Black pine [Pinus nigra Arnold. subsp. pallasiana (Lamb.) Holmboe. var. pallasiana] and Taurus cedar (Cedrus libani A.Rich.) are commonly used species with high adaptation potential to planting sites in anthropogenic steppe and arid-semiarid regions in afforestation studies in Turkey. In this study, the effects of species and site on survival and growth of Black pine, and Taurus cedar seedlings were evaluated on three ecologically different sites (Ki-zilirmak, Ilgaz and Yaprakli) after eleven growing seasons in Turkey. One-year old tubed Black pine and two-year old tubed Taurus cedar seedlings were planted at the experimental sites in early spring. Results showed that planting site and species significantly affected seedling survival, diameter and height increment. It is thought that afforestation with Taurus cedar seedling in arid sites such as Kizilirmak and Black Pine seedlings in semiarid region such as Ilgaz at last years and semiarid regions such as Yaprakli may result better with regard to survival rates, diameter and height increase.
