The glacial history of the Great Lakes basin and the tremendous influence of the lakes themselves create unique conditions. These support a wealth of biological diversity, including many species and communities of global significance. The basin’s sand dunes, coastal marsh- es, rocky shorelines, lakeplain prairies, savannas, forests, fens and other landscapes contain features that are either unique to or are best represented with- in the Great Lakes basin. The remark- able biodiversity of the Great Lakes basin is illustrated by the Indiana Dunes National Lakeshore. This park ranks third among US. National Parks in plant diversity, yet its area is less than three percent of either of the top two, Great Smoky Mountains and Grand Canyon.
