Assessment of the plantation is fundamental for managers to improve plantation quality and successful plantation in the future. This study aimed to assess and compares Makhmalkooh forest park plantation data due to 18 years old period. Sampling was performed in a randomized systematic design using 60 circular plots in a 50*150 m rectangular grid. Diameter at breast height, basal area, tree height and crown canopy were measured for each species in all plots, and then total volume and mean of growth increment based on age were computed. Results showed that Cupressus arizonica and Amygdalus scoparia had the highest value in density, heterogeneity in species composition, and crown canopy and Capressus sempervirens and Olea europea had the least one. The survival rate for all species were 78.5 percent and different plantation types showed significant difference in diameter, basal area, crown canopy and total volume. The most value in mean of diameter and height increment was assigned to Pinus brutia and Cupressus sempervirens and the least value were assigned to Olea europea and Amygdalus scoparia. The results showed that Cupressus arizonica and Pinus brutia are the best species for afforestation in this region.
