Age Class: One of the intervals, commonly 10-20 years, into which the age range of trees are divided for classification. The growing tip of a tree stem or root. Apical meristem: Aspect: The direction towards which a slope faces. Basal Area: The cross sectional area of the stem of a tree at 4.5 feet above the ground (dbh). The basal area of a stand is the summation of all the trees or classes of trees per unit area of land. Basal area is expressed in square feet per acre. Basal area is directly related to stand volume and density. Biomass: The total weight of all harvestable vegetation from a stand. This term can also be used to describe a harvest that results in all material being processed into chips.
