Invasive brush has closed in on the bluff along South Shore Dr. Neighbors are working to bring the skyline back into view for good.
Tell the parks, in your own words, why the bluff matters to you.

Once, this was the best view of Milwaukee, a true hidden gem. Today, invasive plants and overgrowth have hidden it away. Let’s bring it back.

These invasive species are taking over our bluff. Here's how to identify them and what Wisconsin law says about each.
Under Wis. Stat. 66.0407, anyone who owns or controls land must kill noxious weeds before they flower, by cutting or spraying. The law covers public land, including the county parkland here. Canada thistle is one of three named in the statute, and it is also Restricted under NR 40.
Wisconsin Statutes on Noxious weed species
Cirsium arvense
Spreads rapidly through underground roots, forming dense patches that crowd out native plants.
Without a state permit, you can't plant, share, sell or move these plants. Owning one is legal, and NR 40 doesn't require you to remove it. If you do, you can pull it up and haul it off for disposal, as long as no live seeds or roots get loose.
Wisconsin DNR on Restricted species
Robinia pseudoacacia
Fast-growing tree that forms dense thickets, blocking views and shading out native understory plants.

Campanula rapunculoides
Aggressive perennial that spreads through root fragments, difficult to remove once established.

Galeopsis tetrahit
Annual weed that competes aggressively with native plants for nutrients and space.

Lonicera spp.
Woody vine that climbs over and smothers native trees and shrubs, reducing biodiversity.

Ailanthus altissima
Fast-growing tree that sprouts from its roots into dense thickets, shading out native plants.

Morus alba
Produces abundant fruit that birds spread, leading to new invasive populations throughout the area.
Wisconsin's rule doesn't regulate these, so there are no permit requirements. They still crowd out native plants, and pulling them helps the bluff just as much.
Wisconsin DNR on Invasive species
Leonurus cardiaca
Perennial herb that spreads aggressively in disturbed soils and shaded areas.
We haven't confirmed these yet, but they're likely among the brush.
Rhamnus cathartica
Rapidly spreading shrub that alters soil chemistry and eliminates understory plants.
Rosa multiflora
Dense, thorny shrub that forms impenetrable thickets, crowding out native vegetation.

Join your neighbors for food, fun, and community! We'll be grilling hot dogs and celebrating together. Come learn about the Buff the Bluff initiative and how you can get involved.
This isn’t about demanding that the county fix the bluff. It’s about neighbors stepping up to do their part.
We’re raising funds so the people who love this view can help pay for restoring it, in part or, if we can, in full. The bluff is county parkland, so the county has to approve the work. But the cost doesn’t have to land on the county alone.
Every letter, sign and contribution shows the parks that this community is ready to work alongside them.
Three steps, in order of how much they help restore the bluff's natural beauty.
Tell the parks, in your own words, why restoring the bluff matters to you. This is the most helpful thing you can do.

The bluff has been Bay View's crown jewel for generations. Here's what longtime residents remember.
“This is my favorite view of Lake Michigan”
“This is the worst I’ve ever seen the bluff.”
