Variations in pollen counts with respect to data for a previous sampling period were also examined. The key finding was that the spectrum contained pollen from the most characteristic local species, such as xerophytes adapted to arid conditions, ruderal and nitrophilous species, sclerophyllous Mediterranean pine and holm-oak forest and vegetation in dry watercourses. The main variations with respect to earlier data were attributable to changes in land use, with increasing production of certain crops and a growing trend towards ecological agriculture, the introduction of allochthonous species and the recovery of local flora in dry watercourses.

From 1998 to 2003 we studied ﬂoral phenology, fruit production, fruit size, airborne pollen emission and meteorology in a holm-oak natural area of South Spain. The results obtained by using a Principal Components Factorial Analysis indicated that pollen emission, up to the day where maximum pollen data are recorded, was the most important factor determining ﬁnal acorn harvest. With regard to the inﬂuence of the weather, temperature, relative humidity and rainfall of January, March and September were the most inﬂuencing variables.
