Abstract

In order to determine INCREMENT for AFFORESTATION (populus deltoides) HAFTDAGHANAN in Somesara region in18-years-old (west Guilan province-Iran) (parts 5-1 & 5-2),114 trees were selected in 17 sample plot(400m2), based on their distribution in diameter classes from 15 to 55 cm (in 5 cm diameter interval). First several quantitative factors including diameter at breast height, diameter at 0.65 (m) of height, diameter at 0. 1 (m) of height and diameter at stump area were measured by using diameter tape and also tree height were measured by sounto, just the trees felled. After cutting the trees, the length and diameter from breast height up to the length where diameter is 7 (cm) was measured by using diameter tap, and also it is performed for remaining parts and branches. The results show that mean survival rate is 74.11%, mean height 33.51 (m) and mean annual of height INCREMENT is 1.86 (m), mean diameter at breast height 35.60 (cm) and mean annual of diameter INCREMENT1.97 (cm), basal area per hectare 18.45 (m2/ha), volume per hectare 535.71 (m3/ha) and mean annual of volume INCREMENT 29.76 (m3/ha).
