Primeros registros aerobiológicos en la reserva de la biosfera «Sierras de Francia y Béjar» (centro-oeste de la Península Ibérica)

Abstract

Atmospheric pollen and pteridophyte spores content was analysed during 325 days of year 2011 in the Biosphere Reserve «Sierras de Francia y Béjar» (MW Spain; Villanueva del Conde Municipal District) by means of Hirst Volumetric Spore Trap. Moreover, a portable Spore Trap was used due to an electric failure of fixed one mainly in May. During the studied dyas, 57 types of pollen and 1 type of pteridophyte spore, Pteridium, in the atmosphere of the analyzed area were identified. Airborne pollen levels of Quercus, Castanea, Olea and Ericaceae, together with low concentrations of pollen grains from ornamental species widely used in urban areas such as Platanus, reveal the environmental importance of this world-renowned wildlife Reserve.
