THE STRATEGY
ill. 104 - Green density
ill. 105 - Biodiversity in Porta Romana rail yard
1.4 GREEN DENSITY According to an investigation of the biodiversity of the site made by WWF we can see which are the main species currently present on the area and how the vegetation is distributed depending on the public or private use of the space. In our proposal, we want to respect the local species and add new ones as well. The vegetation is
arranged according to green density, which consists on an orthogonal grid simplifying the plantation of the trees and their maintenance on the piazzas and a more flexible arrangement of the vegetation on the bigger open spaces. This green layer will also spread towards the surroundings of the city and boulevards.
