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. A system of component biomass equations was fitted simultaneously with a constrained seemingly unrelated Cited by: 7.

Predicted total-tree biomass of understory hardwoods. With increasing stand age, the proportion of stem biomass to total tree biomass increased from % in the year-old stand to % in the year-old stand, and the proportion of understory. The total forest biomass density estimates for determined by the application of the national biomass estimator allometric equations was Mg ha −1, which was a much lower value for the total tree biomass than the values obtained using Methods A and B (Table 2 and Table 3). The differences occurred in both the pine plantation group and Author: Doug P. Aubrey, John I. Blake, Stan J. Zarnoch.

Several factors can affect the remote sensing-based AGB estimation, such as insufficient sample data, atmospheric conditions, complex biophysical environments, scale of the study area, availability of software, spatial resolution of remotely sensed data, or mixed pixels, among others [6, 10].In order to introduce different approaches that have been developed to reduce the uncertainties Cited by: 5. The maximum understory carbon density is predicted to occur when the plot contains no trees greater than cm in diameter, and ranges from to t C ha −1, depending on forest type. The minimum understory carbon density values are predicted to be % of the tree carbon density; this minimum occurs in mature stands with high tree Cited by: predicting total tree biomass and biomass of foliage, live and dead cones, dead branches, branch bark, bole wood; based on interior Alaska data Norum [ ] provides adjustment factors for winds at midflame height ( feet ( m)) for use in Rothermel's [ ] fire behavior prediction system.

The global distribution range of D. pierrei is decreasing (Farjon and Filer, ; Norton et al., ) ().As part of our ongoing research effort, the Bawangling National Nature Reserve (°03'∼°17′E, 18°57'∼19°11′N), the Jianfengling National Forest Park (°39'∼°24′E, 18°24'∼18°58′N), the Diaoluoshan National Forest Park (°43'∼°03′E, 18°43'∼18 Cited by: 4. Title: Relationships between coastal Douglas-fir stand biomass and stand characteristics: Creator: Wong, Ann Yone: Date Issued: Description: The purpose of the study was to investigate how the above-ground tree biomass components (stem, branches, and foliage) and the ratios between these biomass components change with age, site quality, initial spacing, and total stand volume. We ran each simulation for years, averaging tree abundances over the final years to yield relativebiomass values at each of the grid points. The relative tree abundances for six tree taxa (spruce, pine, birch, oak, fir, and maple) were then mapped along with simulated total tree biomass.
