Ground Vegetation Change According to the Elevation Level on Pure Fir Forests (Abies nordmanniana subsp. bornmülleriana Mattf.) in Ardiç-Bartin, Turkey

The aim of this research that is examining the changes in the flora in Uludag Fir (Abies nordmanniana subsp. bornmülleriana) stands with respect to the altitude was carried out between 2009 and 2010. The Ardıç Watershed Area, which was chosen as study area, included in Ardıç Forest Range District belongs to Ulus Forest Enterprise Directorate. 18 sample plots were established between 900 and 1,500 m altitudes in the Uludag fir stands. The average size of sample plots was chosen as 20 x 20 m. Totally 1,500 plant specimens have been collected from all sample plots. The Braun-Blanquet method was used for the determination of present plant density in this research. At the end of the identification of these specimens, 60 taxa belonging to 35 families have been determined. These taxa include 75 genera, 108 species, 13 subspecies and 3 varieties. The forest community in the study area is described as the Abies nordmanniana subsp. bornmülleriana plant association of the Euxin region
