Growth and yield of thinned upland oak stands in the Boston Mountains of Arkansas

Abstract

Eighty-seven permanent plots were installed in natural even-aged upland oak (Quercus sp.) stands in the Boston Mountains of Arkansas on an array of sites and representing a range of ages. These plots were subsequently thinned to stocking levels of 40, 60, 80, and 100%. Measurements were taken at plot establishment and 5 and 10 yr after thinning. We developed a system of equations from these data to predict projected total basal area per ac and current and projected values for the following stand variables: quadratic mean dbh, total ft³ volume per ac, merchantable ft³ volume per ac, sawtimber ft³ volume per ac, and bd-ft volumes per ac for the three principal log rules--Doyle, Scribner, and International 1/4 in. Forest managers can use these equations to predict the growth and yield potential of upland oaks stands in the Boston Mountains.
