IOWA 



General description: The wetlands of Iowa are found on the bottomlands along 

 the Missouri (Forney's Lake), Mississippi, and other rivers (Bergo's Slough), 

 and in poorly-drained sloughs and potholes in the northern glaciated section of 

 the state (Anderson Goose Lake, Dewey's Pasture). 



Status of the wetlands: Many of the sloughs and potholes have been destroyed 

 by agricultural practices. Some of the best wetlands are being manipulated for 

 waterfowl production. 



Sources of data: Data were provided by state personnel, university biologists, 

 and the Regional Director of The Nature Conservancy. 



Recommendations: Top priority should be given to the Dewey's Pasture — 

 Smith's Slough area as a Natural Landmark. It is outstanding, both from the 

 point of view of quality and the extent to which it has been studied. National 

 recognition would increase the probability that the State Conservation Commis- 

 sion would continue its present policy of treating this wetland as a Natural Area. 

 Anderson Goose Lake is privately owned. Whether the present management 

 would be compatible with landmark status would have to be determined. 

 Bergo's Slough, Rush Lake, and Forney's Lake are all state-owned. They are all 

 reported to be excellent wetlands, rich in wildlife. The question as to whether 

 present public hunting policies are compatible with landmark status should be 

 determined.
