Regression equations are used in both forestry and ecosystem studies to estimate tree biomass from field measurements of dbh (diameter at breast height) or a combination of dbh and height. Literature on biomass is reviewed, and sets of publish equation for 25 species common to the Northeastern Unites States are listed. On the basis of these equations, estimates of. biomass on forest land in the Pacific Northwest: a comparison of approaches. Res. Pap.

Live tree biomass estimates are essential for carbon accounting, bioenergy feasi Cited by:
() present two sets of equations (one for temperate deciduous and one for temperate coniferous species) giving the ratio of total biomass present in foliage, coarse roots, stem bark, and stem wood. These equations take the form: where r i is the fraction of total biomass in the i th biomass component and D is diameter at breast height. Few biomass equations were designed or parameterized with the stated purpose of being applicable to a wide geographic range, e.g., the native range of a widely- occurring species (Clark, et al. , Clark, et al. a, Clark, et al. b, Clark and Schroeder.
Ensyn owns a minority interest in the equity of the project. Côte-Nord will convert approximat dry metric tons per year of cellulosic woody biomass from local sources to biocrude. The biocrude will be sold to customers in the Northeast US and in Eastern Canada for heating purposes and as a renewable feedstock for Refinery Co-processing. BASIC CHEMICAL COMPOSITION OF THE BIOMASS COMPONENTS OF PINE, SPRUCE AND BIRCH COMPOSITION OF TREE BIOMASSES The review of the chemical composition of tree biomasses was based on the most common organic compound groups found in woody biomasses: cellulose, hemicelluloses, lignin and Size: KB.

The biomass equations have been obtained from the United States Forest Service Forest Inventory and Analysis (FIA) National Program. The equations are the same equations used to generate the Common Practice estimate for each Assessment Area (by site class where applicable).
Project Developers must use these same equations for their projects. 75 ‐ year ‐ old black spruce trees were 48 and 18% less than that of stemwood biomass (Table 2). As time series As time series of tree height were not available, stemwood biomass was inferred.
Canadian national tree aboveground biomass equations. Biomass compartments considered in Quebec: (A) Black spruce 20 20 49 48 73 20 At the stand scale, equations were developed to calculate biomass and nutrient contents (nitrogen, phosphorus, potassium, calcium, magnesium) for the different tree components (stemwood, foliage, branches and bark) of the 30 most abundant tree species using basal area.
Biomass and nutrients can be estimated for a species within a mixed stand. Introduction. Crown structure of trees controls the dynamics and growth of forest stands (Horn,Smith and Long,Han et al., ).The large differences that occur in crown shape among species often translate into substantial variation in light interception ().Crown length and foliage display differ among species, often in relation to shade tolerance and stand density, which in Cited by: 4.
The biomass of each component of a tree was estimated from dbh using Swedish equations for biomass (Marklund, ). These equations provide biomass estimates for Scots pine (Pinus sylvestris) and Norway spruce (Picea abies), for the various biomass components (stem, stem bark, living branches, dead branches, needles, stump, roots more than 5 Cited by: numerous biomass equations have been developed speciﬁcally for commercial-size loblolly pine trees grown in plantations or natural stands (e.g., Van Lear et al.

We developed four additive systems of biomass equations as follows: the first additive model system (MS-1) used the best combination of tree variables as the predictors; the second additive model system (MS-2 Cited by: 7.

However, changes in forest biomass density (Mg C ha−1) may be decoupled from changes in growth (kg C year−1) when the latter also accelerates the life cycle of trees and strains access to light, nutrients, and by: 2.

InChojnacky et al. published a revised set of biomass equations for trees of temperate US forests, expanding on an existing equation set (published in by Jenkins et al.), both of which were developed from published equations using a meta-analytical approach. Given the similarities in the approach to developing the equations, an examination of similarities or differences in carbon Cited by: 4.
Abstract: Biomass estimates are required for reporting carbon, assessing feedstock availability, and assessing forest ﬁre threat. We developed diameter- and height-based biomass equations for Western hemlock (Tsuga heterophylla (Raf.) Sarg.) and red alder (Alnus rubra Bong.) trees in Western Oregon.
In the early ’s, thousands of trees were destructively sampled across Canada by the Canadian Forest Service (CFS) as part of the ENergy from the FORest research (ENFOR) program with the objective to produce regional biomass equations for the most common tree species.
ume equations, basic density and biomass expansion factors (BEFs). Biomass expansion factors are constants that convert stem volume or mass to whole tree biomass. They may be developed into functions by including relation-ships with age or tree size (Lehtonen et al.
