Two Rivers National Wildlife Refuge was established in 1958 to protect and enhance habitat for migratory birds. Located between the Mississippi River and Illinois River, the refuge encompasses 9,225 acres of riverine and floodplain habitat scattered around the confluence of the rivers. The mosaic of wetlands, open water, bottomland forests and prairies provide habitat for numerous mammals, amphibians, reptiles, fish, nearly three hundred bird species, and a population of decurrent false aster, a Federally threatened plant species.

Please use caution when visiting the refuge and pay attention to signs.  If you see water over a road or trail, turn around and do not drive or walk through it.

      Public Comment Period for Aerial Spraying Environmental Assessment

      The U.S. Fish and Wildlife Service is seeking public review and comments regarding a draft environmental assessment for continuing aerial herbicide application at Two Rivers National Wildlife Refuge. The refuge has historically implemented aerial herbicide application as part of integrated pest management efforts. 

      The primary need for aerial herbicide application is to reduce and control dense populations of invasive and undesirable plant species, to set back succession in areas where prescribed fire or ground application of herbicides is not practical or cannot be conducted on a frequent basis, and to maintain refuge facilities and infrastructure, thus fulfilling the mission of the National Wildlife Refuge System, as outlined by the National Wildlife Refuge System Administration Act (NWRSAA), as amended by the National Wildlife Refuge System Improvement Act (16 U.S.C. 668dd et seq.) “... to administer a national network of lands and waters for the conservation, management and, where appropriate, restoration of the fish, wildlife, and plant resources and their habitats within the United States for the benefit of present and future generations of Americans.” The draft environmental assessment reviews two alternative approaches for herbicide application on the refuge: the preferred alternative of taking no action and continuing current management efforts that include aerial herbicide application, and ending all aerial herbicide application on the refuge but using other invasive species invasive species
      An invasive species is any plant or animal that has spread or been introduced into a new area where they are, or could, cause harm to the environment, economy, or human, animal, or plant health. Their unwelcome presence can destroy ecosystems and cost millions of dollars.
