Sequential Sampling for Assessment of Stocking Adequacy
Cutover sites can be accurately classified as adequately or inadequately stocked using the technique of sequential sampling. The manager needs to specify the levels of satisfactory and unsatisfactory stocking, and the acceptable probabilities of misclassifying a site. Previous concerns with knowing the spatial distribution of seedlings on the site seem to be of little consequence, as long as sample plots are tallied as either stocked or not stocked. Sequential sampling is most efficient when the stocking is either very high or very low. Data from cutover spruce-fir sites in northern Maine are used to illustrate the technique. Appropriate formulae are provided for the construction of sampling charts. North J. Appl. For. 2:5-8, Mar. 1985.
