Disking and Prescribed Burning for Loblolly Pine Regeneration
Disking and three summer prescribed burning series were compared in the Virginia coastal plain on the basis of cost and effectiveness in regenerating loblolly pine (Pinus taeda L.). Disking cost about four times more than the longest and most expensive series of summer prescribed burns. Seedling stocking was adequate for all site preparation treatments at 2 years, but significantly fewer seed were needed to produce one seedling in the three-summer-burn treatment than in any of the other treatments. The same treatment was also best in holding down crown coverage and size of the small hardwood competition. None of the treatments appeared to have a lasting effect on the shrub component of the understory vegetation.
