The final decision on Greenspace returns policy makers’. Neither the Habitat fragmentation nor the multifunctional green frame are yet taken into consideration. The policy adopted by the public authorities is to maintain existing green spaces and increase their rate in the city, but unfortunately their efforts and resources are insufficient.
