Comparing the amount of biomass carbon harvested to Canada’s current fossil fuel and energy usage should allow an assessment of the extent of increase in agricultural or forest production that would be required to make a significant contribution to Canada’s energy needs; (b) Estimating the extent of waste biomass carbon streams produced by Canada’s forestry, agricultural and municipal sectors and [...] The calculation of the waste C streams was more complex and involved identifying the sources and quantities of biomass carbon that are not currently being used as a primary product, nor in the production of energy or bioproducts. [...] The proportions of inventoried and timber-productive forest lands of the total landmass of Canada are presented in Figure 2.1, and the regional distribution of forested area is provided in Table 2.1. [...] These stocks include the bole of the trees that provide the merchantable product (Section 2.3.1) and the non-stem biomass (Section 2.3.2) that includes the bark, branches and leaves of all tree species within the forest. [...] Furthermore, considerable debate amongst scientists and foresters exists in regards to the amount of biomass required for site regeneration and sustainability; the percentage of required biomass is proposed to range from 0 to 100% and it is clear that no figure will adequately account for the needs of every harvest site.
