Using Tree Height, Crown Area and Stand-Level Parameters to Estimate Tree Diameter, Volume, and Biomass of Pinus radiata, Eucalyptus globulus and Eucalyptus nitens
radiata pine blue gum shinning gum diameter-height allometry crown diameter stem volume above-ground biomass growth and yield modeling remote sensing
2023/11/22
Accurate estimates of tree diameter, height, volume, and biomass are important for numerous economic and ecological applications. In this study, we report exponential equations to predict tree DBH (cm...
Estimation of diameter at breast height from mobile laser scanning data collected under a heavy forest canopy
mobile mapping system clustering point cloud circle fit
2018/3/6
Mobile laser scanning (MLS) is time-efficient technology of geospatial data collection that proved its ability to provide
accurate measurements in many fields. Mobile innovation of the terrestrial la...
Investigating the variation of diameter and height of Populus sp. clone I-214 under various fertilization treatments in northern Greece – a case study
biomass production Entisols fertilizers general linear model multivariate procedure young poplar trees
2017/4/6
The study of young poplar tree characteristics like initial diameter and height as well as mineral fertilization that promotes the rapid growth of trees for biomass production was the aim of this rese...
Nonlinear mixed effect height-diameter model for mixed species forests in the central part of the Czech Republic
height-diameter relationship multi-layered forest stand model localization Naslund’s model prediction error
2016/11/11
Various forest models that estimate volume, site index, growth and yield, biomass, and sequestrated carbon amounts are based on the information of the tree heights. The tree heights are obtained eithe...
Accuracy of Structure from Motion models in comparison with terrestrial laser scanner for the analysis of DBH and height influence on error behaviour
hand-held digital camera point cloud stem optimization image segmentation photogrammetry
2016/9/2
With the advantage of Structure from Motion technique, we reconstructed three-dimensional structures from two-dimensional image sequences in a circular plot with a radius of 6 m. The main objective of...
Response of diameter and height increment to thinning in oak-hornbeam coppice in the southeastern part of the Czech Republic
drought European hornbeam growth of sprouts sessile oak soil moisture stump basal area
2016/6/3
The objective of this paper was to test the hypothesis that growth and soil moisture would increase after heavy thinning in seven years old oak-hornbeam coppice stand. Effects of thinning on (i) diame...
A COMPARISON OF OBJECT-BASED AND PIXEL-BASED APPROACHES TO ESTIMATE LIDAR-MEASURED FOREST CANOPY HEIGHT USING QUICKBIRD IMAGERY
Canopy height Geographic object-based image analysis
2015/11/16
Canopy surface height (CSH) is a significant forest biophysical parameter to estimate above-ground biomass and carbon content.
High- spatial resolution optical remotely sensed data have shown promis...
Generalized additive models as an alternative approach to the modelling of the tree height-diameter relationship
nonparametric method Norway spruce Petterson function
2015/7/2
Generalized additive models were tested using three types of smoothing functions as an alternative for
modelling the height curve. The models were produced for 23 forest stands of Norway spruce (Pic...
The Effects of Tree Height and Growth on the Density of Feeding Sites of the Cypress Bark Moth Epinotia granitalis (Lepidoptera: Tortricidae) in a Young Japanese Red Cedar Plantation
annual growth Cryptomeria japonica Epinotia granitalis larval feeding site tree size
2009/8/27
The author examined the effects of tree height and growth on the density of larval feeding sites of the cypress bark moth Epinotia granitalis, which causes wood discoloration in conifer plantations in...
Limitations and Mechanisms of Height Growth in Trees
allocation allometry aging hydraulic limitation hydrostatic limitation
2009/8/24
Height growth and maximum tree height vary among species as well as with site conditions. Maximum tree height is an important factor determining the outcome of competition for light, vertical stratifi...
Diameter at breast height-crown diameter prediction models for Picea orientalis
Crown diameter diameter-crown diameter model oriental spruce regression analysis
2010/9/10
Seven models for predicting crown diameter using diameter at breast height were tested for Picea orientalis L. (Link.) in Artvin. Data were obtained from 4208 trees measured on 117 temporary sample pl...
