Slash pine (Pinus elliottii var. elliottii Engelm.) seedlings (1-0) planted in a cutover stand dominated by 6-year-old coppiced hardwoods and woody vines benefited from reduction in root competition (by trenching) but not from increased light (by guy-wiring back overtopping trees). Over the 2-year experimental period there was no apparent effect of increasing canopy openness from 10% to 30% on pine seedling height, diameter, or aboveground biomass. In contrast, trenching resulted in increased foliar nitrogen and phosphorus concentrations, higher soil moisture contents, and a twofold increase in aboveground growth. The results support the use of site preparation and planting techniques that reduce root competition suffered by pine seedlings. South. J. Appl. For. 16(4):193-197
