Bare Ground = Blowing Dust
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.

Assessing the spawning movement and habitat needs in Utah
Assessing the spawning movement and habitat needs in UtahLimited 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.
