Abstract
In the Missouri Ozarks, there is considerable concern about the effectiveness of the uneven-aged methods of single-tree selection and group selection for oak (
Quercus L.) and shortleaf pine (
Pinus echinata Mill.) regeneration. We compared the changes in reproduction density of oaks and pine following harvesting by single-tree selection, group selection, and clearcutting during a 10-year period in the Missouri Ozarks. Inventories in permanent plots were completed preharvest (1995) and post-harvest (1998, 2002, and 2006). Prior to harvesting, advance oak regeneration densities (trees < 4.5 inches diameter at breast height [d.b.h.]) ranged from 144 to 173 trees per acre. Ten years after harvesting, oak density in clearcut stands increased to 1,049 trees per acre and was about two times greater than in group openings (514 trees per acre) and more than four times greater than where single-tree selection (236 trees per acre) was used.
