Distinctiveness (1=highest,4=lowest): 4 (nationally important)
Although this ecoregion shares many of the species of surrounding ecoregions, it is unique due to the soil and surface characteristics caused by the irregular dunes and sandy soils.*

Conservation Status (1=most endangered, 5=most intact): 4 (relatively stable)
Because of the sandy soil, very little of this ecoregion has been plowed and it is about 85% intact.  Threats are degradation by overgrazing and toward the eastern end, development.*

Characteristic species*
Schizachyrium scoparium (little bluestem)
 Agropogon hallii (sand bluestem)
Stipa comata (needle-and-thread)
