Note A growth disturbance is a natural disturbance that may or may not also be a significant reversal. The growth disturbance is required to be identified and delineated, but may not necessarily meet the thresholds to be considered a significant reversal under the Regulations.
When a natural disturbance that is also a significant reversal has occurred, the proponent is required to meet their obligations as outlined under section 81 of the Act, which include provisions for notifying the Regulator and re-establishing carbon stocks.

The management regime for a harvest project may be changed if the number of carbon credits issued for the project for all previous offsets reports is less than the PPACS value for the new management regime as calculated in accordance with Equation 2.10 in section 6.18.
Note Requirements for the calculation of the PPACS is detailed in section 4.9 and the calculation is provided in section 6.18. Under some circumstances, changes to the management regime can increase the value for the PPACS calculated for the project due to:

4.10 Requirements for estimating predicted project average carbon stocks
(1) If the project type is a harvest project, the project proponent must not claim crediting for carbon stocks where this would result in the total credits received exceeding the most recently reported PPACS value.
Note The PPACS sets the limit on the claimable change in carbon stocks for a project through the calculation of net abatement in Part 6.

Note For example, if above-ground biomass of a tree is predicted from measurement of stem diameter at breast height (DBH), measure DBH.

(a) be a number between 0 and 1; and
(b) not exceed the limits specified in Table 5 of Method 12.1 of the Technical Reference Guide.
Note For example FR = 0.65 indicates that the biomass is 65% of what would be there if the tree was not dead or burnt for the same given value of predictor measure.
(5) If the root:shoot ratio method in subsection 5.25 is used to estimate root biomass for the relevant allometric equation in subparagraph (3)(b), then the same ratio calculated in subsection 5.25 for a live and unburnt project tree is taken to be applicable to a dead or burnt tree for the purpose of estimating the below-ground biomass of the dead or burnt tree.
(6) The biomass of any dead or burnt trees must then be calculated using Equation 7.2 in accordance with section 6.54.

Note If the t-test demonstrates that the mean of the residuals is less than zero with statistically-significant confidence (p<0.05) then the allometric function over-predicts the value.
(3) The adjusted maximum fraction remaining values specified in subsection (2) must then be applied in all calculations of project carbon stocks for the stratum mentioned in subsection (1).
