Meta-Modelling to Quantify Yields of White Spruce and Hybrid Spruce Provenances in the Canadian Boreal Forest?
tree improvement growth and yield climatic transfer distances meta-model random-coefficients modelling
2024/1/23
Tree improvement programs can improve forest management by increasing timber yields in some areas, thereby facilitating conservation of other forest lands. In this study, we used a meta-analytic appro...
Soil Carbon Modelling in Salix Biomass Plantations: Variety Determines Carbon Sequestration and Climate Impacts
biomass production life cycle assessment climate impact soil organic carbon Salix willow short rotation coppice genotypic difference
2023/12/8
Short-rotation coppice (SRC) Salix plantations have the potential to provide fast-growing biomass feedstock with significant soil and climate mitigation benefits. Salix varieties exhibit significant v...
Modelling Aboveground Biomass of Miombo Woodlands in Niassa Special Reserve, Northern Mozambique
remote sensing allometric models biomass REDD+
2023/12/7
Aboveground biomass (AGB) estimation plays a crucial role in forest management and carbon emission reporting, especially for developing countries wishing to address REDD+ projects. Both passive and ac...
Modelling Soil Organic Carbon as a Function of Topography and Stand Variables
altitude slope crown cover soil organic carbon model accuracy
2023/12/1
Soil organic carbon (SOC) plays a crucial role in global carbon cycling. The amount of SOC is influenced by many factors (climate, topography, forest type, forest disturbance, etc.). To investigate th...
Modelling and mapping of soil damage caused by harvesting in Caspian forests (Iran) using CART and RF data mining techniques
forestry operations hazard zoning spatial prediction timber skidding tree ensemble techniques
2018/3/6
Controlling the soil damage caused by forest harvesting has a key role in forest management due to its effect on forest
dynamics and productivity, mainly through modifying the physical, mechanical, a...
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...
Deforestation modelling using logistic regression and GIS
manmade areas physiographic factors
2015/5/18
A methodology has been used by means of which modellers and planners can quantify the certainty in
predicting the location of deforestation. Geographic information system and logistic regression ana...
Modelling of forest road sediment in the northern forest of Iran (Lomir Watershed)
wood dams SPSS multiple regression culvert
2015/5/5
Forest roads are the most important ways of access; nevertheless, they are the main source of sediment
production. The delivered sediment by forest roads causes environmental problems and pollution ...
Modelling and analyzing the surface fire behaviour in Hyrcanian forest of Iran
burned area forest fire litter thickness
2015/5/5
The purpose of this study was to assess the forest fire behaviour and investigate the impact of different
parameters on the spread of surface fire in the Hyrcanian forest of Iran. Surface fire was s...
Modelling forest dynamics in a nature reserve: a case study from south-central Sweden
pine spruce computer simulation ecological model
2015/4/14
This paper presents a modelling study on the forest dynamics in Helgedomen Nature Reserve (HNR) in Sweden. The main components of the forest transitions that occurred between 1930 and 2010 were descri...
