Urban green areas are a strategic ally in the formulation of policies aimed at managing environmental problems linked to the growth of cities. The goal of this study was to establish the importance of trees as a carbon reservoir and as a retention surface for suspended particulate matter in an urban green area such as the PUCP campus, and considering the functional characteristics of tree species, to establish species better able to provide these services. Initially, dasometric and taxonomic information was obtained for all tree individuals on the PUCP campus, and based on this information and using allometric equations, the carbon stored was quantified. For the quantification of the particulate matter retained in the leaves, the 10 most common species were chosen and using gravimetric procedures and based on established methodologies, the species that show a higher retention were determined, in parallel, functional characteristics of stems and leaves of these species were measured. The results show that 1268 arboreal individuals were recorded, arranged in 108 taxonomic species, of which 27.7% corresponds to the native flora. The calculation of the carbon stock in the trees amounts to 145,847 t, with Fabaceae, Myrtaceae and Meliaceae families storing more than 50%. Regarding the retention of particulate matter, Ficus benjamina, Brachychiton acerifolius and Tipuana tipu, are the species that accumulate the highest amount of particulate matter, exceeding 2.5 g/m2 of leaf area. The amount of carbon stored by the campus trees shows that urban green areas can be an important carbon sink, and it was also demonstrated that the leaves retain particulate matter, attenuating direct contact with people. Finally, considering the appropriate functional characteristics favors the efficient provision of these services.
