The urban forestation in the artisanal area of Fontanelle consists of the planting of trees and shrubs, with the aim of mitigating climate-altering emissions thanks to the storage of CO2 and the mitigation of air pollution ensured by the project plants.
The intervention area is in fact characterized by an essentially productive use, with a high traffic of heavy vehicles, and is located between the Florence-Pisa railway line and the hilly context on which the historic town of Montopoli in Val d’Arno stands.
Tree and shrub species with a good capacity to absorb climate-altering emissions were planted. In particular, the trees belong to the following species: pedunculate oak (Quercus robur), narrow-leaved ash (Fraxinus oxycarpa), field maple (Acer campestre), Judas tree (Cercis siliquastrum) and black poplar (Populus nigra).
The plants were selected in particular among those that make the greatest contributions in terms of carbon dioxide absorption and in any case capable of adapting to the stationary conditions of the planting site. Furthermore, these are species with a marked ability to tolerate excesses of edaphic humidity, since the area is characterized by the presence of numerous ditches and impluvium areas.
The planting of trees near the road has made it possible to obtain a result with a strong landscape impact, as well as being more effective in mitigating the pollutants produced by vehicular traffic. Finally, the shading of asphalt surfaces will reduce thermal extremes and improve urban comfort.
Planting holes were made of dimensions suitable for the root balls and stakes were inserted to support the plants in their first years after planting. Thanks to the installation of a temporary irrigation system, an adequate quantity of water will be ensured to guarantee the rooting of the project plants.
Finally, as part of the project, a control unit for the monitoring of pollutants present in the atmosphere was installed, provided by the CNR-IBE and called AIRQuino.
