Table 10. Seral stage definition for biogeoclimatic zones in NDT3

Note: The mid-seral stage, between early and mature, is not designated.

[a] Seral stages can be defined by the ages presented in this table or by stand-level attributes.

[b] This represents an average value over large geographic areas for each NDT. Consequently, forests can be found that are older than the mean event interval, as the age definition of old seral sometimes specifies.
[c] BWBS with deciduous prominent.
[d] BWBS with coniferous prominent.
[e] Those portions of CWH subject to regular extensive windthrow disturbance.
