A Bayesian Approach to Estimating Seemingly Unrelated Regression for Tree Biomass Model Systems
Bayesian approaches seemingly unrelated regression Korean larch Markov chain Monte Carlo Gibbs sampler
2024/1/19
Accurate estimation of tree biomass is required for accounting for and monitoring forest carbon stocking. Allometric biomass equations constructed by classical statistical methods are widely used to p...
A STELLA-Based Model to Simultaneously Predict Hydrological Processes, N Uptake and Biomass Production in a Eucalyptus Plantation
biomass eucalyptus N uptake STELLA model water use
2023/12/21
Eucalyptus is one of the fastest growing hardwoods for bioenergy production. Currently, few modeling tools exist to simultaneously estimate soil hydrological processes, nitrogen (N) uptake, and biomas...
Application of a model for the evaluation of the “Visitor Satisfaction” in a nature reserve of South Italy
protected areas recreational services local development assessment preferences Sicily

Impact of plot size and model selection on forest biomass estimation using airborne LiDAR: A case study of pine plantations in southern Spain
airborne laser scanning forest inventory regression survey design genetic selection methods
2017/4/6
We explored the usefulness of LiDAR for modelling and mapping the stand biomass of two conifer species in southern Spain. We used three different plot sizes and two statistical approaches (i.e. stepwi...
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...
A two-layer canopy model with thermal inertia for an improved snowpack energy balance below needleleaf forest (model SNOWPACK, version 3.2.1, revision 741)
improved snowpack energy balance canopy model
2015/8/11
A new, two-layer canopy module with thermal
inertia as part of the detailed snow model SNOWPACK
(version 3.2.1) is presented and evaluated. As a by-product
of these new developments, an exhaustive ...
Using linear mixed model and dummy variable model approaches to construct compatible single-tree biomass equations at different scales – A case study for Masson pine in Southern China
aboveground biomass dummy variable model linear mixed model Pinus massoniana
2015/4/14
The estimation of forest biomass is important for practical issues and scientific purposes in forestry. The estimation of forest biomass on a large-scale level would be merely possible with the applic...
