Current through Register 2024 Notice Reg. No. 38, September 20, 2024

(a) No more than five (5) unstocked plots shall be contiguous to each other. A contiguous unstocked plot is any plot within the rectangle constructed around the two adjacent plots on the same line and the three plots adjacent to them on the two nearest lines. See Figure 1073(a).

An unstocked plot shall not be counted as contiguous to another unstocked plot if any of the following occur:

(1) Where, in use of the point count or combination Stocking sampling procedure, an unstocked plot has a Countable Tree located in the largest circular concentric plot described in the procedure.

(2) Where the forest practice Rules allow only the basal area sampling procedure to be used, the continuity of the six contiguous plots may be considered broken if one or more of the contiguous unstocked plots meets the minimum Stocking Standards of the Act.

(b) If there are more than five (5) unstocked plots contiguous to each other, the sample shall be assumed to be understocked except where application of the following gives a number of less than six (6).

(CUP) x (SA)--(SIP) x (0.5) x (SA)is less than 6
(NPS) (NPS)

CUP--Number of contiguous unstocked plots

SA--Acres in sample area

SIP--Number of stocked intermediate plots

NPS--Number of plots in sample, excluding intermediate plots. An intermediate plot is a plot placed halfway between two unstocked plots in the sample.

(c) If less than 55% of the plots are stocked when using the basal area, point count, or combination Stocking sampling procedures, it is assumed that the area being sampled is understocked. The Timber Owner or agent thereof shall delineate the understocked areas in the report of Stocking. If the Timber Owner or the agent thereof still believes the area to be stocked, another sample may be run. The second sample shall be laid out in the same manner as the first sample, with the additional plots lying halfway between the initial plot lines. For statistical analysis, the two samples shall be combined and analyzed together.
