DescriptionFour degrees of row thinning were tested in 17-year-old loblolly pine plantations of eastern Maryland. In the following 10 years diameter and basal-area growth of tagged trees increased in relation to intensity of thinning. The heavier thinnings also had the most effect in increasing live-crown lengths and ratios and in favoring crown-class position. Volume growth was high in unthinned checks, and no thinning is recommended for pulpwood rotations. Infections by Fomes annosus were common after thinning, especially on stumps, but had no appreciable effect on growth or mortality of residual stands.
