Pilot Project, Year 5<\/h1>\n

Testing the utility of biocrust restoration to stabilize soils and reduce Coccidioides<\/em> abundance<\/h2>\n

Valley Fever is a prevalent cause of community-acquired pneumonia in the southwestern United States. Infection is caused by inhalation of airborne Coccidioides spp. fungal conidia<\/em>. For most people, the disease is mild or asymptomatic, but in others, it can cause severe respiratory illness and even death. Native American and Hispanic people are more likely to have severe manifestations or die from the disease than Caucasians.<\/p>\n

\"\"<\/a>Although the cause of this disparity is unknown, it is likely a result of several factors, including work in agriculture, residence in areas experiencing land degradation and dust emissions, and inequity in healthcare.<\/p>\n

Soil becomes airborne in areas where the land surface has been disturbed, commonly as a result of agriculture, livestock grazing, recreation or land development. In the Southwest, a community of microorganisms called biocrusts are critical to maintaining soil health and integrity, but these organisms are also lost with soil disturbance. Biocrusts bind the soil surface, protecting it from wind and water erosion, thus reducing soil disturbance and dust.<\/p>\n
