Abstract Depletion of natural forest due to different reasons has made the forest plantation important for extending forest area and wood production. Therefore, evaluation of forest plantation can play an important role to establish the plantation for the future. The objective of this study is to evaluate three different reforestation which was planted by Acer velutinum, Alnus subcordata and Fraxinus excelsior species. Each planted area with 49 ha was established in 1985. For data collection, 90 plots of 400 m 2 were selected randomly. Different variable such as diameter, total height, trunk length, forked tree and number of trees in different classes of diameter were assessed. The obtained results indicated that Alnus subcordata with 3.2 percent in 5 cm diameter class and 38.5 percent in 20 cm diameter class had the highest values in survival, while Fraxinus excelsior with 31.7 percent in 5 cm diameter class and 19.7 percent in 20 cm. diameter class had the lowest values in survival. Data analysis for stem quality showed that Fraxinus excelsior with 31.6 percent forked trees had the lowest value, while Alnus subcordata with 18.5 percent forked trees had the highest value in stem quality. Therefore, assuring seed quality for seedling production and protection after out planting could be resulted as a good quality of plantation.
