Structural Comparisons Of Four Plant Communities In The Great Dismal Swamp, Claire Virginia Dabel

Biological Sciences Theses & Dissertations

Four plant communities in the Great Dismal Swamp, located on the coastal plain in southeastern Virginia, were sampled and estimates of density, basal area and aboveground standing crop biomass were determined, Biomass was estimated as 229,800 kg/ha in the Chamaecyparis thyoides community and as 344,500 kg/ha in the Taxodium distichum community. Biomass for the two hardwood communities, the

Acer-Nyssa community and mixed hardwood (Quercus-Nyssa-Acer-Liriodendron-Liquidamber) community was estimated as 195,700 kg/ha and 194,600 kg/ha respectively and did not differ significantly (P

Dickey-Lincoln School Lakes Project

This introduction of the St. John River watershed is situated in a transitional zone between the Boreal Forest Formation and the Eastern Deciduous Forest Formation. Second-growth forests representative of these two ecosystems cover extensive areas of the project site. The boreal forest forms a broad transcontinental belt in northern North America and Eurasia, with southern montane extensions. This northern forest is characterized by evergreen, coniferous trees, predominately spruce-fir The eastern deciduous forest, composed of broad-leaved hardwoods, extends throughout the eastern United States except Florida (Dasmann, 1968; Oosting, 1956).

Dickey-Lincoln School Lakes Project

The first of four sections comprising Design Memo-randum No. 2. The other sections are: II - Dickey Dam - Spillway Design Flood, III - Lincoln School Dam - Spillway Design Flood and IV - Flood Analysis and Reservoir Regulation. la section I, hydro-logic studies will be confined generally to the drainage area of the Saint John River above the gaging station at Fort Kent, Maine. The purpose of section I is to present the climatological and streamflow data for the Saint John River above Fort Kent in order to establish hydrologic criteria for the design of the Dickey and Lincoln …
