A tale of two disturbances: surprises in land management

To keep pace with our growing acreage, ACRES has invested more time and resources in managing, restoring and enhancing land.

In late winter and early spring, we put our new forestry mulcher to work shredding acres of non-native invasive autumn olive. The forestry mulcher, a barrel-like roller attachment for a skid steer, crunches up the offending brush with its heavy tooth-like bumps, leaving a layer of chunky mulch behind.

What will grow in its place? This summer, our team followed up to see how the land responded.

Wabash County

In Wabash County, on our 96-acre protected land near our Kokiwanee preserve, ACRES mulched a dense 5-acre patch of autumn olive, flagging trees to keep them safe from the path of destruction. Beneath the thicket of the invasive shrub, the land was almost entirely bare. The autumn olive had out-competed other plant life and taken over the area.

This brown patch of land, beneath a hand-cut autumn olive brush shows the problem with invasive plant: nothing grows beneath it.

After crunching the invasive brush, the place looked like a wasteland, covered in two-three inches of mulch.

The land donor grew concerned, reaching out to inquire: was it supposed to look this bad? It wasn’t pretty, but this devastation was a critical part of the land’s healing process.

To our delight, this place is recuperating beyond all expectations.

“It’s miraculous,” says Matt Dunno, ACRES land management specialist. “It’s so cool how this land recovered, with so much native plant life coming back.”

The team reported native grasses and flowers filling in, more than a foot high in early summer. Here, native seeds in the soil waiting for the right conditions to germinate, burst forth, reclaiming the land.

Steuben County

In January, Trine University students enrolled in a conservation course began caring for the Beechwood Nature Preserve. In addition to class time, students worked the land, covering more than 14 acres on foot, cutting smaller patches of Autumn Olive brush by hand.

Conservatively, ACRES estimates the students contributed at least 120 hours of labor—a $3,000 value.

The ACRES team matched their investment, mulching an eight-acre thicket of autumn olive.

On returning to Beechwood in the growing season, ACRES found this land covered in garlic mustard, another non-native invasive plant, with a few hopeful native trees pushing through. The team fought the garlic mustard, then seeded with a local genotype native seed mix, thanks to funding from NiSource that also covered other expenses associated with the Trine University partnership.

At Beechwood, on the Wabash County land, in the Cedar Creek Corridor and beyond, ACRES summer land management interns, funded by the Olive B. Cole foundation, sprayed smaller non-native invasive plants.

End results?

ACRES protects land forever, so there’s no end in sight.

Land will continue to change – and with community support, we’ll be ready to support it as needed. We prefer a light touch, but we’re seeing value in our new capacity to intervene more robustly as needed.

On these lands, the ACRES team and our supporters are participating in the initial stages of a process that will take as long as it takes. We’ll keep you posted.

My favorite part of this article is after pulverizing the invasive bush, the area resembled a wasteland, with two to three inches of mulch covering it. Someone recently told me about this and it is different from what I understand. Thanks for helping me understand forestry mulching. https://www.agritract.com.au/ground-maintenance
