In the past, the areas for extractive activities were situated for the 80% in the province of Perugia and 20% in the province of Terni.

Today, we can see that the 32% of these quarries have been re-landscaped for the sake of the natural environment and the surroundings; 35% has been partly restructured while 33% will need the support for re-landscaping work.

Thus, we can classify the quarries in this following way:

First class:   32%   They don’t need any works for recovery
Second class: 35% They need a little supporting works
Third class: 33% They need a lot of assistance for restructuring
