Take cues from nature to bring wildlife to your lake’s shoreline

Oakland County has some of the most stunning inland lakes Michigan has to offer and attracts those seeking their tranquility, stunning views and countless recreational opportunities, including boating, kayaking, swimming and fishing. Lakes also support an abundance of wildlife that not only help enhance lake health, but also give us one more reason to love Oakland County lakes.

WILDLIFE DEPENDS ON NATURAL SHORELINES TO PROVIDE CRITICAL HABITAT

The shoreline is one of the key components of a lake responsible for sustaining wildlife. Shorelines serve as a natural transition zone between land and water, providing critical access and habitat for lake life. For example, fish breed and find food necessary for survival and growth in this area. This is also where many animals who live on land interact with lakes. There is no doubt that the diversity, health and stability of this area is essential to the animals that live in lakes.

NATIVE PLANTS HELP MAINTAIN HEALTHY LAKES WHILE ATTRACTING BEAUTIFUL AND BENEFICIAL INSECTS

Native shoreline plants grow in, along and just outside of the water and are adapted to local conditions. They support beneficial insects including natural enemies that help control pest populations. They also support native pollinators like Monarchs. Trees, shrubs and other native plants hold the shoreline in place with their deep roots and guard the land from waves produced by wind and boats with their stems. The vegetation also acts as a buffer, capturing nutrients and runoff from the land above the lakeshore.

NATURAL SHORELINES MAKE WATERFOWL THINK TWICE BEFORE CHOOSING TO STOP

Canada geese love lawns that go right to the water’s edge so they can safely graze and rear their young. Maintaining taller vegetation at the shoreline discourages geese and other waterfowl because it prevents them from seeing predators. Joe Nohner, inland lakes habitat analyst for the Michigan Department of Natural Resources, and coordinator for the Midwest Glacial Lakes Partnership, said, “A natural shoreline helps to address the goose problem which also helps to address nutrient runoff issues and provide habitat for fish, frogs, birds and other species.”

DOES YOUR SHORELINE PASS THE REPTILE AND AMPHIBIAN TEST?

Shorelines with grass to the water’s edge or with a seawall do not fully support fish and wildlife due to habitat removal and destruction. One reptile, the Blanding’s turtle, depends on natural shorelines. They move between water and land during different parts of their lifecycle. Seawalls can prevent the Blanding’s as well as other turtles from accessing the land to lay eggs.

Amphibians such as frogs and toads require natural shoreline habitat as well. While toads live on land they are tied to the water for reproduction. Green frogs simply cannot survive without shoreline plants. Frogs and toads are also important predators, consuming thousands of insects. In turn, frogs and toads are eaten by other animals including fish, birds, mammals and reptiles.

STEPS YOU CAN TAKE TO SUPPORT WILDLIFE ALONG YOUR SHORELINE

Do you want to bring more wildlife to your waterfront? Plant it, and they will come. Here are some things to consider:

• Identify barriers to wildlife. Seawalls and rock riprap create vertical or semi-vertical barriers and disrupt

the natural transition between the water and land. Many animals need to be able to move back and forth to feed, rest and nest. If a tree falls into the lake, consider keeping it there to provide excellent fish and wildlife habitat. Or, consider adding an access structure ramp or platform steps to your shoreline. You can also add plants in front of a seawall and directly into riprap.

• Rethink landscaping with habitat in mind. Replace some shoreline lawn with native plants that provide food and protection. Instead of removing aquatic plants from the lake, preserve as many as possible to protect your lake’s health. If you desire to see Monarch butterflies at your lakefront, include milkweed in your plant palette to support its caterpillar stage. If you are worried about creating a “wild” shoreline, note that native plants also thrive in more well-ordered gardens.
