The aim of Hamburg's landscape planning is to link parks, playgrounds and sports areas, allotment gardens and cemeteries through wide green corridors or narrower green connections to form a green network. So it should be possible to move undisturbed by road traffic on footpaths and bike paths in the countryside within the city and into the open countryside on the edge of the city. At the same time, the green network is an important part of the biotope network system.
