Michigan’s sand dunes face serious threats as climate change and environmental factors continue to evolve, as do the communities surrounding them, experts say.
Lake Michigan communities have seen problems in recent years as a result of sand dunes shifting, said Emily Smith, the land and water conservation policy manager at the Michigan Environmental Council.
“Sand dunes are already extremely unique in Michigan,” Smith said. “We have globally rare ecosystems here. They are ever-changing because it’s sand and blows around.”
Smith said Lake Michigan’s coast has a greater concentration of sand dunes than the other Great Lakes.
According to the National Park Service, these dune habitats on Great Lakes coastlines are fragile.
“From climate change, we get more extreme weather on our Great Lakes coasts and higher wave action from that weather, which increases the erosion on the lakeshore,” Smith said.
The effects of climate change can be seen at all the Great Lakes, but Lake Michigan has seen more frequent erosion and high water events along its shore.
