75 Developing allometric functions for trees other than live trees

(1) If a project proponent chooses to account for carbon stock in project trees with the following tree status:

(a) dead standing;

(b) dead standing fire affected;

(c) live fire affected;

the project proponent must develop species‑specific allometric functions that relate to these tree status in accordance with Subdivision 12 and Subdivision 13, subject to the modifications set out in this section.

(2) In the case of dead standing trees and dead standing fire affected trees:

(a) the allometric function must relate the preferred predictor measure to stem biomass only, and not to biomass for the entire tree; and

(b) biomass contained in non‑stem components, such as branches, crown and below‑ground biomass components, must be assumed to be zero.

(3) In the case of live fire affected trees, the project proponent may:

(a) adopt the stem‑only approach specified in subsection (2); or

(b) apply the approach specified in Subdivision 13 to develop allometric functions based on sampling of entire trees, ensuring that the tree status referred to by the allometric domain is ‘live fire affected tree’.

(4) If the project proponent considers that, over time, a set of live fire affected trees has returned to a state that is equivalent to a live tree, the project proponent may revert to using an allometric function developed for live trees in accordance with Subdivision 13, subject to subsection (5).

(5) The project proponent must use the process specified in Subdivision 16 to validate the allometric function for the live fire affected trees.

(6) When the allometric function specified in subsection (5) is validated, the live fire affected trees may be reclassified as live trees.
