Regenerating shortleaf pine in clearcuts in the Missouri Ozark HighlandsThis article is part of a larger document. View the larger document here.
A shortleaf pine (Pinus echinata Mill.) regeneration study was established by the Missouri Department of Conservation in 1986 at the Current River Conservation Area. The objective of the study was to compare natural to artificial regeneration methods, and site preparation prescribed burning to bulldozing for shortleaf pine establishment and growth. Eighteen years after establishment, the control treatment (natural regeneration) had only 94 stems/ha, the burn treatment had 727 stems/ha, and the doze treatment had 1,680 stems/ha. Mean volume growth per tree was greatest in the doze treatment (53.7 dm³) followed by the burn treatment (34.1 dm³) with the control having the least volume growth (22.3 dm³). Hardwood competition was greatest in the control treatment (3,132 stems/ha) followed by the burn treatment (2,470 stems/ha) and least in the doze treatment (1,210 stems/ha). The results suggest that (1) survival and growth of shortleaf pine increases with increase in site preparation intensity, (2) natural regeneration may not achieve stocking goals and adequate growth, and (3) prescribed burning is a viable site preparation method.
