摘要

Urban trees provide vital ecosystem services such as mitigating heat island,improving air quality by removing various air pollutants,capturing rainwater,and acting as topsoil carbon storage.The aesthetic value of urban trees is also another feature that has to be considered in the context of urban greening.Classical criteria for the selection of urban trees have to respond to new challenges imposed to the cities in a near future.Global climate change factors increase the harshness of our cities,and thereby the plant resilience to abiotic stresses has also to be seriously consid-ered for planning the urban greening.Red-leafed species,characterized by the permanent presence of foliar antho-cyanins,show a greater tolerance to different environmental cues than green-leafed species commonly used in our cit-ies.In addition,red tree species own a great aesthetic value which has been underestimated in the context of urban areas,especially in the harsh Mediterranean cities.In this study,we emphasize the "privilege of being red" from different point of view,in order to drive the attention to the possibility to increase the use of red-leafed species for urban "greening".Some possible negative aspects related to their use are rebut-ted and the direction of future researches are proposed.
