Nebraska Sand Hills Mixed Grasslands
Sand Hills east of Valentine, Nebraska (c) 2008 Steven J. Baskauf
Source of bioregions data: Olson, D. M. and E. Dinerstein. The Global 200: Priority ecoregions for global conservation. (PDF file) Annals of the Missouri Botanical Garden 89:125-126.
Distinctiveness (1=highest,4=lowest): 4
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.*
