Across the desert Southwest, ground void of plant material is prone to soil erosoin and dust storms. In this fallowed agricultural field, we see that a spring breeze can carry away fertile top soil and create air quality concerns.

Limited information is available about the movements of riverine smallmouth bass in landscapes with prevalent river-reservoir interfaces. This lack of information is especially problematic for the Neosho subspecies of smallmouth bass given the distribution covers an interwoven landscape of rivers and reservoirs.

An extremely rare Mojave River western pond turtle was recently observed by USGS scientists and staff from The Living Desert Zoo and Gardens in the Mojave Desert. Turtles of this population have rarely been seen since the late 1990s.
