| الوصف: | The present study is a first attempt at applying the pollentrap method in the Central Stara Planina Mts by investigating the relationship between pollen assemblages and source vegetation. Five pollen traps were placed in Mt Shipchenska for four consecutive years (2002–2005). Moss samples were also collected from the immediate vicinity of the traps. The values obtained for the pollen traps are presented in percent and compared for each of the four years and with the values obtained for the moss samples. The results of the pollen traps are presented also as Pollen Accumulation Rate (grains cm-2 yr-1). They indicate that the Pinus pollen is overrepresented in the pollen traps and in the moss samples, but the moss samples show higher Pinus and Picea percentage than the pollen traps, probably due to the different type of collection and preservation of pollen grains. The cyclicity of the Fagus pollen productivity explains the variation in Fagus values in the pollen spectra. The higher pollen accumulation in the 2002/2003 pollen traps for Quercus, Corylus, and Betula indicates more favourable climatic conditions and more intensive flowering in 2003. |
