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
(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.*
