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 nonscientific 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. (original abstract)
