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!).

Increasing frequency of Phoenix dust storms
A video plucked from the web from a Phoenix NBS Channel 12 news program... They mention increasing frequency of dust storms. Also at one point there is a mention of at least one dust source north of Tuscon. What they don't mention is that there is considerable agriculture and abandoned agriculture in that area(spurred by wartime cotton demand. I don't know if Phoenix's dust comes from these areas but it seems like a likely candidate. The news program seems to lay the blame for increasing dust storms at the feet of drought, which is one key driver, but never suggests that there is a human land use component to this phenomenon.
