Distinctiveness (1=highest,4=lowest): 2 (regionally outstanding)
The diversity of soil types in the ecoregion produces a greater community diversity than that of tallgrass prairies further north.*

Conservation Status (1=most endangered, 5=most intact): 2 (endangered)
Less than 1% of the original vegetation remains.  Cultivation and urbanization are major threats.  Some habitat remains in areas used for hay production.*
