Slimy, hungry invaders are moving through
the waters off the Northwest coast of the US.
They’re called invasive tunicates –
or sea squirts. And they’re the same invasive
species that devastated shellfish farms on Canada’s
east coast. If invasive tunicates aren’t controlled,
you could see a lot of seafood options disappear
from markets and menus. Ann Dornfeld has the story:

It’s a peaceful spring morning at this suburban marina. But beneath the water’s surface, a hunt is
underway.

(water sounds)

Professional divers – like Jesse Schultz with the Washington Department of Fish and Wildlife – are
combing the docks for invasive tunicates. They don’t have to look far.

“That’s one of the tunicates right there – that’s the guy right there.”

Schultz surfaces holding a jelly-like tube. Sea squirts compete with everything from clams to tube
worms for the plankton they all eat. The sea squirts usually win, because they don’t have native
predators. Three species came here from Asia, probably on boat hulls. Today, divers are cleaning
the hulls of local boats to keep the sea squirts from spreading.

Allen Pleus manages invasive species for the state.

“The whole intent right now is a containment action. We want to prevent any of these boats
from leaving this harbor with the tunicates attached to their bottom, going to another
harbor, and infesting that harbor or marina.”

When invasive tunicates get to a new harbor, they quickly become the dominant species. In the
warm part of the year, they spawn every 24 hours. And along with hogging the food supply, one
species of sea squirts forms a slimy mat that smothers mussels and other shellfish.

Pleus says if tunicates get out of hand, they could make a big impact on the seafood industry.

“It can definitely affect especially shellfishing in this area. Puget Sound, Western Washington is one of
the largest producers of shellfish in the nation. It could also affect other populations of
food fish, including salmon, by taking out a lot of the nutrients that juvenile salmon feed
on.”

Nova Scotia learned that lesson the hard way. Pleus says in Eastern Canada, entire shellfish
farms were recently wiped out by invasive tunicates.

“So the rap sheet is clear. They can grow to exponential sizes, quantities and smother
aquaculture facilities. They can’t even lift up their lines it’s so heavy with these critters on
it.”

To prevent the same thing from happening here, the state workers have to move quickly – and
they have to be thorough.

“Here’s another bag, Justin!” (splashing sound)

Back in the water, diving biologist Jesse Schultz has his hands full with a boat that has apparently
been docked for seven years. Its tabs show that’s the last time it was registered.

“This guy’s getting a free boat cleaning, sort of!”

The state is trying to scrape clean every infested boat in Puget Sound before the summer boating
season. But Schultz says because the docks are still covered with invasive tunicates, they’ll grow
back on this boat if the owner doesn’t keep it clean.

“That’s the biggest thing these guys can do to keep these things from spreading is have
their boats maintained.”

The state is still figuring out the best way to clean the docks. So far biologists have cleaned only
one entirely. When they were done, they’d removed ten tons of critters.

Unfortunately, Allen Pleus says only some of those were tunicates. In order to get rid of the
invasive sea squirts, they have to employ a sort of scorched earth policy.

“That is one of the hardest parts of this is that we have to basically take everything out.”

That means the good with the bad. We sift through a bucket of the creatures scraped from the
dock. Along with plenty of invasive tunicates, there are brightly colored sea cucumbers, scallops,
mussels, rock oysters, feather duster worms and chitons – exactly the kinds of animals the state
is trying to protect. They have to destroy the habitat in order to try to save it.

that will kill invasive zebra and quagga mussels.
The mussels got into the US in the ballast of

the country. Rebecca Williams reports:

So, let’s say you have a nasty pest, an invasive species. Then someone says, we can get rid of that
pest and it looks like there’s no environmental downside.

“It kinda sounds like snake oil. But it’s true.”

That’s Dan Molloy with the New York State Museum lab. He’s come up with a
way to kill zebra and quagga mussels.

Molloy says a strain of common bacteria is toxic to zebra and quagga
mussels. And, even if the bacteria are dead, they can still kill the
mussels.

“You know maybe horror stories of people applying biocontrol agents. And it
had effects they didn’t anticipate. We’re applying dead cells. And they’re
just as effective live or dead.”

It’s great news for power plants, because the mussels clog up intake
pipes.

But it’s not clear if the bacteria can kill mussels in open water.

Big Ships Required to Flush

  • A ship discharging its ballast water (Photo courtesy of the US Geological Survey)

Ships should be bringing in fewer unwanted pests into the Great
Lakes. Both Canada and the U.S. are now requiring ships to flush out their
ballast water tanks before entering the lakes. Tracy Samilton reports:

Ships need to take on ballast water to keep them stable. When they pump in
water from freshwater foreign ports, they also suck up pests.

Since 2006,
Canada has required ships to flush their tanks with salty ocean water
before entering the Great Lakes. The U.S. adopted the requirement at the
start of this year.

Collister Johnson is with the U.S. side of the St.
Lawrence Seaway, which connects the Atlantic Ocean to the Great
Lakes. He says the rule will eliminate almost 99% of freshwater
pests in ballast tanks.

“If they’re exposed to salt water, especially full strength sea water, they
are effectively killed.”

Samilton: “Why didn’t we do this before?”

Johnson: (laughs) “I don’t know.”

It won’t completely eliminate the problem because some aquatic pests can
still survive in the sediment in the bottom of ballast tanks.

  • Where is it?! Oh! There it is - up in the corner - eeek! (Photo by Tom Wojnowski)

More and more people are moving into areas that are natural habitats for animals. And a lot of people are finding that the animals don’t want to move out of the neighborhood. Kyle Norris reports that this can make for some interesting interactions:

More and more people are moving into areas that are natural habitats for animals. And a lot of people are finding that the animals don’t want to move out of the neighborhood. Kyle Norris reports that this can make for some interesting interactions:


Get this: woodpeckers want to live inside Tom Wojnowski’s house.


“There’s a hole. And when you’re in house here’s what you hear, you hear this: (knocks) and you know you’re being attacked!”


Wojnowski is not so keen on sharing his house with the woodpeckers. He managed to scare that one away, but then another woodpecker made a pretty good-sized hole on the other side of the house.


Wojnowski put up one of those menacing plastic owls, you know, to scare the woodpecker away – and he thinks it’s working. He’ll probably even buy another plastic owl. You know, with those cute eyes, all wide.


Wojnowski lives in a suburb, but it’s sort of out in the country. There are dirt roads, and lots of trees. And lots of wildlife in the area.


Wojnowski started having problems with animals pretty much the day they moved into the house. Actually, he can list off his problems to the ABCs.


“Well let’s start with A. Ants haven’t been a big problem. There’s been a few but none in the house and they’re out there so I leave them alone. B. You have bees and bats.”

Ok, this could go on for a while… so I’m going to jump in here.

Bats were living in the attic. Carpenter bees chewed holes in the siding. So, for “D” you’ve got deer. The deer ate pretty much all the landscaped plants. Ok so now, let’s jump to “F.”


There was this fox. It had been living in Wojnowski’s drainage ditch. And it would bury its kill in the lawn—things like dead, smelly skunks. Yeah.

So, one day Wojnowski was getting his mail and the fox came strolling out of woods. And they locked eyes.


Wojnowski noticed the fox was small and red… and beautiful.

But he was tired of dealing with it.


“So I took this rock and I put it in front of the drainage ditch hole. And he watched me do that and it was almost like ‘what are you doing to me here?’ So then he went next door and went to their drainage ditch.”

Wojnowski is not the only guy who’s battling it out with the wildlife.


As people keep moving into areas near wildlife, there are problems. I mean at a certain point it starts to feel like…(Boxing announcer: in this corner, with acres of ravaged lawns and gardens to their credit, we have the wildlife. (applause and boos) And in this corner, with a hoe, live traps, and a BB gun, we have the human homeowners…” (applause and boos and the ‘ding’ of the boxing bell)


But experts say it does not actually have to be ‘us’ versus ‘them’.

Jennifer Kleitch is a wildlife technician with the Michigan Department of Natural Resources.


She says people need to realize that they’re part of the problem.


Dog food outside is a free meal for coyotes. People who mow their lawns all the way to the edge of their pond create paradise for geese: short grass near water.


And then there’s this kind of thing which can happen with raccoons:


“If we leave out our garbage and they get into it, we get mad and they’re being a nuisance. But we are in essence responsible for them being there and being drawn to it.”


She says people tend look at it as if animals are the problem. But… the people moved into the animals’ neighborhood.


Stephen Vantassel says we’re conflicted about wildlife. He’s a wildlife damage educator with the University of Nebraska Lincoln Extension office.


“We tend to have the Disney effect with wildlife. We have these rather pastoral images of a person walking through a deep forest and seeing the deer in the distance. And then that attitude can change dramatically when they see that same deer ravaging a plant they paid $500 for to have put in their backyard.”


He says when people start thinking of wildlife as “evil” (As in, “that thing that tore up my flower bed is ‘evil’”) well, that can be bad.


The animals are not the enemy… they’re part of the environment… the same environment that people want to live in.


So… Tom Wojnowski? You know, the ABC guy?


Well, he says his perspective has changed a little over time. He still thinks if animals are destroying his property… yeah, well then they’ve got to go. But he’s starting to realize there are things he can do to discourage wildlife from damaging his property… without waging war.


He’s kind of getting into it actually. He’s started reading up on different animals. He says he likes and respects animals… even the mole tearing up his lawn. He thought it was a whole colony. Turned out… it was just one mole. But one heck of a hard-working mole.

Experts say there are plenty of cheap, simple things you can do just to prevent problems.

Like modify bird feeders to guard against squirrels. Chimney caps discourage uninvited guests from dropping in. And people can fill in the cracks and crevices around their home to stop things like bees and mice from sneaking in.

But the experts say that the best thing you can do is cool your jets. Stop viewing the animal as the problem. And realize that the animal is just trying to do its thing.

As for the wildlife around Tom Wojnowski’s place, well, they’re stalled at the letter W. Which is the first letter in his last name. The animals are still trying to learn to live with him.

Fish Stocking Taxing

  • As fewer Brown Trout from a state stocking program survive in the waters of Thunder Bay in Lake Huron, the fish takes on the allure of a trophy fish, especially since those that do survive can grow very large. Last year, a 28 pound Brown Trout won the tournament. It may be the biggest Brown ever to be caught in the state of Michigan. (Photo by Linda Stephan)

Most cities have their symbols. Imagine San Francisco without
the Golden Gate, New York without the Statue of Liberty, or

community that has linked itself with a fish that is not native to

Most cities have their symbols. Imagine San Francisco without
the Golden Gate, New York without the Statue of Liberty, or
Miami without dolphins. Linda Stephan has the story of a
community that has linked itself with a fish that is not native to
its waters. And stocking that fish is costing taxpayers a lot:


The brown trout arrived in Lake Huron’s Thunder Bay by a
fluke. Back in the 1970s, about a thousand fish – surplus stocks
from inland waters – were simply tossed out into the bay by
biologists, as if the bay were a trash bin.


No one expected them to survive. They thought they’d just be
food for other fish. But the brown trout did survive. They
quickly grew large and feisty. The state started to stock these
waters with young brown trout every year because anglers
liked catching them.


In fact, it was so popular, they named a fishing tournament after
it: the brown trout Festival in Alpena, Michigan. This year, a
crowd of hundreds gathered, despite periodic rain showers, as
festival o-“FISH”-als weighed in a day’s catch… lake trout, walleye:


(Sound of announcer at tournament)


You don’t need a brown trout to win at the brown trout
Festival. And it’s a good thing because these days, most boats
don’t catch even one. That’s because things have changed.


The ecosystems of Lake Huron and the other Great Lakes are
changing rapidly, as foreign invasive species, such as the zebra and
quagga mussels, steal away food at the bottom of the lake’s
food web.


Plus, a migratory bird that’s been showing up in this bay in huge
numbers, cormorants, have been eating the small browns
stocked by state fish nurseries before the fish ever make it into
open waters.


For the past decade, the Brown hasn’t survived all that well in
Lake Huron. So today biologists estimate that, taking into
account all those fish that don’t survive, every time an angler
catches a big Brownie, it now costs taxpayers close to
three hundred dollars.


In other words, each brown trout caught represents about
three hundred dollars spent by the state stocking program.
Even though the brown trout is not native, people here say the
fish belongs in these waters.


Hobbyist Dick Cadarette at the brown trout Festival says the Brown has a special allure for
the angler:


“Well, because they’re the best eating and they’re the hardest to
catch. That’s why we call it the brown trout because anybody
can catch a steelhead – I mean a lake trout – but they can’t
everybody catch a Brown.”


As the large fish becomes more and more elusive, it takes on
the allure of a trophy fish.


Fisheries Biologist Dave Fielder says because of the cost – for
years now – the state has had good reason to quit stocking these
waters with brown trout, but they still haven’t. No one’s
willing to see the namesake of the brown trout Festival
disappear:


“What’s always amazed me is how the natural resources in
Michigan, including the fisheries that we enjoy in the Great
Lakes, is really a part of that local heritage and quality of
life for these local communities and becomes an important part of the local existance and indentity it’s important that we
as scientists don’t lose sight of that.”


But some say the fact that the local community has gotten used
to seeing the brown trout does not mean it belongs in the lake.
Mark Ebener is a Fisheries Biologist for the Chippewa-Ottawa
Resource Authority. It regulates fishing for five Native
American tribes:


“You tell a lie long enough and sooner or later people
believe it and accept it as the truth. You know it’s not that
brown trout belong here. brown trout were introduced
and they continue to be defined as an introduced species
into North America.”


Ebener says since the brown trout does no harm to native fish,
such as the lake trout, his organization doesn’t oppose the
stocking program. But he also says at the current cost, the
brown trout is a clear waste of taxpayer money.


Back in Alpena, Biologist Dave Fielder agrees the state can’t
keep stocking the lake with browns if so few continue to
survive. But, an angler himself, he looks with envy on a
mounted brown that took last year’s top prize in the tournament,
an unbelievable 28.2 pounds:


“Can you imagine landin’ that fish? That must have been
somethin’. Anybody’s who’s caught fish can look at that and imagine the battle they must’ve went through and the excitement they must’ve felt. And those are real feelings and that’s not to be
trivialized.”


That’s evidence to Fielder, and others who fish these waters,
that at least some brown trout have what it takes to complete
for food in the changing ecosystems of Lake Huron.

An oil refinery is expanding in part to meet growing demand for gasoline. The
refinery planned to dump more waste into the Great Lakes. Laura Weber reports
the refinery company is now delaying those plans:


British Petroleum plans to expand its Indiana refinery near Lake Michigan.
State and federal authorities have given BP permission to dump more ammonia
and sludge into the lake.


This is the first time a company has been allowed to dump more pollution into the
Great Lakes since the Clean Water Act was passed in 1977.


But BP is putting its plans on hold after meeting with Congressional leaders.
US Senator Debbie Stabenow says Congress wants to make sure BP will dump the
least amount of waste possible:


“There is a real question in my mind, particularly, when we’re talking about a Great
Lake that’s impacted by a variety of state actions. I think this is an important thing
to look at.”


The expansion plans are delayed until September. A BP spokesman says if there is
additional dumping, it will not harm the Great Lakes ecosystem.

Defending Rights of Nature

Some lawyers believe it’s time to stand for the rights of nature. They want to represent trees. They want to defend the rights of birds and lakes, and all of nature.

Some lawyers believe it’s time to stand for the rights of nature. They
want to represent trees. They want to defend the rights of birds and
lakes, and all of nature. They’re trying to put into practice a theory
called earth jurisprudence. Jennifer Szweda Jordan has the story:


A law seminar on defending the rights of nature is probably not what
you expect, at least not at first. The start of Roman Catholic Sister
Pat Siemen’s law seminar on earth jurisprudence is unorthodox and Zen
like:


“We’re gonna start with our reflection time. And what I’d like you to
do is close your computers.”


Siemen taps a handheld chime in a classroom at Barry Law School in
Orlando, Florida. She has the law students practice slowing down so
they’ll notice what’s going on around them in nature, and they’ll take
the time to really think about arguing for the rights of nature in the
courtroom.


The legal system doesn’t recognize the rights of nature just yet.
Courts interpret the Constitution as protecting needs and rights of
humans. So only humans, or say, groups of humans such as corporations
can sue. The rights of bunnies and trees aren’t entitled to a voice in
courtrooms. Siemen says the emerging field of earth jurisprudence wants
to change that.


Part of the whole thought of earth jurisprudence is that other beings
actually be given their rights -legislatively – to come into court
through the understanding that someone as a guardian or trustee stands
in their right.


Besides teaching this new area of law, Siemen directs the Center for
Earth Jurisprudence. The center’s just wrapped up its first academic
year. Siemen’s early legal work focused on advocating for people who
were poor, minorities, or otherwise marginalized.


Siemen moved in a different direction when she was influenced by
ecotheologian Thomas Berry. Berry says that if the animals and trees
had a voice, they’d vote humans off the planet. Siemen was shocked:


“I had spent my whole life – at least adult life – ministerially trying
to stand in positions of empowerment of others, and furthering the
rights of others and I had never once really thought about what it
meant to be – whether it would be rivers or endangered species – what
it would mean to have to live and exist totally by the decisions of
humans.”


Siemen was also influenced by University of Southern California Law
School professor Christopher D. Stone. Stone wrote an article entitled
“Should Trees Have Standing?” In 1972, Supreme Court Justice William
Douglass agreed that inanimate objects should have rights. But that
view hasn’t gotten very far in American courtrooms.


The idea that ecosystems should have legal rights is problematic in the
view of free-market advocates. Sam Kazman is General Counsel for the
Competitive Enterprise Institute. He calls the theory of earth
jurisprudence gibberish.


“It is impossible to lay out what is in the best interest of an
ecosystem unless you lay out just what you as someone who owns that
ecosystem, or enjoys it, or appreciates it from a distance, what you
hold important.”


In other words, the owner will decide what’s best for the ecosystem.
Some legal experts believe giving nature rights would take nothing less
than a constitutional amendment.


University of Pittsburgh Law Professor Tom Buchele disagrees. He’s an
environmental lawyer who’s used the standing concept – unsuccessfully –
in arguing for a forest. He says that the Supreme Court could, if it
chose, interpret the constitution as allowing nature to have legal
standing:


“There’s certainly nothing in the constitution that says a case or
controversy has to have a person as the entity. It’s just that current
case law doesn’t do that.”


Buchele and Siemen know changes in court decisions are a long way away.
But if teaching about earth jurisprudence can make tomorrow’s corporate
counsels, real estate lawyers, and governmental officials consider the
trees and the water in their work, Siemen feels she’ll have made some
progress.


And getting law students to think about the rights of nature along with
the rights of humans might be the start of the legal revolution Siemen
wants to see.

The Saint Lawrence Seaway is now open to international ship
traffic from the Atlantic Ocean to the Great Lakes. But as
Sarah Hulett reports, the start of this year’s Great Lakes
shipping season is raising questions about a new state law aimed
at protecting the lakes from invasive species:


The state of Michigan is now requiring ocean-going ships that
come into the state’s ports to get ballast water permits, and
agree not to discharge untreated ballast into the lakes.


Ballast water is pumped in and out of a ship to help keep it
level in the water, but ballast water is known to carry small
organisms from foreign waters that can wreak havoc on Great
Lakes’ ecosystems.


So far, only two shipping companies have applied for the
permits. John Jamian heads the Seaway Great Lakes Trade
Association:


“The joke is that the big players that represent over 98% of the
cargo that comes into Michigan ports have not filed for permits.”


Jamian’s organization and others are suing to get the law
overturned. They say it violates the Commerce Clause of the U.S.
Constitution.

water of cargo ships. Once in US waters, some of
the foreign species become invaders, damaging the
ecosystem. The federal government has done little
to stop these invasive species. Rick Pluta reports now some states have decided to take
things into their own hands:


The damage caused by invasive species carried to the US in
ballast water is not only harmful to the environment, but it
hurts the economy. The federal regulations have not stopped the
problem. So, states such as California and Michigan have passed
laws that require foreign ships to treat ballast water like
pollution. They have to clean it up before they can discharge it
into a port. The problem is, almost no ships have a way to treat
the ballast.


In Michigan, the Great Lakes shipping industry is trying to delay
the new Michigan rules. Shipping companies, port owners, and
dock workers say Michigan’s new rules are jeopardizing jobs
without actually stopping the introduction of new species into
the Great Lakes.


The damage caused by invasive species carried to the US in

hurts the economy. The federal regulations have not stopped the
problem. So, states such as California and Michigan have passed
laws that require foreign ships to treat ballast water like

the ballast.


In Michigan, the Great Lakes shipping industry is trying to delay
the new Michigan rules. Shipping companies, port owners, and
dock workers say Michigan’s new rules are jeopardizing jobs
without actually stopping the introduction of new species into
the Great Lakes.


People in the shipping business say the problem is Michigan is
the only state in the Great Lakes region that is requiring ocean-
going freighters to install expensive technology as a condition
of using one of its ports.


John Jamian is the president of the Seaway Great Lakes Trade
Association. He says requiring ocean-going freighters to install
expensive technology before they can dock in Michigan ports won’t
solve the problem. The ships will just go to other Great Lakes
ports.


If a ship goes to Windsor or Toledo that doesn’t have these rules
and regulations, they will discharge their cargo. If there were
any critters on those ships they could still swim or crawl into
Michigan waters, so you still haven’t solved anything.


Jamian represents the owners of ships that travel from the
Atlantic Ocean to the Great Lakes via the Saint Lawrence Seaway.
He says ship owners will very likely avoid Michigan ports, and
choose to unload at ports in other states and Canada:


“The fact of the matter is that they’re not going to put an
expensive piece of equipment just because Michigan calls for it
on their ship when in fact it may not be acceptable anywhere else
in the world and it might just be easier to take that cargo
across the river and unload it where they don’t have these
regulations.”


And for Michigan ports that are near other competing ports,
that’s a concern. Patrick Sutka is the treasurer for Nicholson
Terminal and Dock Company at the Port of Detroit:


“We fear these ships may be going to other ports, such as Windsor
right across the waterway, or other competitors of ours such as
Toledo or Cleveland.”


At the height of the shipping season, there might be three
freighters at a time moored to the docks, offloading steel and
other cargo. A hundred trucks a day will move in and out of the
docking area to get those commodities to factories.


On the dock right now are dozens of stacks of 20-ton slabs of
steel from France and Russia. That Russian steel was most likely
shipped from a port in the Caspian Sea or the Black Sea. The
freighters take on ballast water from those seas for the voyage
to the Great Lakes. That ballast water helps keep the ships low
and steady in the water.


The ships are required to exchange the water in deep ocean mid-
journey. The salt water is supposed to kill the fresh water
organisms. But, some organisms can survive the trip. That’s how
zebra mussels, quagga mussels and the round goby fish made their
way from the Balkans to the Great Lakes.


Those invasive species and others combine to cost the economy an
estimated 5 billion dollars a year. For example, zebra
mussels cost taxpayers and utility customers. It shows up in
your power bill because the utilities have to pay divers to
scrape the crustaceans off pipes carrying cooling water to power
plants.


Shipping companies, port owners, and dock workers’ unions are all
pressuring Michigan to hold off on enforcing its new law. What
they’d really like is for the federal government to step in,
negotiate with Canada, and create a regional set of rules for
combating aquatic invaders:


“…But the federal government has not had the guts or the
gumption to step up to the plate and get this done.”


Patti Birkholz chairs the Michigan Senate Environmental Affairs
Committee. She sponsored the law:


“So we’re going to do it on a state-by-state basis. Our eco-
system within the Great Lakes is what many scientists have termed
‘on the tipping point.’ We cannot deal with any more invasive
species in this system, and we know the majority of the invasive
species come through the ocean-going vessels. They know they’re
the cause. We know they’re the cause. We’ve got to deal with this
situation.”


Michigan’s new law is as much a political statement as anything
else and other states are starting to follow Michigan’s lead.
Birkholz says Wisconsin and New York could pass ballast standards
this year.


In the mean time, Michigan environmental officials say they
intend to enforce the state’s requirements when the Great Lakes
shipping season resumes in the spring. But, so far, no ocean
freighters have applied for a permit to dock at a Michigan Port.

Hedge. It’s a big honeysuckle hedge planted as screening for a missile base
on this land that juts out into Lake Michigan like a crooked finger. When
the Army left in the 70’s, the hedge grew wilder. Migrating birds have been
going nuts over this little area ever since.


“It’s kind of like a bird motel, where on their trips they can stop and rest
and re-energize before they take off again. So it’s just a wonderful
natural oasis within this very dense urban city.”


Jerry Adelmann’s been a fan of green space in the city for decades. He’s
the chair of Mayor Richard Daley’s Nature and Wildlife Committee. Two years
back, Adelmann suggested making a comprehensive inventory of Chicago’s last
remaining scraps of habitat.


“We have some of the rarest ecosystems on the globe – tall grass prairie
remnants, oak savanna, some of our wetland communities are extraordinarily
rare, rarer than the tropical rainforest, and yet they’re here in our forest
preserves and our parks, and in some cases, unprotected.”


The city recently unveiled a new plan to protect these little places in the
city. The Nature and Wildlife Plan highlights one hundred sites, adding up
to almost 5,000 acres. Most of the sites are already part of city
parks or forest lands, but until recently, they didn’t have special
protection.


Kathy Dickhut is with Chicago’s planning department. She says before
Chicago’s recent zoning reform, these sites the city wanted to protect were
zoned as residential or commercial areas. Now they’re zoned as natural
areas.


“Buildings aren’t allowed, parking lots aren’t allowed. This area is not
going to be zoned for any other active use whereas other parts of the parks
we have field houses, zoos, ball fields, but in these areas we’re not going
to have structures.”


Dickhut says even though land’s at a premium in the city, the planning
department hasn’t run into a lot of opposition with the new habitat plan.
She says she just got a lot of blank looks. Local officials were surprised
the city wanted these small pockets of land.


And that actually worked in the city’s favor.
The city’s been able to acquire new lands for habitat that no one else wanted.


“As a rule we don’t like to take the throwaways for parks and habitat. But
in some cases, habitat lands work well where other things won’t work well.
If you’ve got a road and a river and a very skinny piece of land that won’t fit
anything else, that’s good for habitat, because anywhere where land meets water is
good for habitat.”


The city’s also turning an old parking lot back into sand dunes and
elevated train embankments into strips of green space. And though some of this land
isn’t exactly prime real estate, the city does get donations with a little
more charisma.


In Chicago’s industrial southeast side, the U.S. Fish and Wildlife Service
discovered bald eagles nesting in the area for the first time in a century.
The birds were nesting on a 16 acre plot owned by Mittal Steel USA. The
city got the company to donate the land.


Lou Schorsch is a CEO of the steel company:


“Of course, you always would like to keep the option, it’s close to the
facility, if the facility expands, you could put a warehouse there, but we
had no immediate plans for it and I think when the city approached us, given
this unique circumstance of eagles returning to nest there, frankly it was a
relatively easy decision for us.”

Surplus land and a symbolic bird helped the city’s cause in this case. But
the city’s Nature and Wildlife Chair Jerry Adelmann hopes this can be the
beginning of a national trend.


Adelmann says preserving remnants of habitat on industrial lands fits into
Mayor Daley’s larger green vision for the city. It’s a vision Jerry Adelmann thinks doesn’t have to
be at odds with the city’s industrial past.


“I’ve had friends come visit and they think of Chicago as this industrial
center, City of Big Shoulders, gangsters and whatever and then they suddenly
see this physical city that’s so beautiful. Our architecture is world-famous but also our public spaces, our natural areas, our parks I think are
becoming world-famous as well.”


But Adelmann admits it’s early yet. It’s too soon to know how well these
remnants of land will function as habitat and what the city might need to
do to make them better. He says while it’s important to provide green
spaces for birds and bugs, these places are even more important for the people
who live in Chicago. Especially people whose only contact with wildlife
might be in the city.
