The Sandsage Prairie ecoregions landscape is composed of low, rolling dunes and stream breaks in a four county area in southwest Nebraska. While mixed-grass prairies occur on the breaks and bluffs of the Republican and Frenchman Rivers, Sandsage Prairie occurs on rolling sand dunes. The prairies are fragmented by center pivot development. This ecosystem is significant because it contains some of the highest quality loess mixed-grass prairies in the state. Due to the lowering of the groundwater table the lakes and wetlands in this ecoregion have all but disappeared.
