Biological soil crusts, or biocrusts, are complex communities of cyanobacteria, algae, lichens, bryophytes and other organisms living in association with the top millimeters of soil. Drylands encompass over 40% of terrestrial ecosystems and face significant anthropogenic degradation causing a loss of ecosystem integrity, services, and deterioration of social-ecological systems. To combat this degradation, some dryland restoration efforts have focused on the use of biocrusts to return many ecosystem functions and services. Authors introduce articles in the special issue that improve the state of current knowledge in biocrust restoration and highlight efforts to effectively restore biocrusts across different ecosystems, across scales, and utilizing a variety of lab and field methods.
