Lower Mississippi

Help Us Protect the Lower Mississippi River Valley

The mighty Mississippi is America’s longest and most famous river, and its southern floodplain is also a place of superlatives. With its rich soils, seasonal flooding and long growing season, the Lower Mississippi Alluvial Plain is exceptionally rich and diverse. This region is known as a sportsmen’s paradise for its abundance of wintering waterfowl and game, but it also harbors a variety of endangered aquatic species and shelters a vast numbers of migratory songbirds.

Several national wildlife refuges are located on the lower Mississippi and its tributaries, including Cache River and White River refuges in Arkansas and Tensas River refuge in Louisiana.

Significance and Threats

The wetlands of the Lower Mississippi support millions of wintering waterfowl and draw hunters from around the world. Less famous, but no less important, are the bottomland hardwood forests of this region, which provide crucial migratory and nesting habitat to declining bird species such as Swainson’s warbler, wood thrush, swallow-tailed kite and possibly the elusive ivory-billed woodpecker. This landscape is also the last stronghold for the Louisiana black bear, an endangered subspecies of the American black bear numbering about 100.

As with other areas along this storied river, the Lower Mississippi Valley has been dramatically altered by humans. Two centuries ago, this region was covered with 24 million acres of bottomland hardwood and swamp forests. Today, more than 80 percent of these forests have been fragmented by development or converted to farmland. The river and its tributaries have been dammed, diverted and diked, leaving some forests dry and others flooded. Pesticides, fertilizers and other chemicals have polluted the waters. All of these changes have taken a huge toll on fish and wildlife.

What NWRA is doing

To safeguard the wildlife of the Lower Mississippi, NWRA worked with the a diverse group of partners to identify key landscapes for protection and restoration. NWRA is now working with these partners to:

  • Help acquire and restore crucial wildlife habitat at Cache River and White River refuges in Arkansas;
  • Support planning, community outreach and expansion efforts at Tensas River refuge in Louisiana;
  • Identify and restore important habitat in the Atchafalaya Basin and southeast Louisiana.
