Basal area is a measure of the cross-sectional area of trees calculated by multiplying the foresters’ constant (0.005454) by the squared diameter of each tree to determine a measure of tree area (ft2 or m2) per unit area (acre or ha). Similar to an assessment of forest canopy cover, basal area provides a measure of horizontal structure, and is closely associated with measures of vertical structure. When assessing condition of upland hardwood woodland and forest systems, the GCPO LCC Integrated Science Agenda targets a large proportion of the basal area in those systems to be composed of oak and hickory species. This endpoint targets >90% of basal area as oak and hickory for upland hardwood woodland systems and >70%...
