At the time of layout of sample plots of the species in irrigated plantations of the Punjab, data were collected from 230 trees, ranging in diameter at breast height from 2 in. (5 cm) to 14 in. (36 cm). These trees were removed in thinnings. Data from about 1070 trees were made available by Genetics branch of Pakistan Forest Institute who felled some plots of this species last year. The latter group of data consisted of small sized trees. In order to get an adequate representative sample for each diameter class, random selection of 20 to 40 trees was made from each diameter class having more than 100 trees. Finally 343 trees were used in this study.
