Berlin´s landscape program formulates basic goals and measures to promote high quality urban development with respect to the ecosystem, protection of biotopes and species, the appearance of the landscape, and recreational use.

In the city center, using the “biotope area factor” (BAF) makes a particular approach to securing “green qualities” possible. In Berlin it can be established in landscape plans as an ordinance.

The BAF covers the urban forms of use residential, commercial and infrastructure and formulates ecological minimum standards for structural changes and new construction. All greening potentials such as courtyards, roofs, walls and fire walls are included. More information

The BAF expresses the ratio of the ecologically effective surface area to the total land area. More information

Each plot of land can be designed in various ways. In principle, measures that lead to an expansion of the area of vegetation on the ground are given priority. Only then should additional possibilities, such as the replacement of asphalt and concrete with other surfaces, be utilized. More information
