Unmanned?aerial?vehicles (UAV)-based canopy height modeling under leaf-on and leaf-off conditions for determining tree height and crown diameter (case study: Hyrcanian mixed?forest)
canopy height model digital elevation model forest inventory unmanned aerial vehicles (UAVs) tree crown architecture
2023/12/1
Tree height and crown diameter are two common individual tree attributes that can be estimated from unmanned aerial vehicle (UAV) images thanks to photogrammetry and structure from motion. This resear...
Age-independent diameter increment models for mixed mountain forests
Age-independent growth equations Algebraic difference approach Mixed effects models Uneven-aged forest Mixed species forests Growth index
2023/11/20
Mixed mountain forests with an uneven-aged structure are characterized by a high tree-growth?variability making traditional age-dependent?growth?models inapplicable. Estimating site productivity is ye...
Modelling of tree diameter growth using growth functions parameterised by least squares and Bayesian methods
growth function nonlinear least squares Bayes diameter estimation
2015/4/14
The purpose of this paper is to present a new growth and yield function (denoted as KM-function), which was empirically derived from the cumulative density function of the Kumaraswamy probability dist...
The effect of different stand density on diameter growth response in Scots pine stands in relation to climate situations
diameter growth Pinus sylvestris precipitation temperature thinning
2015/3/19
The effect of stand density on the resistance of Scots pine (Pinus sylvestris L.) to climatic stress and subsequent response of diameter increment were investigated using data gathered from six long-t...
A linkage among whole-stand model, individual-tree model and diameter-distribution model
forecast combination linkage parameter recovery stand growth and yield model
2015/3/19
Stand growth and yield models include whole-stand models, individual-tree models and diameter-distribution models. In this study, the three models were linked by forecast combination and parameter rec...
