Learn about the potential uses of biological soil crust sods (biocrust sods) for degraded soils restoration and as fire and fuel breaks in desert environments.
Biocrust sods (portable islands of lichens, mosses, cyanobacteria, and other organisms that form the cohesive soil communities known as biological soil crusts) are a novel technique for restoring critical soil systems in degraded landscapes. Because biocrusts can suppress the emergence of exotic plants, biocrust sods may also serve as living, ecologically beneficial fuel breaks in regions where the grass-fire cycle is driving more frequent fires. This presentation will offer preliminary results from studies in the Sonoran and Mojave deserts, where researchers have been testing the capabilities of these new restoration tools. Anyone interested in soil ecology, restoration, or fire will leave this presentation with a new appreciation for biocrusts and their potential as critical restoration partners in two American deserts.
