Cryptobiotic Soil Crusts, Colorado National Monument, Colorado, USA. Biological soil crusts are important components of desert ecosystems. They are a mix of organisms and their metabolic byproducts, including cyanobacteria, bacteria, liverworts, green and brown algaes, lichens and fungi. They help plants by stabilizing sand and dirt, preventing erosion, retaining water, and fixing atmospheric nitrogen. | |
