Banner Marsh Habitat Rehabilitation and Enhancement Project

Rock Island District

Illinois River, Miles 138 - 144, Fulton and Peoria Counties, Illinois, Congressional District: IL - 17

  • Illinois Department of Natural Resources (ILDNR)

Description

Historically, the Illinois River Flyway has been one of the most important waterfowl migration routes throughout the United States. The bottomland lakes and marshes provided aquatic food plants and small animals like the fingernail clam that naturally attracted the migrating waterfowl. Banner Marsh has undergone a series of drastic physical changes, from bottomland lake and marsh to leveed agricultural lands and active mining operations, to a reclaimed strip mine. Valuable habitat important to the declining migratory waterfowl population has been lost.
