Standing Dead Trees are a Conduit for the Atmospheric Flux of CH4 and CO2 from Wetlands
Wetlands, 2018 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.

Standing-dead tree component of the boreal forest in central Saskatchewan
Forest Ecology and Management, 2000 Abstract The standing-dead tree component was assessed in part of the upland forests in the mixedwood boreal forest in central Saskatchewan. Comparisons of the average number of dead trees per hectare were made between softwood stands, softwood-dominant mixedwood stands, hardwood-dominant mixedwood stands and hardwood stands.

DETECTION OF SINGLE STANDING DEAD TREES FROM AERIAL COLOR INFRARED IMAGERY BY SEGMENTATION WITH SHAPE AND INTENSITY PRIORS [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015 Standing dead trees, known as snags, are an essential factor in maintaining biodiversity in forest ecosystems. Combined with their role as carbon sinks, this makes for a compelling reason to study their spatial distribution.

IDENTIFYING STANDING DEAD TREES IN FOREST AREAS BASED ON 3D SINGLE TREE DETECTION FROM FULL WAVEFORM LIDAR DATA [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012 In forest ecology, a snag refers to a standing, partly or completely dead tree, often missing a top or most of the smaller branches. The accurate estimation of live and dead biomass in forested ecosystems is important for studies of carbon dynamics ...

Method of Dead Standing Tree Detection Based on RetinaNet Object Detection Network
International Journal of New Developments in Engineering and Society: Aiming at the recognition of dead standing trees in UAV RGB images in forest areas, this paper proposes a dead standing tree detection method based on RetinaNet target detection network.

PLoS ONE, 2018 When standing dead trees (snags) fall, they have major impacts on forest ecosystems. Snag fall can redistribute wildlife habitat and impact public safety, while governing important carbon (C) cycle consequences of tree mortality because ground contact ...

Multispectral Blind Image Super-Resolution for Standing Dead Tree Segmentation
arXiv.orgMapping standing dead trees is crucial for acquiring information on the effects of climate change on forests and forest biodiversity. However, leveraging high-quality aerial imagery for dead tree segmentation poses challenges due to limitations in sensor

Non-negligible role of dead organic matter in a rainforest remnant in Northeast Brazil [PDF]
Rodriguésia, 2022 Dead organic matter represents an essential reservoir of carbon, especially that allocated in standing dead trees, coarse woody debris, and fine litter, playing a pivotal role in nutrient cycling and habitat provisioning. However, necromass is frequently
