Abstract

This study aims in investigation on alteration of understory composition in Pine (Pinus eldarica Medw.) plantations with different ages. For this purpose, three Pine plantations in age of 8, 21 and 40 years were selected and sample plots were loud out in systematic-random method. Vegetation cover, density and frequency were studied for each species. Results showed that 47, 61 and 26 species were recorded for understory plants in 8, 21 and 40 years old plantations, respectively. Astragalus verus with ECOLOGICAL VALUE (EV) of 33.36 was the dominant species in the 8-year old plantation, while Aegilops umbellulata with EV of 26.31 was the dominant species in the 21-year old plantation. In the 40-year old plantation, Trifolium stellatum was the dominant species with EV of 61.87. The Similarity Index showed the highest similarity between 8-year and 21-year old plantations. The highest Shanon and Simpson Index were computed in the 21-year old Pine plantation.
