Some 56,000 ha of the entire urban area are covered with vegetation. For a total area of about 89,100 ha, this corresponds to a percentage of approx. 63 %. It is important to note here that the vegetation is analysed in plan view, due to the use of remote sensing data. This means that areas covered with vegetation also include areas that are impervious underneath the vegetation cover, e.g. yards that are covered with trees but are largely paved. Areas covered with vegetation are therefore not the same as vegetated soil.
A comparison with the area sizes of those block (segment) areas that have been categorised as purely green and open space use in the Urban and Environmental Information System (ISU) (Map “Inventory of Green and Open Spaces” (06.02), Tab 2, SenStadtWohn 2020b) shows that about 19,000 ha of vegetated areas are located outside the “traditional” green spaces, i.e. on road areas and in areas associated with structural uses. This accounts for roughly 54% of the total of 35,000 ha of green and open spaces according to the 2020 ISU and illustrates the substantial resources of urban green space in Berlin’s residential areas, but also in other built-up areas of the city.
Comparing the absolute sizes of areas covered with vegetation in the 12 boroughs of Berlin, it is evident that the largest such areas are also found in the boroughs with the largest total area that are located outside the City Rail Circle Line. These boroughs contain large forest areas, e.g. the Köpenicker Forst in Treptow-Köpenick, the Bucher Forst in Pankow, the Spandauer Forst in Spandau, the Tegeler Forst in Reinickendorf and the Grunewald in Steglitz-Zehlendorf and Charlottenburg-Wilmersdorf (cf. Figure 7, sorted according to the borough numbering system based on the Verwaltungsgliederung (administrative division) of Berlin.).
