The Challenge in the Management of Historic Trees in Urban Environments during Climate Change: The Case of Corso Trieste (Rome, Italy)

This study carries out a quantitative analysis of the impact on microclimate (air temperature and thermal comfort) row 165 historical Pinus pinea L. located in central neighbourhood Rome (Italy). The starts from qualitative general stressful conditions leading to tree decline urban environment especially during extreme climate change phenomena. Subsequently, effects planting new types trees are assessed using ENVI-met, 3D prognostic non-hydrostatic model for simulation surface-plant-air interactions. Results, obtained by simulating three different scenarios which first removed then modified, show that gradual renewal existing trees, based priority criteria maturity or senescence, vegetative phytosanitary conditions, efficiency ecosystem services safety citizens, has positive comfort. By integrating current results scientific literature, final aim this work is provide stakeholders with strategic systemic planning methodology, which, innovative integrated use management modelling tools, may (i) enhance benefits greening scenario (ii) lead intervention strategies complementarity between conservation renewal.
