; ;
A two year old study was remeasured to examine the longer-term effects of herbaceous competition control measures on the survival and height growth of Virginia pine. In the original study, eight herbicide treatments and mechanical scalping were used to control established herbaceous vegetation in the immediate vicinity of the newly planted tree seedlings. In the first growing season, the competition control measures significantly improved tree survival, but had no effect on height growth. After two years, no significant effect was observed on survival, but height growth was improved by the treatments. In both the 1982 and 1984 measurements, mechanical scalping appeared to be more detrimental to the seedlings than applying no competition control measures.
