46 | Council of Canadian Academies Forests | Chapter 3 Definition of NBCS Mechanism Restoration of Forest Cover Restoration of forest cover Restoration of forest cover increases the biomass includes the planting of trees where of forests through tree planting as more carbon is forests were once the dominant stored within the increased vegetation. [...] Council of Canadian Academies | 57 3.3.3 Forest NBCS Carbon Sequestration Potential in Canada The area of opportunity for forest NBCSs in Canada is limited by feasibility constraints The implementation of forest NBCSs is constrained by the size of the area over which they can feasibly be deployed. [...] 58 | Council of Canadian Academies Forests | Chapter 3 Changes in albedo offset some of the climate change mitigation benefits of expanding forest area The overall effect of the restoration of forest cover on CO2e can be significantly impacted by changes to albedo — the proportion of light reflected from Earth’s surfaces — particularly in Canada; increases in forest cover reduce surface reflectivi. [...] Council of Canadian Academies | 71 Monitoring and accounting can help establish the effectiveness of a forest NBCS Monitoring the forest sector in Canada to meet international reporting requirements relies on the Carbon Budget Model of the Canadian Forest Sector (CBM-CFS3); due to the nature of that accounting, an NBCS that focuses on avoided actions to enhance sequestration will not impact nation. [...] Uncertainties in the scope of soil carbon pools and the magnitude of forest carbon fluxes in managed and unmanaged forests, as well as forests’ responses to climate change and changes in albedo, indicate a need for additional regionally focused research to assess the feasibility of implementing NBCSs in forested areas of Canada.
