Map Description

Tree Species Distribution, Total Area of the Berlin Forests

The distribution of tree species groups in the main stock of the Berlin forests shows the pine with 65 % and the oak with 13 %, while 11 % of the areas are stocked with birch and 4 % with beech. Hornbeam, maple, elm and other deciduous hardwoods account for 3 %, while fir, Douglas fir, larch and other conifers make up 4 % of the total area. Figure 2 and the corresponding Table show an overview of the distribution of tree species in the Berlin forests and the differences between the Forestry Agencies.

In the inventory layers Undergrowth and Secondary Growth, the distribution of tree species is completely different. Here, the area shares shift away from Pine (only 3 %) and Other Coniferous (2 %) to Deciduous Hardwoods (14 %), Oak and Beech (21 % each) and Deciduous Softwoods (39 %). The major share of the latter is accounted for by the black cherry, the common birch and the mountain ash. Among the Deciduous Hardwoods, the Norway maple and the sycamore dominate.

With a total of 10,500 hectares of undergrowth and secondary growth, as well as the staged character of the main stock which has been achieved to some extent, 50 % of the area of the Berlin forests now has a two or multi-layered inventory.

Age-Class Distribution, Total Area of the Berlin Forests

The age-class distribution shows a picture characteristic for the North German Plain. There is a clear excess of the third and fourth age-classes, which is due to over-exploitation during and after World War II. Except for these two age-classes, the age-class structure of the Berlin forests is quite well-balanced.

Clearly, the pine is the dominant tree species in all age-classes. Fortunately, there is also a share of oak in almost every age class.

An evaluation included all inventory layers in an age-class confirms the impression already obtained from the tree-species distribution that an extensive transformation in the inventory, involving a shift of considerable proportion away from pine monoculture and toward a mixed inventory with a major share of deciduous species, is occurring. In particular, the high proportion of oak and beech should be noted here. Less heartening is the large area share occupied by the ALn category (Other Deciduous with Low Rotation Times), since this essentially involves the black cherry.
