305 WINDMILL & COTTONWOOD
Nebraska Sandhills. Located primarily in north-central Nebraska, the sandhills are comprised of sandy soil and irregular dunes, some reaching as high as 330 feet in height. As much as 85% of the sandhills remains intact and unplowed and only drought resistent vegetation, such as bluestem and other grasses, can survive in the sandy soil. The sandhills sit atop the massive Ogallala Aquifer, and marshes and temporary and permanent shallow lakes and wetlands are common in low-lying areas. This provides vital habitat for more than 300 species of animals, fish, and birds. Until the 1870s, the sandhills were inhabited by large populations of bison. Today they are among the most productive cattle ranching areas in the world, supporting over 530,000 beef cattle.
