Abstract:

Introduction to Microbiotic Crusts provides information on a soil associated component of many plant communities that has not been widely recognized or characterized. The majority of the research on these crusts is limited to the Great Basin and Colorado Plateau regions of the United States. There is validity in generalizing the basic functions of the crusts to wherever crusts are found, given that their gross compositions are similar (cyanobacteria, algae, mosses, lichens, etc.). However, it would not be valid to estimate the general importance of these functions in other regions because species composition does differ between crusts, particularly within the larger components (i.e., lichens, mosses). <br> This document was written by Roxanna Johnston, botanist, and includes the comments of numerous reviewers.
