100 Calculating mean plot carbon stock for a stratum
(1) The calculation of the mean plot carbon stock for a stratum must:
(a) be carried out in accordance with Equation 11a; and
(b) incorporate a standard error calculation in accordance with Equation 11b.
(2) The mean plot carbon stock for a stratum for the reporting period is to be calculated using the following formula:
| | Equation 11a |
| = | mean plot carbon stock for plots within the th stratum for the reporting period in tonnes per hectare of CO2‑e (t.ha‑1 CO2‑e). |
|---|---|
| = | carbon stock in carbon pools assessed within plot for reporting period in tonnes per hectare of CO2‑e (t.ha‑1 CO2‑e), calculated in accordance with Equation 12. |
| = | number of plots assessed within the th stratum during the reporting period. |
Note: For the calculations in Equation 26a substitute Image unavailable in extracted text and Image unavailable in extracted text for Image unavailable in extracted text to calculate the mean plot carbon stock for non‑fire affected and fire affected stratum respectively.
(3) When calculating the mean plot carbon stock for a stratum, the standard error is to be calculated using the following formula:
| | Equation 11b |
| = | standard error for mean plot carbon stock for plots within the th stratum for the reporting period, in tonnes per hectare of CO2‑e (t.ha‑1 CO2‑e). |
|---|---|
| = | standard deviation of plot carbon stock, for plots assessed in the th stratum for the reporting period (where is calculated in accordance with Equation 12), in tonnes per hectare of CO2‑e (t.ha‑1 CO2‑e). |
| = | number of plots assessed within the th stratum during the reporting period. |
