We used a spatially explicit landscape model, LANDIS, to simulate the effects of five management alternatives on a 3216 ha forest landscape in southeast Missouri, USA. We compared management alternatives among two intensities of even-aged management with clearcutting, uneven-aged management with…

Interest in appropriate management approaches for sustaining longleaf pine (Pinus palustris Mill.) forests has increased substantially during the recent decade. Although long-leaf pine can be managed using even-aged techniques, interest in uneven-aged methods has grown significantly as a result of…

Clearcutting creates habitat for many species of early successional songbirds; however, little information is available on bird use of small forest openings created by group selection harvests. Group selection harvests are increasing on the White Mountain National Forest due to negative public…

Developing uneven-aged structure in mature stands of longleaf pine requires scientifically based silvicultural systems that are reliable, productive and sustainable. Understanding seedling responses to varying levels of site resource availability within forest gaps is essential for effectively…

Light, soil moisture, and tree reproduction were measured at five positions in six openings on each of three aspects in southern Illinois. Amount of light received was clearly related to position in the light openings, opening size, and aspect. More moisture was available in the centers of the…

During the 1996, 1997, and 199X breeding seasons, WC located and monitored Hooded Warbler (Wilsonia citrina) nests in a bottomland forest and examined the effects of edge proximity, edge type, and nest-site vegetation on nesting success. SW- cessful Hooded Warbler nests were more concealed from…

We compared indices of total hard mast production (oak and hickory combined) in 20, second-growth, pine-hardwood stands under five treatments to determine the effects of different reproduction treatments on mast production in the Ouachita Mountains. We evaluated mast production in mature…

Thirty openings, 9, 18, and 27 meters in diameter, were created by group-selection harvest on a high quality site in northern California in 1963. In 1991, or 28 years after site preparation, the plant community in the openings had stabilized at 55 species. A major shift was from annuals to…

The results of a half-century of experience and research with uneven-aged silviculture within the loblolly-shortleaf pine type of the Southern United States are summarized, and silvicultural guidelines for developing and managing uneven-aged stands are provided in this publication.
