Distinctiveness (1=highest,4=lowest): 3 (bioregionally outstanding)
This ecoregion is part of an important migratory bird flyway.  Bottomland hardwood forests were among the most interesting ecological communities in U.S., but nearly all in this region were destroyed.*

Conservation Status (1=most endangered, 5=most intact): 1 (critical)
About 5-9% of the habitat is not converted to agriculture and other uses.  Blocks of remaining habitat are in the wettest sites and are not representative of the ecoregion's major habitats.  Remaining blocks of habitat are fragmented and threatened by alteration of river flow and logging.*
