Deposited airborne pollen grains in the atmosphere of Fethiye were investigated in 2003 and 2004 with using a Durham sampler. Weekly deposited pollen grains in per cm(2) were calculated. During two years, a total of 14,228 pollen grains/cm(2) were counted, which belong to 41 taxa. Of these, 22 of them belong to arboreal plants (AP), 19 to non-arboreal plants (NAP) and unidentified pollen grains were recorded. In 2003, 6,519 pollen grains and in 2004, 7,709 pollen grains were counted. Of all the pollen grains 89.62% were AP, 9.63% were NAP, and 0.75% were unidentified. According to our results, it can be reported that pollen season durations and total percentages of the most frequent pollen grains in Fethiye were; 7(th)-37(th) week for Pinus spp. (42.46) 50(th)-29(th) week for Cupressaceae/Taxaceae (25.11%) 12(th)-20(th) week for Morus spp. (9.29 %), 9(th)-44(th) week for Gramineae (4.25%), 17(th)-29(th) week for Olea spp. (3.20%), 10(th)-23(rd) week for Platanus spp. (2.93%), 12(th)-25(th) week for Quercus spp. (2.34 %), 9(th)-23(th) week for Fraxinus spp. (1.07 %). 32.58% of the pollen sum was recorded in May. The season of maximum pollen fall was from March to May, with a prevalence of arboreal pollen grains.
