abstract = {Urban trees provide many benefits to citizens but also have associated disservices such as pollen allergenicity.
Pollen allergies affect 40% of the European population, a problem that will be exacerbated with climate change
by lengthening the pollen season. The allergenic characteristics of the urban trees and urban parks of the city of
Valencia (Spain) have been studied. The Value of Potential Allergenicity (VPA) was calculated for all species. The
most abundant allergenic trees with a very high VPA were the cypresses, followed by Platanus x hispanica and
species of genera Morus, Acer and Fraxinus, with a high VPA. On the contrary, Citrus x aurantium, Melia azedarach,
Washingtonia spp., Brachychiton spp. and Jacaranda mimosifolia were among the most abundant low allergenic
trees. VPA was mapped for the city and a hot spot analysis was applied to identify areas of clustering of high and
low VPA values. This geostatistical analysis provides a comprehensive representation of the VPA patterns which
is very useful for urban green infrastructure planning. The Index of Urban Green Zone Allergenicity (IUGZA) was
calculated for the main parks of the city. The subtropical and tropical flora component included many entomophilous
species and the lowest share of high and very high allergenic trees in comparison with the Mediterranean
and Temperate components. Overall, a diversification of tree species avoiding clusters of high VPA
trees, and the prioritization of species with low VPA are good strategies to minimize allergy-related impacts of
urban trees on human health.},
