Abstract
Poplars, a fast-growing species, enjoy a high significance in Iran’s industry. So far, information on poplar plantation, such as area, volume, and harvest, has been obtained by non-scientific and poor methods. A few studies have been conducted to recognize capability of poplar plantation about area, volume, harvest, distribution, and species in three high efficient provinces, i.e., Eastern/ Azerbaijan, Zanjan, Kermanshah, and Ardabil. A Cluster sampling a standard sampling method for conducting similar researches was selected, consisting of two phases. In the first phase we collected library information and half-open interview from villagers. In the second phase field measurement in the villages of these four provinces was considered. Obtained information from field measurement was erected poplar volume, cultivated poplar area, prevalent species and estimating volume via volume and weight tables. Results obtained from the present study indicate that average annual utilization volume of four provinces was 172628.84 m3, with an average error of 14.19 percent.
Highlights
Considering wood product needs of the country and disability in producing sufficient wood from northern forests, developing the poplar plantation area is inevitable in Iran
A number of factors have halted the development of poplar plantation in different regions and severely caused poplar cutting and changed these lands into agriculture land
Changes of area, standing volume and annual harvest can partly determine the development of wood products in the future
Summary
Considering wood product needs of the country and disability in producing sufficient wood from northern forests, developing the poplar plantation area is inevitable in Iran. A number of factors have halted the development of poplar plantation in different regions and severely caused poplar cutting and changed these lands into agriculture land. After 11 years in 2003 statistics for planting forests to produce wood shows a small increase/ (i.e., from 2000000 m3 to 2500000 m3 per year). Changes of area, standing volume and annual harvest can partly determine the development of wood products in the future. With identifying different species of poplar in different regions, the possibility of optimal use of this wood material for various industrial applications will be provided
