An Investigation Growth Rate on Needle Leaves Species in Namin Forest (Case Study: Shoghaleh Daragh Region)

Compatibility of industrial species with low demands, especially needle leaves is essential in afforestation and reforestation development. In order to viability and growth rate study of three planted coniferous species were assessed during the year 1998 in Namin forest, Shoghaleh-Daragh region of include country name here with area 50 ha were selected. These species were Picea abies (L.) H. karst, Pinus nigra var. carmanica J.F. and Cedrus libani to achive this, a random systematic sampling network of 100x100 m dimentions including 50 sampling plots (10x10 m) with square shape were employed. In each plots, quantity of species occurrence and morphological were assessed such as height, collar diameter, crown diameter and quality characters of viability rate and crown symmetry.
