Abstract

A high coefficient of variation (37. 5) was found in the estimation of mean socking (as the number of stems/ha) in a 1948 teak plantation established at Nilambur, Kerala. Theoretical sample sizes required to estimate stocking with specified levels of accuracy were determined by Rustagi's formula which indicated the need for a sampling intensity of 11. 25 percent for a 95 percent confidence level allowing a maximum of 10 percent error in the mean. This is very high and not practicable in the field, where the upper practical limit of sampling intensity is 5 percent
