Technical Abstract: Native plant communities throughout the Southwestern United States are subject to increased abiotic stress due to climate change. As native grass cover is replaced by shrubs, more bare soil surface is susceptible to erosion by wind. The dust record for the last 20 years indicates that wind erosion and resultant fugitive dust emissions are increasing over broad areas of the Southwest. We used a Portable In-Situ Wind Erosion Laboratory (PI-SWERL) and a simple pneumatic gun method to assess and compare the erodibility and dust emissions from multiple undisturbed and disturbed soil surfaces in Texas, New Mexico, and Arizona. Results of this study will be presented along with recommendations for improved management of these changing ecosystems.
