Current research was conducted in order to consider adaptibility of world industrial cunifer species in Ladjim forest zone from montainous moderate height area of Sari city from 1990 up to now based on randomized complet blok design with 14 species and provenances of cunifers in 3 replications . According to 15- years results it was indicated that Pinus nigra var calabrica and Pinus nigra var Pallasiana with 92.6 and 82.4 persent had hights viability and Doglas fir species from Washington origin with 13.9% and Doglas fir originated from Origon with 10.18% showed lowest viability performance, in Ladjim zone respectively. species originated from French with 10.6 cm diamater breast high (dbh) and Pinus sylvestris originated from Ucrine with 6.6 meter height showed the best growth quantity respectively . Beast on quality result, according to health , crown form, trunk quality , disase and figur of trees, Pinus nigra var calabrica originated from French and Pinus sylvestris with Ucrine origin had highest position among treatment wich have been tested in moderate zone of North of Iran's forests (Ladjim area) Key word : cunifers, adaptation, Iran, Forest, Ladjim
