Stand After Clearcutting

چکیده
A mixed hardulood stand composed of 33% oak (Quercus “pp.), 33% yellow-poplar (Liriodendron tulipifera L.), and 14% other spec ies, was clearcut in 1963. Twenty years lo ter a deueloping, even-aged stand of pedominantly sprout origin is domi?gated by yellow-poplar, black locust (Robinia pseudoacacia L.), red maple (Acer rubrum L.), and sweet birch (Betula lenta L.). The 0ak.s are a minor and decreasin!; compo. nent. This and other studies suggest that clearcuts on good hItes in the Southern Ap. pulachians will be dominated by aggressive intolerant speciesrnainly yello?.,-poplar. lf a larger oak component is desiled, measures to ensure Jtrong advance ~eproduction and lessen competition frou prolific .rprouters such as red maple will be neces,x1 l-y.

SPECIES COMPOSITION OF REGENERATION AFTER CLEARCUTTING SOtrrHERN APPALACHIAN HARDWOODS!.!
--Regeneration after clearcutting of Southern Appalachian hardwood stands varies substantially in species composition not only among sites of different quality and previous-stand composition, but also among sites of similar quality and similar previous-stand composition. Severe competition from less desirable species for available growing space is cOllDlon in regenerated stands. The appropriate...

Ecosystem-based forest management strives to develop silvicultural practices that best emulate natural disturbances such as wildfire to conserve biodiversity representative of natural forest ecosystems. Yet, current logging practices alter forest structure and reduce the proportion of old-growth forest and, consequently, can exert long-term effects on the dynamics of forest biota. The stand- an...
متن کاملRegeneration of Betula albosinensis in Strip Clearcut and Uncut Forests of the Qinling Mountains in China
To contribute to a better understanding of the regeneration strategy of Betula albosinensis forests and the likely reasons behind either the successful recovery or failure after strip clearcutting, we compared the population structures and spatial patterns of B. albosinensis in eight B. albosinensis stands in Qinling Mountains, China. Four cut and four uncut stands were selected, and each sampl...
متن کاملEarly Dominance of Pioneer Hardwood After Clearcutting and Removal of Advanced Regeneration
Clearcut openings were created in mixed stands of southern New England hardwoods, hemlock, and white pines to observe the development of new stands in which all species tarted simultaneously. All preexisting woody plants, except beech root-suckers and very small seedlings of red oak and hemlock, were eliminated. Natural seedfall was augmented by direct seeding of some species. The main result, ...

Within-stand variation in understory species composition and biomass was studied in 16 even-aged stands of mixed Red Alder Sitka Spruce Western Hemlock (Alnus rubra Picea sitchensis Tsuga heterophylla) forest. The sites were upland sites, and the stands were 28-39 years old. We compared understory within three categories of microsite types: Red Alder-dominated, conifer-dominated, and mixed alde...
