“Introduction Bare ground is not just Pyruvate dehydrogenase abiotic ground; in fact, the soil surface in areas free of higher vegetation is often covered by a skin made up of a community of microorganisms, like cyanobacteria, algae, lichens and bryophytes—forming a complex structure known as biological soil crust (BSC). Biological soil crusts can be the only vegetation cover in arid and semi-arid regions such as hot and cold deserts or xerothermic steppe vegetation (Belnap and Lange 2003). They are also the first colonizers of disturbed soils and have major impacts on the soil properties through stabilization, erosion limitation, and facilitation of colonization by higher plants (Malam 1998; Belnap et al. 2003b; Thomas and Dougill 2007; Guo et al. 2008). Despite these immensely important properties, soil crusts are neither well understood nor well appreciated by conservation and regulation authorities who are missing opportunities for improved policies and actions in the area of land protection. Yet they are the natural and most effective force in land stabilization and recovery (Campbell 1979; Campbell et al. 1989; Belnap et al. 2003a).
