Jim Ketelsen Greenwing Marsh

The Jim Ketelsen Greenwing Marsh is a 68-acre tract with a native prairie pothole and a restored wetland, restored and native prairie, pasture grasses, a sedge meadow, and a shelterbelt. The marsh is a memorial to honor the late Jim Ketelsen, an avid outdoorsperson and supporter of the Ducks Unlimited Greenwing program. He died while hunting ducks along the Des Moines River.  

The area was acquired by the conservation board in 1987. The acquisition was made possible through the partnership of several agencies: Ames Chapter of the Izaak Walton League, Anderson Lake Sportsmen, Inc., Big Bluestem Audubon Society, friends and family of Jim Ketelsen, Iowa Department of Natural Resources, Habitat Stamp Grant program, Dr. Gerald Johnson, Story County Pheasants Forever, and Iowa Natural Heritage Foundation Wetlands for Iowa Program.

The marsh is a public hunting area. Hunting and trapping are allowed.  No target practice is allowed. Only non-toxic ammunition is allowed.

Hiking, walking, bird watching, geocaching, and several other activities are possible however we do not maintain trails nor do we have picnic tables or grills available.
