Biological Soil Crusts

Biological soil crust probably isn't the first thing that springs to mind when snapping that photo of the Delicate Arch at Arches National Park. However, without the algae, mosses, cyanobacteria, and other tiny organisms that inhabit the surface of desert soils, places like Arches and other arid environments would be quite different. The US Geological Survey provides an online guide to biological soil crusts in this easy-to-navigate Web site. Crust 101 contains a detailed introduction to soil crust ecology, and the Advanced feature offers an extensive technical reference. The Web site also includes a photo gallery, list of related references, and a short list of links. This site is also reviewed in the November 27, 2002 Scout Report.
