§ 1072.6. Point Count Stocking Sampling Procedure.

The silvicultural rules of each forest district and the Act contain point count stocking standards to be met following the completion of a timber operation. The following procedure shall be used to determine if these stocking standards have been met.

Since there are separate values for three different size classes, three circular concentric plots may be needed at each plot center. The following standards are for a 300 point count.

(a) For trees counted as one point each, a plot with a 6.80 foot radius is used (1/300th of an acre). If a countable tree of a value of at least one point is found in the plot, it is stocked, so recorded, and the timber owner or agent thereof moves on to the next plot center. If no countable tree is found, the next concentric plot is measured.

(b) For trees counted as three points each, a plot with a 11.78 foot radius is used (1/100th of an acre). If a countable tree of a value of at least three points is found in the plot, it is stocked, so recorded, and the timber owner or the agent thereof moves on to the next plot center. If no countable tree is found, the next larger concentric plot is measured.

(c) For trees counted as six points each, a plot with a 16.65 foot radius is used (1/50th of an acre). If a countable tree of a value of at least six points is found in the plot, it is stocked. If no countable trees of the required sizes are found in the three concentric plots, the plot center is recorded as being unstocked and the timber owner or agent thereof moves on to the next plot center. For point counts of 450 per acre, the three concentric circular plot radius sizes are: 5.55 feet (1/450th of an acre), 9.61 feet (1/150th of an acre), and 13.6 feet (1 /75th of an acre). For point counts of 150 per acre, the three concentric circular plot radius sizes are: 9.61 feet (1/150th of an acre), 16.65 feet (1/50th of an acre), 23.55 feet (1/25th of an acre).

The point count values of various size trees and for determining how sprouts will be counted is found in 14 CAC 912.7, 932.7 and 952.7.
