Decomposition of standing dead trees in the southern Appalachian Mountains
Oecologia, 1982Decomposition of standing dead trees that were killed by fire was examined for 10 species in the Great Smoky Mountains National Park. The decrease in wood density as fire age increased was used to estimate decomposition rates. Quercus prinus had the fastest decay rate (11% yr-1) while Pinus virginiana had the slowest decay rate (3.6% yr-1) for standing

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 ...

Standing dead trees contribute significantly to carbon budgets in Australian savannas
International Journal of Wildland Fire, 2020Previous estimates of greenhouse gas emissions from Australian savanna fires have incorporated on-ground dead wood but ignored standing dead trees. However, research from eucalypt woodlands in southern Queensland has shown that the two pools of dead wood burn at similar rates.

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.

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.

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 ...

Standing Dead Trees: a Conduit for the Atmospheric Flux of Greenhouse Gases from Wetlands?
Wetlands, 2016Wetlands represent the largest natural source of methane flux to the atmosphere, which can occur across the sediment/water/plant-atmosphere interface. Of these three potential methane sources, the role of vegetation in this flux is the least well understood.
