Aboveground Biomass Allocation of Boreal Shrubs and Short-Stature Trees in Northwestern Canada

In this follow-on study on aboveground biomass of shrubs and short-stature trees, we provide plant component (herein ‘AGB’) as well AGB allometric models for five common boreal shrub four tree genera/species. The analyzed components consist stem, branch, leaf organs. We found similar ratios to total stems, branches, leaves amongst deciduous genera/species across the southern Northwest Territories, while evergreen Picea genus differed in allocation organs compared Shrub were derived using three-dimensional variable volume predictor, determined sum line-intercept cover, upper foliage width, maximum height above ground. Tree was modeled cross-sectional area stem diameter predictor variable, measured at 0.30 m along length. For AGB, achieved better model fits (60.33 g ≤ RMSE 163.59 g; 0.651 R2 0.885) (12.62 35.04 0.380 0.735), has been reported by others. predictions resulted (18.21 70.0 0.702 0.882) branch (6.88 45.08 0.736 0.923) only slightly (30.87 11.72 0.887 0.960), which suggests that trees (<4.5 m) can be more accurately predicted opposed breast tall-stature trees. Our multi-species showed promising results predicting utilized remote sensing applications where functional types cannot always distinguished. This provides critical information modeling, required understanding carbon pools within dynamic rapidly changing Taiga Plains Shield ecozones. addition, structural equations are important integrating into accounting strategies order improve our ecosystem function.
