Habitat types and landscapes

In contrast to other shell limestone areas in Germany, Bliesgau evinces a clearly differentiated geomorphological structure. This leads to starkly different micro-climates in connection with the different forms of land use at different locations. This means that there are widely varying living conditions in a tight space, which enables various ecosystem types to exist within a limited space. The area observed thus includes both species whose primary range of distribution is in the Mediterranean as well as those with a continental or Atlantic range of distribution.

The Biosphere Reserve Bliesgau can be generally broken down into the south, characterised by open land shaped by shell limestone, and the much more heavily forested variegated limestone of the north. But within the two sub-areas there are remarkable differences in the landscape that are the result of natural processes and human development.

The area is also shaped by the Blies and its valley with its extensive flood plains. It is characterised by a variation between large areas of cultivated fields and meadows, reed beds, tall forb fields and forested meadows.
