Land Cover of the Lower Mississippi Valley
The Lower Mississippi Valley collects most of the streamflow of the 48
states. This narrow outlet between (worn) mountain blocks,
sediment-filled and planed flat by millions of years of river
meandering, is the Mississippi Delta. This area is considered “the best farmland this side of
the River Nile”, comparable in size, shape, and agricultural
significance to California’s Central Valley.
The uplands on either side
are a mixed forest, grassland, and farmland mix. An exception is the
large mostly evergreen forest just west of the Delta, between the
Arkansas and the Red.
The map includes all of Louisiana, Arkansas, Mississippi, and Alabama;
most of Missouri, Kentucky, and Tennessee, and easternmost Texas,
Oklahoma, and Kansas as well as southern portions of Illinois and
Indiana, western Georgia, and most of the Florida Panhandle.
