area in a mid-coast Maine oak-pine forest. The Penobscot Experimental Forest, located in Bradley, is home to university and USFS researchers and nature trails open to the public.
