Crown Encroachment into Openings Cut in Appalachian Hardwood Stands
A study was made to determine the rate and extent of border-tree crown expansion into openings cut to obtain reproduction in sawtimber stands of Appalachian hardwoods. Measurements were made on poletimber- and sawtimber-sized trees of red oak and yellow-poplar. A regression was developed for each species, based on the independent variables of tree d.b.h. and the number of years since cutting. Red oak crowns extended farther and grew faster laterally than yellow-poplar crowns. However, the rate of crown encroachment into openings was surprisingly slow for both species.
