Invasive species control is the targeted removal of non-native plants that threaten native ecosystems, property value, and land productivity. In central Wisconsin, common invasives include buckthorn, autumn olive, honeysuckle, and garlic mustard. Forestry mulching eliminates invasive growth mechanically — no chemicals required — and the mulch layer suppresses regrowth.

What We Do
About Invasive Species Control
Buckthorn is the big one in our area. It spreads fast, shades out everything underneath it, and changes the soil chemistry so native plants struggle to come back even after it's removed. We see it on properties all across Marquette, Adams, Waushara, and Columbia counties — woodlots, fence rows, field edges, lakeshores. Honeysuckle, autumn olive, and multiflora rose are right behind it. All four are listed under Wisconsin DNR NR 40 as regulated invasive species.
We remove invasives mechanically with a mulcher. The machine grinds the entire above-ground plant — trunk, branches, and all — into chips at ground level. The chip layer covers the disturbed soil and helps suppress re-sprouting. For properties with heavy infestations, we typically recommend a follow-up pass in year two to catch anything that comes back from the root system or seed bank.
We mechanically remove buckthorn, honeysuckle, autumn olive, and multiflora rose on properties across 8 counties in central Wisconsin. No herbicides required.

Why buckthorn is such a problem in Wisconsin
Buckthorn was brought to the Midwest as an ornamental hedge plant. It escaped cultivation decades ago and has been spreading ever since. It is so successful because it leafs out earlier than native species and holds its leaves later, giving it a competitive advantage for sunlight. It also produces enormous quantities of berries that birds spread across the landscape.
The deeper problem is what buckthorn does to the soil. It alters nitrogen cycling and changes the microbial community in ways that make it harder for native plants to grow back even after the buckthorn is gone. That is why the mulch layer matters — it covers the disturbed soil and creates a buffer while native seed stock recovers.
Both common buckthorn and glossy buckthorn are listed as restricted species under Wisconsin DNR NR 40, meaning it is illegal to transport, transfer, or introduce them. Removal is not just good land stewardship — for many properties, it is the responsible thing to do.
