    Pollen spectrum collected by honeybee foragers (Apis mellifera anatoliaca) was recorded during the main pollen flow in Bursa (N-W Anatolia) lowland region in order to prepare a calendar of honeybee used pollen loads, which will be useful for regional and itinerant beekeepers. Fifty one plant taxa were identified and eighteen of them had percentages higher than 1%. Dominant taxa were; Brassicaceae (13.00%), Papaver spp. (11.99%), Paliurus spina-christi (10.23%), Cistaceae (8.03%), Ranunculus spp. (7.29%) and Rosaceae (6.32%), while Echium spp. (4.34%), Trifolium repens (4.33%), Quercus spp. (4.33%), Salix spp. (4.29%), Plantago spp. (3.87%), Vicia spp. (3.48%), Trifolium pratense (3.15%), Asteraceae (2.35%), Helianthus annuus (2.15%) and Fabaceae (2.11%) were appeared with medium percentages. There is a strong reliance on some indigenous plant species for pollen foraging activity but a number of cultivars are also seen within the samples. The most diverse period for collecting various pollen types was June.
