Marram Grass Builds Sand Dunes

In West Michigan the wind and waves have built sand dunes. Some of the best dunes on the planet are found there. Marram grasses hold the dunes together.  Their roots weave a network of webs under the sand that keeps the sand from escaping.  Pictured is marram grass but there are other types of grasses.

Read more about sand dunes along the Great Lakes in my book, The Dynamic Great Lakes.
