Methodology

The protected areas (NSG, LSG, GLB, ND) and their current states of processing are shown in terms of their spatial delimitations. Areas whose territories overlap are marked by a green boundary. At these points, the territories of the protected areas (for example, the "Wiesengrund - Meadow Hollow" NSG and the LSG "Niederungssystem des Neuenhagener Mühlenfliesses und seiner Vorfluter - Depression System of the Neuenhagen Mill Creek and its Precursors" in Brandenburg) overlap.

Berlin

In Berlin, the representation of the biotopes protected under § 30a NatSchGBln shows only the current state of the survey and constitutes no final statement or notice in any legal sense. There may exist additional areas not shown here, particularly on private property. In both Berlin and in Brandenburg, the protected biotopes within the NSGs, GLBs and NDs are not entered, because they are in most cases conterminous. For Berlin, no true-to-scale display was undertaken for the § 30a biotopes; rather, a labeling by symbols, which distinguishes between areas greater than 1 ha, 1 ha or smaller, and linear biotopes (e.g. reed-beds) was used.

The registration of the § 30a biotopes is based on the expert study "Definitions and Descriptions of Biotopes Protected under § 30a of the Berlin Conservation Law," commissioned by the State Commissioner for Conservation and Landscape Care (study group Hemeier and Steinlein 1995). The expert study gives an overview of the implementation of § 20c BNatSchG in the individual states (legal regulations, existing materials, features, minimal size), whereby Brandenburg is discussed in particular detail. It contains a general definition of the biotope types and concepts in § 30a NatSchGBln, and describes these briefly in terms of their structural condition, their site conditions and their characteristic vegetational formations. The emphasis lies on a floral-botanical characterization. The various forms, particularities and occurrences of the biotope types in Berlin are explained. The expert opinion further contains a mutual delimitation of the individual biotope types, so that a stand can be associated as clearly as possible with a concept according to § 30a NatSchGBln. An overview lists the plant associations occurring in Berlin by biotope type, in order to make possible an easier delimitation among the stands. In addition, indications are given on the significance of the biotope type for fauna, and exemplary occurrences in Berlin are cited. The rating criteria describe when and/or in which form a given area is protected under § 30a and/or which minimum condition must be fulfilled. Here, succession, degradation and regeneration stages are considered, although it should be considered that, in case of very rare or rare occurrence of an especially protected biotope type in Berlin, it is as a rule protected in any form. Greatly degenerated biotopes were not entered into the map, due to the rating criteria. Minimum sizes for biotope types, such as exist in other states, were not established.

On the basis of these substantial standards and evaluations of the substance of the above-mentioned statistical bases, an initial mapping of the § 30a biotopes was accomplished with the support of the State Commissioner for Conservation and Landscape Care, and checked with the borough conservation and green space agencies, the Berlin Forest Office and various conservationist organizations.

Brandenburg

In the spring of 1991, the registration of the ecologically valuable areas in Brandenburg was begun by means of a statewide selective biotope mapping. After the BbgNatSchG took effect, emphasis was placed of the mapping of the biotopes protected under § 32. The operational basis for the map-makers was an explicite mapping directive, with a description of the individual biotope types (Zimmermann 1994a). Presently, about 80% of the state area has been recorded by means of the selective biotope mapping. The data are stored at the Brandenburg State Environmental Protection Agency in the form of survey sheets for the biotope mapping, and of the biotope maps (scale 1:25,000). These constitute the list of the legally protected biotopes to be maintained by the LUA as per § 32 BbgNatSchG (biotope land-register), which are open to public examination. Since mid-1993, these data have been entered into an EDP-based biotope land-register (BIOKAT - the Biotope Survey and Evaluation Program). As a supplement to the selective biotope mapping, an overall biotope and utilization-type mapping based on CIR-aerial photography has been carried out in Brandenburg (Zimmermann 1994b). The biotopes legally protected under § 32 (and/or § 31) BbgNatSchG are for the most part shown with surface coloring on the map. The delimitations of the tree-lined avenues are entered roughly, and frequently include the roadways.
