Study of Product of the Wood in Forests in North of Iran at Ten Years Period

Forests play a key role in stable development of a country as part of its renewable natural resources. Since utilization of forests to make wood products seems to be necessary, increase in grow-up rate of forests as well as supplying the raw materials of wood industries will have significant importance in satisfying the initial needs of a society to wood materials, industries and products. Forests of Iran used to have an area of about 18 million hectares in not so far past, though all of them did not have industrial significance. It is the northern forests of Iran which is usable in producing wood and securing industrial applications. Northern forests of Iran can be divided into four regions of Golestan, Sari, Nowshahr and Gilan with main products being used as log, timber wood, traversing, beam and tunnel woods, cattin, firewood and charcoal. There was a meaningful difference between the production volumes of different regions. Aggregation of forest roads, accessibility to mechanized exploiting equipments, type of product, conditions of tree farm, volume of signed trees, method of protection and quality of trees can all be identified as parameters which affect volume of product and supply. Generally, results from the research indicated that the product and supply volume in Sari district is more than others while Gilan, Nowshahr and Golestan are rated afterwards, respectively.
