Abstract

Intrusive competition control was used for 3 years in a nuturally regenerated, even-aged stand of loblolly and shortleaf pines (Pinus taeda L. and P. echinata Mill.) in southern Arkansas. Treatments included: no competition control, woody competition control, herbaceous competition control, and total control of nonpine vegetation. Control of gerbaceous vegetation resulted in statistically significant pine growth gains in height, groudline diameter, and volume per tree. Control of only woody competition did no improve pine growth compared to untreated checks.
