<br />at Lake McConaughy in western Nebraska (Rosche and Johnsgaard <br /> <br /> <br />, <br />1984) and on the Middle Loup and LOup rivers in central and <br /> <br /> <br />eastern Nebraska (R. Lock, ~epraska Game and Parks Commission). <br />.'.:.r.;,-",. <br /> <br />Breeding activity in Iowa bas occurred during the past five <br />years on ash ponds owned by rowa Public Service in Woodbury <br />County and by Iowa Power and Light in pottawattamie County along <br />the Missouri River (Wilson et al. 1983; D. Howell, Iowa Natural <br />Areas Inventory). Potential breeding habitat has been created at <br />DeSoto National Wildlife Refuge (Harrison County) but birds have <br />not yet nested there (G. Gagei De Soto National Wildlife Refuge1_ <br />Birds nesting at Lake of the Woods in Minnesota use habitat <br />similar to both prairie and Great Lakes areas. Currently, Piping <br />Plovers breed on state-owned sites on Pine and Curry Island, <br />Morris Point, Rocky Point, and Zippel Bay (Wiens and Cuthbert <br />1984, Wiens 1986, Haig and Oring 1987b). <br /> <br />Great Lakes Region: In Minnesota, a few pairs have been <br /> <br />known to breed annually at the Duluth Port Terminal in St. Louis <br /> <br /> <br />County (Niemi and Davis 1979, Davis 1985). Breeding activity in <br /> <br /> <br />Wisconsin is confined to Long Island in Lake Superior'S <br /> <br />Chequamegon Bay (Ashland Countx) (Matteson 1978, 1979, 1980, <br />1981, 1987). Here, success has been poor, and breeding have come <br />to an end due to vegetation encroachment andl1uman disturbance <br />(Matteson 1987). During the 19',85 field season, only one lone <br />adult was present. The only prpductive breeding populations <br />remaining on the Great Lakes are in northern Michigan. In 1986, <br />Michigan Department of Natural Resources surveys found breeding <br /> <br />14. <br /> <br /> <br />- <br />
