Mississippi Delta Native Plants

1. Mississippi Delta Native Plants • Previously, river swamps represented this part of the central United States. • The trees could survive in areas that flooded or were covered with water for part of the year.

2. Two hundred years ago, bottomland forests covered almost thirty million acres across the Southeastern United States. • Today, only 40% of this area supports these type of habitat. • These native plants provide food source for birds, insects, and other native wildlife.

4. Mississippi Flyway, a bird migration route utilized by migratory waterfowl, songbirds, and shorebirds. • The flyway is predominantly used by these birds for food, water, and shelter. • Agriculture and urban development have eliminated most native plant communities through forest clearing. • The introduction of exotic and invasive plants have replaced many natives. • One goal is to restore native habitat to help migratory wildlife and enhance their food availability.

5. Native plants have many advantages over non-natives: • Tend to be disease resistant and require less maintenance (less fertilizer, less pesticide application) • Better adapted to local temperature and rainfall patterns • Generally non-invasive and don’t outcompete other species

6. Bald cypress - Taxodium distichum Bark Is red-brown, fibrous and stringy Trunk may swell at base and be surrounded by "knees". Intermediate shade tolerance. The wood is decay resistant The seed is eaten by waterfowl.

7. ‘Knees’ occur at the base of the tree

8. Oaks, beeches, and hickories are considered to be mast trees – produce lots of food for wildlife • White-tailed deer, raccoon, squirrels, chipmunks, opossum, mice , fox. turkey and quail.
