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.

Page 2: Mississippi Delta Native Plants

• 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.

• 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.

• Native plants have many advantages over non-natives:

1. Tend to be disease resistant and require less maintenance (less fertilizer, less pesticide application)

2. Better adapted to local temperature and rainfall patterns

3. Generally non-invasive and don’t outcompete other species

Bald cypress - Taxodium distichum Bark Is red-brown, fibrous and stringyTrunk may swell at base and be surrounded by

"knees". Intermediate shade tolerance. The wood is decay resistant The seed is eaten by waterfowl.

‘Knees’ occur at the base of the tree

• 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.

Sweetgum - Liquidambar styraciflua Leaves are star-shaped and toothed.  Fruit is a spiny ball containing many capsulesSeeds are eaten by birds, ducks and squirrels

Red buckeye – Aesculus pavia• Understory shrub• Flowers are red, showy and attractive to hummingbirds

Page 17: Mississippi Delta Native Plants

Pecan - Carya illinoinensis • Naturalized in the southern U.S. and is intolerant of shade.• Heavy wood is used for handles and pulpwood• The pecan nut is known world wide

Page 18: Mississippi Delta Native Plants

Shagbark hickory – Carya ovata• Bark is smooth on young trees and dark gray breaking into

long loose strips on large trees.• Twigs are brown, stout and hairy  

Page 19: Mississippi Delta Native Plants

• 4-ribbed white nut is enclosed by a thick husk which is pale on the inside and splits to the base. 

• The hard wood is used for pulpwood, furniture and novelty items. 

• The nuts are eaten by many small animals.

Sugarberry - Celtis laevigata  • Leaves are simple, alternate, deciduous, and

ovate with toothed margins, long pointed apices and 3 main veins arising from the petiole.

• Twigs are thin and zigzag.  • Bark is gray and smooth with corky warts. 

• Fruit is a sweet, orange-red drupe.  • Usually found on moist sites in the southeast U.S.

and is tolerant of shade.  The wood is used for furniture and boxes, and the fruit is a favorite of birds.

American elm - Ulmus americana • Leaves are simple, alternate, deciduous, doubly

serrate, ovate, smooth to rough, up to 7 inches long and often with a greatly unequal leaf base. 

• Twigs are red-brown and mostly hairless with black-red striped ovoid buds. 

• Bark is gray with interlacing ridges and brown-white inner bark. 

• Fruit is a deeply notched, round and hairy samara. 

• The elms display a vase-shaped form.   • Its distribution was reduced by Dutch Elm disease.

Sassafras - Sassafras albidum • Flowers are yellow in early spring and the fruit is a dark

blue drupe on a red stalk.• Young twigs are mottled red, black, and green, pubescent

and aromatic. • Bark is dark green when young and brown-gray to red-

brown, thick and ridged on larger trees

Page 28: Mississippi Delta Native Plants

• The wood is used for fence posts and home-made fishing rods. 

• Oil of sassafras extracted from the roots is used in perfumes, tea and herbal remedies. 

• Many birds and mammals eat the fruit and bear and deer browse the foliage.

Sycamore - Platanus occidentalis • Bark is brown and peels to expose striking white inner

bark. Fruit is a round ball of achenes.• The trunk is often hollow, this species is a den tree for

wildlife.• Leaves - large, and with 3-5 roughly toothed lobes.
