I was wondering if land that is preserved, is claimed completly unsusable, or if the city has the right to add a few benches and use it as park space, or an urban open space. I am just asking because there is some green spaces in my city that are preserved because they contain a rare species of trees, but when i pass through there I always think that it spacious and beautiful, and that it woud make a nice park while using the natural landscape of the land.
