The goal of the two-year project is to manage stormwater runoff, control erosion and reduce pollutants to Lake Michigan through the restoration of native habitat and stabilization of the beach dunes. This work will also improve coastal resilience while supporting migratory bird and butterfly populations.
Coastal resilience means landforms and plant communities on the shore can bounce back from extreme weather with minimal damage. Wind and rain, especially during heavy storms, was loose sediment and road pollutants into nearby waterways. This negatively impacts water quality and smothers aquatic life. Dune and back dune plant communities will be revitalized with new shrubs, trees and forbs to diversify vegetation, add habitat and increase rainwater absorption.
The top of the bluff is marked by open prairie comprised of grasses and perennial wildflowers. Selective management of aggressive and invasive species will allow the additional plantings of native prairie forbs and grasses. Native plants have strong, deep roots that form an extensive fibrous network which prevents erosion, protects habitat, and helps filter pollutants. Healthy native ecosystems ensure the bluff and dunes can weather whatever storms Lake Michigan throws at it. As many well know, Atwater is a sanctuary for native wildlife. Over 14 species of shorebirds call the shores of Lake Michigan home, and some 300 species of migratory birds fly through Milwaukee every year. High quality habitat along the lake helps to ensure the health of these migratory populations. Bald eagles have also been recently spotted at Atwater Beach, nesting on the nearby bluffs. Over 400 species of native bees as well as migrating butterflies, such as Monarchs, rely on native plants for food and shelter.
This project will add trees, shrubs, and herbaceous plants specifically chosen to manage erosion and precipitation, diversify and strengthen existing plant communities and support wildlife. Whether for swimming, exercising, playing in the sand, appreciating wildlife, or just enjoying the scenery, Atwater Beach has played a central role in the community of Shorewood for over 100 years – and will remain so for decades to come!
