33  Estimating stocking density
          (1) Stocking density for a CEA may be estimated by:
           1.     counting every tree and shrub, and dividing the total number by the area of the CEA; or
           2.     systematic random sampling in accordance with subsection (2).
          (2) If systematic random sampling is used to estimate stocking density, intended plot locations must be selected in accordance with section 36.
          (3) The methods specified in subsection (1) may be undertaken by:
           1.     on-ground measurement; or
           2.     using date-stamped, geo-referenced, remotely-sensed imagery.
          (4) To estimate stocking density by on-ground measurement:
           1.     plots must be established within the CEA at intended plot locations;
           2.     each living tree and shrub in the plot must be counted; and
           3.     the stocking density for the CEA must be calculated using the calculations specified in Division 8.
          (5) To estimate stocking density using date-stamped, geo-referenced, remotely-sensed imagery:
           1.     the imagery must have:
               1.             a horizontal accuracy that meets the CFI Mapping Guidelines; and
               2.             a pixel resolution of 2.5 metres or better so that individual trees can be differentiated; and
               3.             plots established at each intended plot location selected as specified in subsection (2); and
           2.     each living tree and shrub in the plot must be counted; and
           3.     the stocking density for the CEA must be calculated using the calculations specified in Division 8.
