A networking resource devoted to biological soil crusts and the researchers who study them. We will provide a means for international scientists to communicate, share their research, share important news and announcements, ask questions and find collaborators. We will also provide a space for informal writing on research, opinion, and ideas (now seeking posters!).

Tiny forests in the Utah desert
Mi amiga Sasha Reed on a short PRX radio piece by Jennifer Jarret about biological crusts, dust, etc. Piece Description From Arches National Park, we get a close-up view of a living groundcover called "biological soil crust." This groundcover, made up of tiny organisms like mosses, lichens and cyanobacteria, helps to stablize the soil surface; "holding the place in place." It is extremely resilient to wind and water, but particularly sensitive to compressive forces like stepping or driving on the crust. Once disturbed by these kinds of compressive forces, the soil -- the place -- can start to blow away. This kind of destruction is not unike deforestation; just...smaller. Listen as Dr. Sasha Reed, a research ecologist with the U.S. Geological Survey, explains why seemingly localized impacts to Utah's crust communities have much greater implications for the western U.S. Reed was awarded the Presidentai Early Career Award for Scientists and Engineers in 2011.
