The Central Mixed-Grass Prairie extends from the edge of shortgrass prairie on the west to the beginning of tallgrass prairie and savanna-like habitat to the east. There are vast areas in this region converted extensively to agriculture as well as extensive areas of remaining high quality grassland in the Nebraska Sandhills and other sectors. The BCR includes some of the better remaining areas for Greater Prairie-Chicken and Dickcissel. Sandbars along the larger rivers host a large percentage of the continent's breeding Interior Least Terns. The region is an important spring migration area for American Avocet, Semipalmated Sandpiper, and Buff-breasted Sandpiper. Wetlands concentrated in the Rainwater Basin and other areas, such as Cheyenne Bottoms and Quivira, annually provide habitat for nearly 2 million ducks and 1 million geese. The mid-continent population of Northern Pintail and White-fronted Goose are particularly dependent on these wetland resources. However, wetland drainage and modification and sediment accumulation have jeopardized the integrity of these important landscape features. .
