Entisols are the typical sandhill soil, deep well-drained and nutrient poor. In Florida, sandhills receive 130 cm of rainfall per year, just like the more hydricecosystems surrounding them. Sandhills are xeric because they have poor water holding capacity.
Dominant vegetation includes longleaf pinePinus palustris, American turkey oakQuercus laevis, and wiregrassAristida stricta. A number of rare animals are typical of this habitat including the gopher tortoise Gopherus polyphemus, red-cockaded woodpecker Picoides borealis , Sherman's fox squirrelSciurus niger, and striped newtsNotophthalmus perstriatus. Invasive species that are a problem on sandhills include cogon grass, camphor trees, and Natal grass.
PHYSIOGRAPHY : The Nebraska sandhills are characterized by dune topography.
In the eastern portion of the Nebraska sandhills prairie, nondune soils are derived from glacial drift and loess; the drift consists of boulders, gravel, sand, and clay.
In the southwestern and western portion of the Nebraska sandhills prairie, sand sagebrush is an abundant shrub, associated with prairie sandreed and sand bluestem [47].
