Shoreline - Landscaping

Living on the water offers scenic views and recreational opportunities. Algae-filled water and closed beaches destroy these desired amenities, and can be dangerous to both human and ecosystem health! Many lawn care activities can contribute to unsightly and hazardous water bodies.

Algae is fed by grass clippings, leaves, eroding soils, garden fertilizers and other chemicals sprayed on lawns and plants. An increase in large algae blooms blocks sunlight, causing rapid plant death. Bacteria then step in to decompose the remains, removing oxygen and releasing carbon dioxide in the process. The lack of oxygen kills any species that cannot escape the dead zone. Goodbye fishing, swimming and pretty views!

Shoreline Without Vegetative Buffer

Shoreline with Vegetated Buffer

It may seem odd that natural grass clippings, fall leaves, and eroding soil would be harmful to water bodies. However, never in history has there been so many impervious surfaces that allow stormwater to quickly move across landscapes, pick up surface pollutants and move them into nearby water bodies.

Luckily, there are easy ways to manage landscapes on the water’s edge that enhance the view and maintain the health of your waterbody! 

Shoreline Landscaping Tips

  • Plant a Vegetated Buffer: Maintain a vegetated buffer of native plants along the waterway to prevent grass clippings, fall leaves, and other pollutants from quickly and easily entering water bodies. 

  • Choose Natives Whenever Possible: Wisconsin native plants have longer and more fibrous root systems than turf and horticultural plants which prevents erosion.

  • Reduce Fertilizing: Reduce the need for fertilizers by checking soil needs before applying, and opting for native plants that are resilient in Wisconsin soils. If using, refrain from applying before rain events to prevent waste and runoff pollution.

  • Perform Proper Mowing: Direct mowers away from water bodies and refrain from mowing up to the water’s edge. Taller vegetation also prevents geese whose waste contributes algae-feeding nutrients and harmful E.coli to the water.
