摘要

Young stands of loblolly and pond pine on Maryland's Eastern Shore ordinarily grow rapidly for the first 15 t0 20 years, but then slow down as competition among the dominant trees increases. Similar decreases in growth apparently occur in both plantations and well stocked natural stands. Conventional thinnings, removing scattered stems, are not very practicable in such 15 to 20 year-old stands. Cutting all the trees in selected rows in plantations, or in lanes through natural thickets, would bypass most of the difficulties.
