WEST TENNESSEE WEST TENNESSEE Mississippi Alluvial Plain, Coastal Plain, Mississippi Alluvial Plain, Coastal Plain, and West Tennessee Uplands and West Tennessee Uplands West Tennessee comprises the Mississippi Alluvial Plain, Coastal Plain, and West Tennessee Uplands. This region is often referred to as the Gulf Coastal Plain because it was submerged between 40-70 million years ago by the Gulf Coastal Embayment. Site conditions within the region are determined by topography, soil pH, soil depth, aspect, availability of light, and hydrology. These site con- ditions support a mosaic of native plant communities. ➤ Inundated tupelo, cypress-tupelo, and scrub-shrub swamps. ➤ Oak dominated alluvial bottomland hardwood forests. ➤ Mixed mesophytic forests on slopes and ravines char- acteristic of the Chickasaw Bluffs. ➤ Open canopy forests associated with warm season grass barrens. ➤ Upland oak-hickory forests ranging from basic soil types to heath-shrub dominated types.

Hydric soil occurs in the flood- plains along all the major rivers that drain the Gulf Coastal Plain. A fine particled clayey gumbo interspersed with LANDSCAPING sandy soils occurs along the Mississippi, while a friable silty loam occurs along smaller rivers, streams, and creeks. WITH The Coastal Plain is a gentle sloping plateau that begins where the Chickasaw Bluffs rise above the Mississippi NATIVE Alluvial Plain and extends to the West Tennessee Up- lands. The Coastal Plain is formed from finely ground wind-blown loess material derived from retreating PLANTS northern glaciers. The flat to rolling topography is caused by the wind-blown loess that covers the sand, PROMOTES BIODIVERSITY silt, and clay deposited by the Coastal Embayment. The West Tennessee Uplands is formed from the sand, and endorses a land ethic that silt, and clay deposits that underlay the Mississippi Al- celebrates our natural heritage luvial Plain and the Coastal Plain. Soils vary from clay to sandy. The site conditions of the Western Valley, contigu- ous to the West Tennessee Uplands, are similar to the Western Highland Rim of Middle Tennessee.

Basics about using natives When landscaping with natives match the right plants with the right site conditions. Consider using plants that occur together in their natural habitats. Do your homework before planting; study the plants and the site con dition information in this brochure. Visit a natural area and observe how plants occur and design your landscape accordingly. Buy nursery propagated plants. Remember, landscaping with natives is art imitating nature.
