Ecological attributes and distribution of anatolian black pine [pinus nigra arnold. subsp. pallasiana lamb.holmboe] in Turkey
MetadataShow full item record
The aim of this study is to determine ecoregions and the effect of ecological properties on natural distribution of Anatolian black pine [Pinus nigraArnold. subsp. pallasiana Lamb. (Holmboe)] in Turkey. The results suggest that 6 ecoregions exist and climate, parent material, topography, anthropogenic factors, floristic composition, competition are ecological factors that determine the distribution of Black pine in Turkey. But, climatic elements such as precipitation and temperature are the dominant factors. The six ecoregions with different characteristics have been identified and distribution of Anatolian black pine revealed depending on ecological features of each region. Each region has its own characteristics that affect the growth and distribution of black pine. Productive black pine forest are found on the subhumid-semiarid areas receiving humid air mass coming from the seas either on northern or southern coastal mountains of Turkey. The poor and/or lowest productive stands occur in the semiarid parts of Inner Anatolia. Black pine can grow on all material in the semi-arid and sub-humid cold climates, but deep weatheared parent materials are the best for growing of black pine.
