TREE STEM AND CANOPY BIOMASS ESTIMATES FROM TERRESTRIAL LASER SCANNING DATA [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017
In this study an automatic method for estimating both the tree stem and the tree canopy biomass is presented. The point cloud tree extraction techniques operate on TLS data and models the biomass using the estimated stem and canopy volume as independent

Exploring the Variability of Tropical Savanna Tree Structural Allometry with Terrestrial Laser Scanning [PDF]

open access: yesRemote Sensing, 2020
Individual tree carbon stock estimates typically rely on allometric scaling relationships established between field-measured stem diameter (DBH) and destructively harvested biomass. The use of DBH-based allometric equations to estimate the carbon stored over larger areas therefore, assumes that tree architecture, including branching and crown ...

Above- and below-ground competition in high and low irradiance: tree seedling responses to a competing liana Byttneria grandifolia [PDF]

open access: yes, 2008
: In tropical forests, trees compete not only with other trees, but also with lianas, which may limit tree growth and regeneration. Liana effects may depend on the availability of above- and below-ground resources and differ between tree species.

Tropical tree allometry and crown allocation, and their relationship with species traits in central Africa [PDF]

open access: yes, 2021
Common allometric patterns have been reported across the tropics and good performance on independent data was retrieved for the most recent pantropical model predicting tree aboveground biomass (AGB) from stem diameter, wood density and total height ...

Defining the allometry of stem and crown diameter of urban trees [PDF]

open access: yesUrban Forestry & Urban Greening, 2019
There is a strong allometric relationship between stem diameter at breast height (DBH) and crown diameter in healthy trees in the young to mature stages of their growth. How do geographical position, site conditions and management treatments influence this relationship?\ud \ud This study included only free-standing urban trees, thus providing data on ...

Allometry for estimating aboveground tree biomass in tropical and subtropical eucalypt woodlands: Towards general predictive equations [PDF]

open access: yes, 2005
A fundamental tool in carbon accounting is tree-based allometry, whereby easily measured variables can be used to estimate aboveground biomass (AGB).

Exploring tree growth allometry using two-date terrestrial laser scanning [PDF]

open access: yes, 2022
Tree growth is a physio-ecological phenomena of high interest among researchers across disciplines. Observing changes in tree characteristics has conventionally required either repeated measurements of the characteristics of living trees, retrospective ...
