這個國家公園和其他五大湖公園的困境，在美國國家公園保育協會（National Parks Conservation Association，簡稱NPCA）所作的一份新的報告中詳述。研究的公園涵蓋了美國全部4個湖岸。
Sleeping Bear Dunes National Lakeshore on Lake Michigan is in danger of being loved to death. High numbers of visitors are trampling down vegetation and erosion is occurring in high traffic areas. Water quality and the ecological integrity of Lake Michigan at the Dunes is in poor condition due to invasive species such as quagga and zebra mussels, which have taken over most of the lakebed.
The plight of this national park and that of five other Great Lakes parks are detailed in a new report by the National Parks Conservation Association, NPCA. The parks studied include all four of the U.S. national lakeshores.
"The parks support a variety of wildlife, provide abundant recreational opportunities, and help support regional economies, so it is crucial that we ensure they are well protected and get the funding that they need and deserve," said Lynn McClure, NPCA Midwest regional director.
According to NPCA's Center for State of the Parks report, the six Great Lakes parks face threats from air and water pollution, non-native species that are damaging ecosystems, adjacent development, and funding shortfalls that are threatening every aspect of the parks.
