3.5 Stocking
Stocking describes the density of forest stands. Nonstocked (2% of Canada’s forest land) refers to forest
land known to have few trees, or where the density is below the threshold that defines stocked. The
stocking unknown class (10% of forest land) refers to areas recently subject to forest disturbances such
as fire, harvesting, windthrow, insect or disease damage, or may be abandoned farmland: the effects of
the disturbance on the area’s stocking status are yet undetermined. The remainder of forest land (88%) is
classified as stocked (Figure 20).
Stocked forest (274.9 million ha) is further defined as regenerating (1%), partially stocked (37%),
fully stocked (58%), and stocked with extent not known (4%). Seventy-nine percent of the volume, or
23 264 million m 3 , exists on 160.8 million ha of fully stocked forest (see Table 12). Figure 21 shows the
percent of forest land that is stocked, including the classes stocked, partially stocked and fully stocked;
Figure 22 shows the area of forest land where stocking is unknown, according to disturbance class.
Appendix I: Table I-9 shows the area of forest land (in thousands of hectares) by stocking class and
province and territory.
