The study is part of a project for preserving the biodiversity of vascular plants in Sinite kamani Natural park and it comprises research on the possibilities for using bee colonies as pollinators. Observations have been carried out throughout the vegetation period of 2007-2009 concerning the blossoming period of nectariferous species in the park, the number and area of their populations. The blossoming of nectariferous plants in Sinite Kamani Natural Park starts in January at earliest and continues as late as November. The least number of blossoming plants has been registered at the beginning and end of vegetation and the greatest – in June. In the greater part of species extension of the blossoming period has been recorded. The main source of pollen and nectar for bees throughout the entire vegetation of woody nectariferous plants are: Cornus mas, Corylus avellana, Tilia tomentosa; Robinia pseudoacacia; Acer campestre; Acer platanoides, Crataegus monogyna. A valuable nutritional basis of herbaceous nectariferous plants are both the numerous populations of Satureja montana, Galanthus elwesii, Primula veris, Anemone ranunculoides, Viola odorata, Paeonia peregrinа, Fritillaria pontica, Pulmonaria officinalis, Geranium macrorrhizum, and those of the species of the following genera Thymus, Teucrium, Salvia, Sedum, Marrubium, Ajuga, Еchium, Echinops, Carduus, Genista, Lathyrus, Medicago, Melilotus, Potentilla, Stachys, etc. The amount of pollen and nectar throughout the entire vegetation are sufficient for providing a very good bee pasture. The data obtained give us good reason to think that on the territory of Sinite Kamani Natural Park there are very good conditions for providing continuous and lasting bee pasture throughout the entire vegetation.
