Height-diameter equations are important in modeling forest structure and yield. Twenty-seven height-diameter equations were evaluated for eight tree species occurring in the northern hardwood forest of New Hampshire using permanent plot data from the Bartlett Experimental
Forest. Selected models with associated coefficients are presented for American beech, eastern hemlock, paper birch, red maple, red spruce, sugar maple, white ash, yellow birch, and all 16 species combined.
Each regional journal of applied forestry focuses on research, practice, and techniques targeted to foresters and allied professionals in specific regions of the United States and Canada. The Northern Journal of Applied Forestry covers northeastern, midwestern, and boreal forests in the United States and Canada.
