International Journal of Applied Earth Observation and Geoinformation, 2021 Forest managers and nature conservationists rely on precise mapping of single trees from remote sensing data for efficient estimation of forest attributes. In recent years, additional quantification of dead wood in particular has garnered interest. However, tree-level approaches utilizing segmented single trees are still limited in accuracy and their ...

Wood transformation in dead-standing trees in the forest-tundra of Central Siberia
Biology Bulletin, 2009Changes in the composition of wood organic matter in dead-standing spruce and larch trees depending on the period after their death have been studied in the north of Central Siberia. The period after tree death has been estimated by means of cross-dating.

Decay patterns and carbon density of standing dead trees in California mixed conifer forests
Forest Ecology and Management, 2015Abstract Dead wood plays important structural and biogeochemical roles in forest ecosystem processes. Some aspects of woody debris dynamics have been carefully studied, but the decay patterns and carbon density of standing dead (SD) trees are only weakly characterized.

Automated Estimation of Standing Dead Tree Volume Using Voxelized Terrestrial Lidar Data
IEEE Transactions on Geoscience and Remote Sensing, 2018Standing dead trees (SDTs) are an important forest component and impact a variety of ecosystem processes, yet the carbon pool dynamics of SDTs are poorly constrained in terrestrial carbon cycling models. The ability to model wood decay and carbon cycling in relation to detectable changes in tree structure and volume over time would greatly improve such

Dead trees and protected polypores in unmanaged north-temperate forest stands of Lithuania
Forest Ecology and Management, 2004Abstract The availability of coarse woody debris (CWD) and distribution of dead trees into categories of mortality (dead standing, broken and uprooted) were investigated in north-temperate forests of central Europe (Lithuania). The studied area comprised 188.7 ha and included 18 different stands 40–130 years of age with a variety of tree species ...

Remote Sensing of Environment, 2018
Abstract The structural loss rates of standing dead trees (SDTs) affect a variety of processes of interest to ecologists and foresters, yet the decomposition of SDTs has been traditionally characterized by qualitative decay classes, reductions in wood density as decay progresses, and sampling schemes focused on estimating snag longevity.

Standing Dead Trees are a Conduit for the Atmospheric Flux of CH4 and CO2 from Wetlands
Wetlands, 2017 In vegetated wetland ecosystems, plants can be a dominant pathway in the atmospheric flux of methane, a potent greenhouse gas. Although the roles of herbaceous vegetation and live woody vegetation in this flux have been established, the role of dead woody vegetation is not yet known.

Estimating Aboveground Carbon in Live and Standing Dead Trees
2008Carbon contained in aboveground live and standing dead tree mass can represent less than 1% to over 60% of the total forest ecosystem carbon pool. Accurate assessment of this pool is important for many forest managers and ecologists. Aboveground tree mass is estimated using published allometric equations relating diameter at breast height to total tree
