Francisco José González Minero, Pilar Candau Fernández-Mensaque

• A research has been carried out about the pollen types of arboreal and shrubby origin identified in the airborne of Huelva (SW Spain) and its connection with the vegetation of the area, The aeropalynological sampling of the air was carried out in a four years term with the help of a our trap. A total amount of 35 different types have been identified representing a 65,21% of all the pollen caught. In the pollen spectrum, we can find mainly pollen of Querrus, Pinaceae. Eucalyptus, Olea and Cupressatieae that shows the huge unities of vegetation (Eucalypils forest. holm and cork oaks, pines, olive trees and conifers). In a smaller degree we have captured as well the pollen of the bush areas (Eriraceae, Cistaceae, Labiatae. Papilionaceae, Pistacia, Rhamnus...), the river communities (Alnus, Fr ins, Neriwn and Tamarix), the urban vegetation (Casuarina, Patinae, Platanus, Acacia, Litmus, Salicaceae...) and the regional vegetation (Las/anew), and interregional (Benda).
