Silviculture of Acadian Spruce-fir Forests

Robert Seymour, University of Maine Professor Emeritus of Silviculture in the School of Forest Resources (SFR), summarizes the voluminous literature and research findings on Acadian spruce-fir silviculture from the last five decades. Reviews are organized by seven major themes (plus supplementary materials) relevant to the silvicultural treatment of Acadian spruce-fir forests: The Resource, Past and Present; Soil/Site Assessment; Production Forestry; Stocking and Density Diagrams; Natural Regeneration; Multi-aged Silvicultural Systems; and Ecological Silviculture. Powerpoint lectures on the Spruce Budworm and Maine's Forest Practices Act, presented in SFR graduate classes before Seymour retired in 2017 are also available on Seymour's YouTube channel here: https://youtu.be/0Uq_ikmZNis?si=WrYStuGvaxYgeDNI
