Estimating Aboveground Carbon in Live and Standing Dead Trees

2008
Carbon 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

Implications of alternative biomass and carbon estimation methods for standing dead trees in the United States

Environmental Monitoring and Assessment
New models quantifying tree volume, biomass, and carbon have recently been implemented across the USA, termed the National-Scale Volume and Biomass (NSVB) framework. Little research has been done to quantify the implications of these new models on the standing dead tree (SDT) carbon pool, which occupies a substantial portion of the nation's total ...

Deep learning and model transferability for standing dead tree mapping

Timely forest health monitoring depends on fast and accurate methods that identify tree mortality due to climate change driven phenomena such as bark beetle attacks. Aerial imagery coupled with deep learning is an efficient tool for detecting standing dead trees compared to field work but requires reliable and quickly accessible applications for forest

Distribution of early‐arriving saproxylic beetles on standing dead Scots pine trees

Agricultural and Forest Entomology, 2010
The community composition of early‐arriving saproxylic beetles on 80 standing and recently deceased Scots pine trees ( Pinus sylvestris L.) was examined.

Detecting and quantifying standing dead tree structural loss with reconstructed tree models using voxelized terrestrial lidar data

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.

Windthrows and Dead-standing Trees as Bark Beetle Breeding Material at Forest-clearcut Edge

Scandinavian Journal of Forest Research, 1999
Abstract The spatial distribution of windthrows and dead-standing trees as well as the occurrence of two bark beetle species, Ips typographus and Tomicus piniperda, were studied at forest-clearcut edges in southern Finland. More than 80% of the recorded dead trees were situated within the first 15 m from the clearcut border. The number of dead-standing
