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...
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...
Diameter increment of beech in relation to social position of trees, climate characteristics and thinning intensity
climate change dendrochronology precipitation temperature tree growth
2015/11/26
We present the results of research on diameter increment in beech stands in the area of Hostynské and Vsetínské vrchy. The data were collected on three series of permanent research plots (PRP) in midd...
Differential diameter-size effects of forest management on tree species richness and community structure: implications for conservation
Differential diameter-size effects tree species richness
2015/11/13
In this paper we tested the hypothesis that logging effects in the adult tree
community reverberate upon the regeneration contingent. We examined the differences on
the tree community between forest...
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...
Tree health influences diameter growth along site quality, crown class and age gradients in Nothofagus forests of southern Patagonia
Nothofagus pumilio annual diameter increment
2015/4/24
We examined the influence of tree health on annual diameter increment of trees along gradients in stand site quality, crown classes and tree age in Nothofagus pumilio forests of Southern Patagonia. He...
Diameter structure of the stands of poplar clones
