Development of biocrusts at restored post-mining sites in Brandenburg 


Stress tolerant microorganisms colonize the new soil surface in reclaimed areas. On the upper few millimeters of the topsoil they are forming a biological soil crust (biocrust); containing cyanobacteria, bacteria, green algae, mosses, lichens and fungi, which crosslink soil particles.

The compositional structures of biological soil crusts at various developmental stages and their photosynthetic properties were investigated on former open-cast lignite sites, currently under reclamation, an artificial sand dune in Welzow Süd, and a forest plantation in Schlabendorf Süd (Brandenburg, Germany). As development of biological soil crusts progressed, their contents of organic carbon and total chlorophyll increased. The ratio of these parameters, however, varied with the relative contribution of lichens and mosses in particular.
