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...
Allometric Equations for Estimating Biomass and Carbon Stocks in Afforested Open Woodlands with Black Spruce and Jack Pine, in the Eastern Canadian Boreal Forest
allometric equations black spruce jack pine boreal forest open woodland afforestation carbon sequestration
2024/1/12
Allometric equations use easily measurable biometric variables to determine the aboveground and belowground biomasses of trees. Equations produced for estimating the biomass within Canadian forests at...
Long-Term Soil Fertility and Site Productivity in Stem-Only and Whole-Tree Harvested Stands in Boreal Forest of Quebec (Canada)
forest biomass whole-tree harvesting soil productivity site quality index soil provinces
2023/12/19
Using residual biomass from forest harvesting to produce energy is viewed increasingly as a means to reduce fossil fuel consumption. However, the impact such practices on soil and future site producti...

The improved spatial resolution of SPOT-5 data opens for improved forestry applications, such as improved cutting delineation, identification of soil scarification activities and for monitoring of the...
ESTIMATING INDIVIDUAL TREE HEIGHTS OF THE BOREAL FOREST USING AIRBORNE LASER ALTIMETRY AND DIGITAL VIDEOGRAPHY
Laser altimetry Tree Height Boreal Forest Videography
2014/12/22
Estimation of tree heights for large territories is either expensive if done in the field or imprecise when accomplished through automated stereophotogrammetry. While scanning laser altimetry provides...
BIOMASS ESTIMATION USING VERTICAL FOREST STRUCTURE FROM SAR TOMOGRAGHY: A CASE STUDY IN CANADIAN BOREAL FOREST.
