How 2 Goats Are Helping to Protect Indiana Dunes National Park

CHICAGO — Scattered throughout the fiery autumn
foliage at Indiana Dunes National Park are green patches of Asiatic
bittersweet, its yellow-orange fruit soon to split open with red
berries, lending a holiday look to the woods.

But this invasive plant is better suited to “Little Shop of Horrors” than any Christmas story.

Its snaking vines can climb at a rapid pace,
enveloping and choking trees, and killing off plants below — a grim
threat in one of the country’s most biodiverse national parks where
native species thrive.

Chemical sprays and controlled burns have been
deployed against invasive plants at the park for years. Now America’s
newest national park is turning to the unique talents of Thelma and
Louise, goat half sisters who were tasked this past summer with eating
as much as they could in an overrun section where tangles of the woody
bittersweet are as big as a fist.

Thelma and Louise worked out so well they could be back at the dunes next year, maybe with some reinforcements.

“They were good company,” said Geof Benson, executive
director of the Dunes Learning Center, which cared for the animals over
the summer. “I think what we need is more goats.”

Thelma and Louise are part of a growing industry as
people turn away from chemical options, according to Midwesterners in
the goat rental business. Goats have helped out major electric companies
by grazing under power lines, cleared beachfront camps along Lake
Michigan and cleaned up backyard gardens. A few years ago, Amazon began
renting out goats.

“More people are discovering that it’s just a lot
easier to let animals do the work,” said Green Goats owner Kim Hunter,
who jokes she’s a “goat goddess” and has lent her Wisconsin herd to
organizations like the Naperville Park District. “Sometimes, just to be
funny, when I pass someone on their mower I yell, ‘Get a goat!’ Life is
too short to spend it doing the work that a goat will do.”

Thelma is a Nubian goat and the more mild-mannered of
the pair. She earned the nickname Jar Jar Binks because of her floppy
ears and mocha color. Louise is white and smaller, part-Saanen. They
were raised by hobby farmer Kyle Wilson, a steel company employee who’s
happy to volunteer his animals for educational projects at the park.

The goats were chosen for their friendliness, he
said. Thelma and Louise are about a year old, like to be petted and have
a sweet spot for Duke, a horse on the Chellberg Farm near the spot
where they spent their three summer months.

On a sunny October afternoon, Thelma left the
chickens, horses and turkeys at the farm and returned to the restoration
site for a tour of her work. Louise, who stayed behind, jumped up on
her hind legs to peer out over the gate. A bleat. Another bleat. But
Thelma walked away.

Jim Whitenack, volunteer program manager of the park,
talked about the project as he walked the path to the goats’ summer
home. Using the goats was a test to see if they could be contained by an
electric fence, if they would eat problematic plants and — the main
point — if they could get visitors to talk about stopping invasives.

One day while exploring, the goats ended up in an
old, empty swimming pool built by U.S. Steel. Thelma and Louise were
hidden from view and caused a momentary panic they had escaped. And
there were some complaints from staff who worked near the enclosure who
said they heard a lot of bleating through the open windows.

But the project was a success: The goats stayed
inside the fence, ate a lot and offered a cute visual to kids learning
about invasive species.

“A big part of it is just talking about the resources
in the park, the biodiversity, all this we have to protect,” Whitenack
said. “And teaching (kids) to be good land stewards.”

A school group was set to visit the next day, and
Whitenack said he would probably bring out a goat. “Whether it’s a
salamander or a toad or a goat or a chicken, yes, people like animals,”
said Benson, of the Dunes Learning Center. “They love the goats.”

The work site is past the Bailly Homestead, on land where U.S. Steel employees once sent their kids to camp.

Camp Good Fellow operated from the early 1940s to the
late ‘70s and offered kids a chance to learn about the environment and
participate in outdoor recreation, Whitenack said. In 1959, the Tribune
reported 1,000 children used the camp that summer for “everything from
dissecting snakes to shooting on a firing range.”

The park then purchased the land but didn’t do much
with it until the 1990s, eventually establishing the Dunes Learning
Center. “It used to be all manicured grass,” Whitenack said. “Then a lot
of invasives came in, and it went horribly bad.”

Whitenack shared some photos from the ’50s showing an
aerial view of the camp with pristinely mowed lawns around courts and
bunkhouses. Then he showed another shot from a few years ago with a slew
of dead ash trees.

“It’s a blanket of bittersweet out there right now,”
Whitenack said. “It probably still looks a little rough for you guys,
but if you just saw it two years ago, it was so bad. So we’re so excited
we got it to this point.”

The fenced-in area where the goats worked covers
about a quarter-acre that’s overrun with bittersweet as well as other
invasives: multiflora rose, bush honeysuckle and garlic mustard. Outside
of the enclosure is a sign: “Goats at Work.”

“If you can imagine having five, 10 goats in here,
they would clear this pretty quick,” Whitenack said, showing off stems
inside the fence, evidence of the goats’ work.

As Thelma returned to her summer home, she stuck her head through an opening and chomped some leaves.

“Want to go back to work?” Whitenack asked.

The park has long focused on curbing invasive
species, using everything from saws and tractors to chemicals and fire.
Because of limited resources, park managers concentrate on rare habitats
and frequently visited areas.

“It’s a tough battle, but we’re making pretty good
headway on it,” said Dan Plath, chief of resource management for the
park. Still, he added, “We’re probably only treating 20% of the park if
we’re lucky.”

Some of the invasives have been in the park for
decades, but others have surged in recent years, he said. Typically,
invasives are non-native plants that run rampant and disrupt the balance
of an ecosystem.

As invasives take over, often arriving from boots,
equipment or birds, one of the first casualties are rare plants. Loss of
habitats for a host of species follows. Invasives can also harm humans
and animals, worsen water quality and be costly.

“They don’t play well with others,” Plath said.

The park is currently fighting against invasives like
phragmites, hybrid cattail, buckthorn, Japanese knotweed and even
wetland species like purple loosestrife.

Asiatic bittersweet, found throughout the park, is a
particularly bad one, Plath said. Some people add it to decorations that
end up outside, and then birds and other animals eat the bright seeds,
depositing them far and wide. Once bittersweet is established, it moves
fast, growing in a year or two from a seed to sprouting plant, and then
soon creating its own seeds, leading to exponential growth.

“They’re kind of pretty, but once you realize what it does, then it’s not so good,” Plath said.

But goats don’t mind eating it. When invasives pass through goats’ digestive systems, the cycle ends.

Plath said the goats are mostly a good reminder to
get people to do their part, raising awareness and encouraging them to
“start planting natives instead of things that are going to invade the
dunes.”

Midwesterners say the goat rental industry is growing as environmental concerns rise.

Kim Hunter of Green Goats estimates a single goat can
clear about 300 square feet of an invasive like buckthorn in a day
without chemicals or clippings. It can be expensive to maintain the
herds and natural restoration takes time, but goats can be a cheaper
solution for larger acreage. And each time goats return, it’s a more
effective clearing process.

“Goats don’t fall down hills, goats don’t have
workman’s comp,” said Hunter, who has lent her goats to a contractor
that had to mitigate invasives while building an electric generating
station. “Goats don’t get poison ivy. They eat poison ivy.”

Dustin Ellinger, an affiliate of Goats on the Go who
is based out of south central Illinois, said goats also “draw a heck of a
crowd.”

“When I unload these, there’s usually 20 people
watching. The people love it, the kids love it. It’s a lot more
enjoyable to watch a goat eat brush than watching a bulldozer plow it
over with a blade.”

Gina Fickle, co-owner of the Michigan-based Munchers
on Hooves and a goat renter of about four years, said she’s watched
goats bring neighborhoods together. “We’ve had people that have
contacted us saying, ‘We’re glad the goats were here. We’ve got new
friends.’”

Fickle said she once put 10 goats together for a job. But they weren’t working, and she didn’t know why.

“Well, we had one goat named Ornery,” Fickle said.
Ornery was a “queen goat” who would shove the other goats in a corner
when she was finished eating. “So they’re like people — if you get the
wrong personalities together, they don’t work well.”

For now, Thelma and Louise remain a team.

Benson, of the Dunes Learning Center, said it would
be fun to have more goats, especially with all the invasive species.
And, he joked, “I wouldn’t even mind trying cows.”
