Performance of mixed pine-hardwood stands 16 years after fell-and-burn treatmentsThis article is part of a larger document. View the larger document here.
Four variations of the fell-and-burn technique were compared for height and volume production on dry Piedmont sites. A two-factorial randomized complete block design of winter versus spring felling, with and without a summer burn, was implemented, followed by planting of loblolly pine (Pinus taeda L.) at 15 x 15 foot spacing. After 16 growing seasons, the winter fell with summer burn treatment resulted in greater planted pine volume (1,087.1 ± 72.8 cubic feet per acre) than either unburned treatment (652.4 ± 89.2 cubic feet per acre). The winter fell with no burn treatment resulted in greater oak volume (373.5 ± 71.3 cubic feet per acre) than did either burn treatment (108.7 ± 58.3 cubic feet per acre). Modifications of the fell-and-burn treatment can be used to alter the dominance of pine or hardwood components in developing mixed pine-hardwood stands. Stands should be monitored for further effects of canopy closure, self-thinning, and growth of oaks into micro-canopy gaps.
