Abstract

Through 11 growing seasons, growth of loblolly pine (Pinus taeda L.) increased after control of herbaceous, woody, or both herbaceous and woody vegetation (total control) for the first 3 years after planting on a bedded site in the Georgia coastal flatwoods. Gains in stand volume index from controlling either herbaceous or woody vegetation alone were approximately two-thirds that from controlling both types of vegetation. Pine response through age 11 was approximately equal for herbaceous control alone and woody control alone, whereas response through age 5 was greater with control of only herbaceous vegetation. The impact of woody vegetation should continue to have a strong effect on pine growth through midrotation because of its continued development. This is in contrast to herbaceous weeds that have greatly decreased in abundance since age 6.
