Abstract
Equations for basal area growth and total cubic-foot stand volume of even-aged upland oak stands in the Boston Mountains were compared with equations published for stands in the Central States. The basal area growth and stand volume equations for the Boston Mountains were developed using data from 87 stocking plots installed between 1976 and 1981. The same merchantability limits and volume computation procedures used in the Central States were followed in compiling the basal area growth and stand volumes for the Boston Mountains data. Differences were found in the equations for both basal area growth and stand volumes. Divergences in stand volumes were more pronounced when regional taper curves were used to compute tree volumes for the Boston Mountains data. Differences in the data sets with respect to stand age, site quality, and ingrowth and mortality rates may account for the differences. Use ofthe Boston Mountains equations with stand volumes derived from regional tree-taper curves is recommended when growth and yield estimates are desired for that region.
