If you’ve spent much time in the desert, you’ve probably seen the signs; “Don’t Bust the Crust!” These warnings for biological soil crusts refer to a specialized community of mosses, lichens and cyanobacteria that prevent dust erosion and capture nitrogen from the air for plant communities to use. Fire in deserts are changing these communities … killing the cyanobacteria, and allowing another, less useful bacteria to establish — Firmicutes. See fact sheet here.
