Résumé
This study was carried out to evaluate the success of plantations made by Artvin Environment and Forestry Directorate in order to control soil erosion along the Artvin Çoruh river basin and to determine the outplanting performance of Robinia pseudoacacia L., Cedrus libani A. Rich. and Pinus pinea L. which have been commonly planted in this region. After site preparation, 1+0 containerized P. pinea seedlings as three replicates (a total of 90 seedlings) was planted in Sumbullu plantation site, and 1+2 containerized C. libani and 1+0 bareroot R. pseudoacacia seedlings were planted as three replicates (a total of 180 seedlings) in Salkımlı plantation site. The post planting treatments were repeated twice in growing season in two sites. Root collar diameter (± 0.1 mm) and heights (± 1.0 cm) of the seedlings were measured immediately after planting, and along with survival, at the end of the first growing seasons in December 2008. All measurements were done on individual seedlings. Survival of the seedlings of the all species were high (>85%) at the end of the first year. Species significantly effected diameter and height increments and R. pseudoacacia performed more diameter and height increments in the first growing season. In Artvin Çoruh river basin R. pseudoacacia should be preferred to P. pinea and C. libani, and deciduous species (Quercus, Crataegus, Colutea, Paliurus, Cotoneaster, Cotinus etc) native to this region should be planted to prevent soil erosion.
