Source: Canada's National Forest Inventory, combined remeasured (2007-2017) and projected (2006-2017 with NFI projection system) data, where plots with strong indicators of artificial change are removed. Artificial change between successive plot measurements can be caused by using different image sources, incorporating vintage baseline inventories, and updating photo-interpretation techniques (Version 3.1, November 2025) (http://nfi.nfis.org)
Note: The Arctic ecozones (Arctic Cordillera, Northern Arctic, Southern Arctic), and the Taiga Plains and Hudson Plains ecozones located in Nunavut, are not inventoried. These non-inventoried areas total 262,189.89 thousand ha.

* When the calculated RSE value is inflated, usually due to the associated change estimate being small (near 0), a cap of 200% is substituted for presentation purposes.
