30 Ex ante estimate of minimum number of TSPs or PSPs
(1) This section sets out how to make, for a stratum (the assessed stratum), an ex ante estimate of the minimum number of TSPs or PSPs needed for a full inventory or a PSP assessment.
(2) First, the project proponent must collect data from an assessment:
(a) that consists of:
(i) a full inventory or a PSP assessment that was conducted prior to working out the ex ante number in accordance with this section; or
(ii) a pilot inventory; and
(b) that was conducted in:
(i) the assessed stratum; or
(ii) another stratum that is analogous to the assessed stratum; and
(c) in which at least 5 plots were established and assessed.
Note: Section 50 limits the use of data that has been obtained when conducting a pilot inventory.
(3) Then, the project proponent must use this data and Equations 29a and 29b to make an ex ante estimate of the minimum number of plots required, using:
(a) for the minimum number of TSPs—the target probable limit of error for a full inventory; and
(b) for the minimum number of PSPs—the target probable limit of error for a PSP assessment.
(4) In this section:
pilot inventory means the collection and assessment of data in relation to project trees primarily for calculating the number of plots required to achieve a specified probable limit of error.
