Forest Stocking Determined by Sequential Stocked-Quadrat Tally
The mathematical basis for determining the limit of error of estimate in binominal populations is applied to the stocked-quadrat method of sampling the distribution of trees. A sequential examination method is suggested to make the amount of field work minimal for the precision desired in estimates of stocking. Specific recommendations are made for application of the method in the uneven-aged ponderosa pine forest. The mathematical basis is suggested as applicable to other sampling problems of forestry.
