Development of biocrusts on temperate sand dunes and post-mining sites and their application in restoration ecology



Reclaimed post-mining sites undergo long time periods of succession. These initial soils, consisting of excavated and dumped material, are characterized by a high vulnerability to erosion, low water holding capacity, lack of nutrients, low pH or sparse vegetation. 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.
