Mohammadpoor PashakolaeiS. KoochY. 5200995In this study, the afforestation stands of 18.1 ha with planting interval 2x2 m of Picea abies, at the age of 44 years old was investigated to compute increment and wood production in Kelardasht plantation (North of Iran). This stand was inventoried using region map and 70x70 m inventory grid. The samples were taken by randomized-systematic method. Increment statistical factors in 32 sample plots with 500 m2 area were measured. Inside each plot, Diameter at Breast Height (DBH) of whole trees and height of four witness trees (two thickness trees inside the plot and two nearest trees to center of plot) were measured. Results of this research showed that survival percentage of Picea abies at the age of 44 years old was 39.3% in Kelardasht region. Also, the average of stand diameter, height, basal area, volume, annual volume increment and form factor were 16.86 cm, 18.20 m, 23.59 m2 ha-1, 193.73 m3 ha-1, 4.4 m3/ha/year and 0.46, respectively. Considering obtaining results and comparing them with its main habitat, the stand increment amount and statistical parameters are low.]]>Assman, E.,19611st Edn.,pp: 506-506pp: 506-506Dohrenbusch, A., S.
