Habitat Restoration

The Mississippi River, the third largest river in the world, is home to approximately 241 fish species, 50 mammal species, 45 reptile and amphibian species, and 37 species of mussels.  Sixty percent of the nation’s migratory birds occupy the Mississippi Flyway. More than 14 million ducks pass over this floodplain twice annually.

In order for our river ecosystem to function properly, riparian lands must remain natural and floodable.
