This study was carried out on 2 permanent plots of Quercus cerris L. var. cerris woodland in the Kurupelit region of Samsun, northern Turkey. Grime’s CSR strategies were determined for 85 plant species from the 2 study plots (61 and 50 species from plot 1 and plot 2, respectively) according to the method that was applied. | Research Article Turk J Bot 34 (2010) 521-529 © TÜBİTAK doi: Classification of some plant species according to Grime’s strategies in a Quercus cerris L. var. cerris woodland in Samsun, northern Turkey Mahmut KILINÇ, Neslihan KARAVİN , Hamdi Güray KUTBAY Ondokuz Mayıs University, Faculty of Arts and Science, Department of Biology, Kurupelit, Samsun - TURKEY Received: Accepted: Abstract: This study was carried out on 2 permanent plots of Quercus cerris L. var. cerris woodland in the Kurupelit region of Samsun, northern Turkey. Grime’s CSR strategies were determined for 85 plant species from the 2 study plots (61 and 50 species from plot 1 and plot 2, respectively) according to the method that was applied. Most of the plant species in both plots had secondary and tertiary strategies, and this suggests that plants were exposed to more than one pressure factor. In both plots, CR (competitor-ruderal) was the most common strategy.

Örnek parsellerden toplanan bitkilerin Grime’in CSR stratejileri belirlenmiştir. Araştırma kapsamında 1. örnek parselden 61, 2. örnek parselden 50, toplamda 85 türün CSR stratejisi belirlenmiştir. Araştıma sonuçlarına göre, her iki alanda da bitkilerin büyük bir kısmı ikincil ve üçüncül strateji göstermektedir. Bu da bitkilerin birden fazla baskıya maruz kaldığını ifade etmektedir. Her iki örnek parselde de en çok bulunan bitki stratejisi CR’dir (competitor-ruderal).
