Lichens are a key component of forest biodiversity. However, a comprehensive study analyzing lichen species richness in relation to several management types, extending over different regions and forest stages and including information on site conditions is missing for temperate European forests. In three German regions (Schwäbische Alb, Hainich-Dün, Schorfheide-Chorin), the so-called Biodiversi...

Northern red oak wood is valuable for a variety of applications not only in its natural distribution range North America, but also Europe. Timber quality and stem diameter largely determine timber prices respective uses. Silvicultural management key to influencing tree growth quality. In Germany, crop thinning currently the standard treatment, while Canada shelterwood system common practice. Th...

We compared indices of total hard mast production (oak and hickory combined) in 20, secondgrowth, 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 unharvested controls and stands under four reproduction cutting methods (single-tree selection, group selecti...

Stump sprouting is a widespread phenomenon in North American hardwood tree species following logging or severe crown damage from natural disturbances such as fire, wind, insect attack. However, other than the effects of and size, factors that influence probability are not well understood. Data harvested stands Pennsylvania Connecticut, USA, were used to evaluate several variables on stump frequ...

—In 2001, we initiated a study in Jackson County, AL, to examine shelterwood prescriptions in mixed mesophytic upland hardwood forests located on the escarpment of the mid-Cumberland Plateau. We were particularly interested in testing a shelterwood method that was successfully applied in other upland hardwood systems to recruit Quercus into competitive size classes. In the midstory herbicide sh...

We present 27-year results from a comparison of clear-cutting and shelterwood harvesting in the boreal forest of Alaska. Three patch clear-cut and three shelterwood units were harvested in 1972; about 100 dispersed white spruce (Picea glauca (Moench) Voss) leave trees per hectare were retained in the shelterwoods. Units were mechanically scarified and an exceptionally large seed-crop was disper...

Though longleaf pine (Pinus palustris Mill.) forests have been primarily managed with even-aged methods, interest is increasing in uneven-aged systems, as a means of achieving a wider range of stewardship goals. Selection silviculture has been practiced on a limited scale in longleaf pine, but difficulty with using traditional approaches and absence of an evaluation across a range of site types...

Silvicultural systems integrate both regeneration and intermediate operations in an orderly process for managing forest stands. The clearcutting method of regeneration favors the development of species that are moderately intolerant to intolerant of shade. In fact, clearcutting is the most proven and widely used method of successfully regenerating bottomland oak species in the South. The seed-t...
