updated: April 24, 2006 Technical Reference Our understanding of the biology, ecology and physiology of biological soil crusts has increased greatly in the past 10 years. Studies have been concentrated in Australia, Israel and the United States, but we have at least some information from sites around the world. There are now over 1,600 published studies on soil crusts. The attached PDF file is a 90-page report that summarizes our current state of knowledge about biological soil crusts, with emphasis on crusts found in the western United States. This report discusses distribution, biology, and the physiological functioning of crusts, as well as techniques for monitoring and managing this resource.
