Invasive Species Removal
in Ohio

What This Looks Like

Dense thickets you can't walk through — especially in fence rows, forest edges, and areas that don't get regular mowing. The understory has been completely taken over: where you used to see native wildflowers and grass, there's nothing but honeysuckle, rose canes, and olive shoots.

In fall, the signs are unmistakable. Bush honeysuckle holds its green leaves weeks after native trees have dropped theirs. You can see the invasion mapped out across your property in November — every green patch is honeysuckle. In spring, berries from last season's crop are already germinating, spreading the problem into areas that were clear last year.

What Causes It

Ohio's invasive species problem is ecological, not just cosmetic. These plants outcompete native species and accelerate once established:

1. 1Bush honeysuckle (Amur and Morrow varieties). Ohio's number one invasive. Each plant produces hundreds of berries that birds eat and deposit across your property — and your neighbors'. It leafs out earlier than native plants, shading them out before they can photosynthesize, and stays green later in fall. A single unmanaged plant can colonize a quarter acre in three years.
2. 2Multiflora rose. Originally planted for erosion control and livestock fencing, it escaped cultivation decades ago. Each plant produces thousands of thorny canes that arch outward and root where they touch the ground, forming impenetrable barriers. A single plant can cover 100 square feet in a season, and the thorns make manual removal painful and slow.
3. 3Autumn olive and Bradford pear. Both were widely planted as ornamentals before their invasive nature was understood. Autumn olive fixes nitrogen, altering soil chemistry in ways that favor more invasives over natives. Bradford pear cross-pollinates with wild callery pear, producing thorny offspring that colonize abandoned fields and forest edges rapidly.

Realistic DIY Assessment

Manual pulling works for individual honeysuckle plants under 2 inches in diameter, especially in loose or wet soil. For small patches — a dozen plants or fewer — this is effective and satisfying work. Pull the entire root ball, don't just snap the stem.

Chemical treatment is the standard forestry approach for scattered plants. Cut the stem close to the ground and apply concentrated glyphosate or triclopyr to the fresh stump within 15 minutes. This kills the root system. It's effective but labor-intensive for large areas — you're cutting and treating each plant individually. For a half-acre honeysuckle thicket with hundreds of stems, the cut-and-treat method could take 40+ hours.

How We Eliminate Invasives

Forestry mulching grinds invasive plants — stems, root crowns, and all — into fine mulch in a single pass. The Cat HM418 mulching head processes bush honeysuckle, multiflora rose, autumn olive, and Bradford pear up to 8 inches in diameter without leaving stumps or debris. Everything is ground on-site.

The mulch layer left behind serves a critical purpose: it suppresses the seed bank. Invasive species leave thousands of seeds in the soil that can germinate for years after the parent plants are removed. A 2–3 inch mulch layer blocks light from reaching those seeds, reducing the next wave of germination significantly.

For severe infestations where the seed bank is extensive, we recommend a follow-up spot treatment 6–12 months after mulching. The mulching does the heavy lifting — removing 90%+ of the biomass in a day — and targeted herbicide on the regrowth handles what comes back from the root fragments and seed bank. This combination approach is the most effective invasive control strategy per dollar spent.
