Notes: The National Forest Carbon Monitoring, Accounting and Reporting System (NFCMARS) used by the Canadian Forest Service (CFS) to estimate greenhouse gas (GHG) sources and sinks for Canada's National Inventory Report 1990 to 2018 submission to the United Nations Framework Convention on Climate Change covers managed forest land only (excludes unmanaged forests). Data are reported by reporting zone, which are based on Canada's terrestrial ecozones with three exceptions: the Boreal Shield and the Taiga Shield ecozones are split into east and west components, the Prairie ecozone is split into sub-humid and semi-arid components and the Arctic Cordillera is excluded. For some regions, notably the Hudson Plains and Taiga Shield, only a very small proportion of forest area is considered managed. Managed boreal forest represents about half of Canada's boreal forest area. The Carbon Budget Model of the CFS (CBM-CFS3) at the core of NFCMARS is designed for use on non-frozen upland mineral soils (0 to 100 cm) and therefore excludes organic soils (peatland) and permafrost.
