Lots of people worry about the extinction of animal species. But plant conservationists
say plants are even more threatened than animals. People are starting to go to great
lengths to protect them. There are banks set up to save seeds and large-scale efforts to
educate people about threats to plants. Researchers, park biologists, and others have
teamed up in one state to save a type of wildflower. Julie Grant reports:


Biologist Mike Johnson is trying to walk carefully. He’s balancing a tray of plastic
containers while hiking down damp, sun-dappled cliffs. Each container holds a few starts
of northern monkshood. These wildflowers have only been found in four states.
Johnson is in Gorge Park, one of only three places in Ohio where monkshood have been
found:


“And, in Gorge Metropark they only exist in one area, and that makes them very
vulnerable to both natural and human induced impacts.”


People who walked the Gorge in the 1980s remember seeing thousands of the blue-
hooded wildflowers. But by 2000, there were only 13 of the plants left here. Johnson
says they were being killed by the salt used to melt ice and snow on a recently built
highway. People dug a ditch to divert melted salt that washed off the road. The monkshood have
done a little better since then. There’s now a stand with 190 of them, but
conservationists want to make sure this wildflower survives long term. Today Johnson is
planting new monkshood starts on the opposite side of the River, away from the
highway:


“So the goal is to establish satellite populations throughout the Gorge Metropark, so if
for some reason they were to die out in one area, they wouldn’t die out in the park
altogether.”


You might think that Johnson and other plant people could just collect seeds from the
surviving monkshood in order to grow new plants, but the director of conservation at
the Holden Arboretum says seeds aren’t reliable enough. They often don’t grow into
plants. Brian Parsons says that when the monkshood population started to decline, the
Arboretum started looking for new ways to preserve the plant’s genetic diversity:


“The only true way to capture that is to clone the plants, so we made the recommendation
to investigate cloning because scientific literature indicated that plant potentially had the
capacity to respond to that type of propogation.”


The Cincinnati Zoo plant research program specializes in plant cloning. So it cloned the
monkshood that Mike Johnson and another biologist are planting today.


Down in the gorge, they use a trowel to dig around in the rocky soil. They’re looking for
planting conditions that will give the monkshood the best chance to survive:


“Literally, that, over there is perfect. There’s not full sunlight. The trees above are
filtering out a lot of it. Just a little sunlight is getting down to the bottom and you’ve got
cool, clear springs. And even though we have all the surrounding development, there are
still springs in the gorge that are fairly uncontaminated from urban runoff and pollution.”


Water drips onto the biologists from the overhanging rock formations. They plant a
couple of monkshoods right in the crevices of the rocks. The leaves are reminiscent of a
buttercup. They are in the same family of plants. They’re not in bloom now. In the
spring, the delicate blue flowers remind some people of a religious hood. That’s how the
plant got its name.


Once Johnson puts these small monkshood starts in the soil, it’s hard to distinguish them
from the other ground-cover. That’s not a bad thing. Johnson says it’s best if people don’t
know exactly where to find the rare northern monkshood:


Grant: “You think people would poach them or something?”


Johnson: “Yeah. Yeah. It’s possible. We don’t generally try to advertise their location.
Anytime something’s rare, it’s valuable and somebody might want to take it.”


Plant specialists believe each plant species provides a purpose in nature, and might hold
some promise for pharmaceuticals or some other use. They’re just not sure yet what
people can learn from the northern monkshood. That’s why they want to make sure it
survives.

New National Board Aims to Protect Native Fish

A new, national effort to protect aquatic species and habitats could bring
needed cooperation between state and federal agencies. Individual states
aren’t able to deal with the problems themselves, but say the newly-
formed coalition of partners might help. The GLRC’s Kaomi Goetz
reports:


The goal of the National Fish Habitat Action Plan is to clean up the
nation’s rivers, lakes and coastal areas. It also seeks to protect the more
than 800 different kinds of native fish from extinction. The plan is based
on an earlier successful model focused on the nation’s waterfowl.


Federal agencies, industry, tribal and non-profits groups have signed on.
So have several state Department of Natural Resources. Gary Whelan is
with the Michigan DNR, one of the agencies that’s signed on.


“When you’re trying to deal with things like water quantity in a system, and you
have a 100 dam owners you’re trying to communicate with, a couple
(state) agencies can’t possibly do that, nor do we have the financial
resources so you really need a broad-based coalition of people.”


Whelan says the initiative will mean a lot more money for states to
address water quality problems and fish habitat.


Organizers are creating a national board to coordinate all the efforts.

Extinction is a natural process, but scientists point out that humans have
sped that process up. A new study maps out the places on earth where
species are in the greatest danger of going extinct. The Great Lakes Radio
Consortium’s Rebecca Williams reports:


Conservation biologists are most concerned about endangered animals and
plants that are confined to just one location on earth, such as one
mountaintop, one lake, or one farm.


A new study finds there are close to 800 endangered species worldwide that
are found in single remaining sites.


Taylor Ricketts is the lead author of the study published in the
Proceedings of the National Academy of Sciences. He says historically, most
extinctions have been on islands, but the species at risk now are found more
often on the mainlands.


“And I think that’s because our footprint on the mainlands has just grown,
and our habitat conversion of a lot of these places has intensified so much
that even the not particularly susceptible species are beginning to be
threatened with extinction.”


Ricketts says two thirds of these isolated sites don’t have full legal
protection. He points out it’s hard to protect species that are on land
with competing uses, such as agriculture, timber harvest or houses.

Living Out Aldo Leopold’s Legacy

If you feel you just cannot live without wild things, you have something in
common with a conservationist who’s still influencing conservation practices almost
sixty years after his death. Scholars say the theories of Aldo Leopold continue to help shape wildlife management and land preservation, especially in the Upper Midwest. The Great
Lakes Radio Consortium’s Chuck Quirmbach reports:


Aldo Leopold is probably best known for writing A Sand
County Almanac. That’s a collection of essays about finding harmony
with nature. His ideas about preservation changed while working for the
Forest
Service in the southwestern U.S. Rick Stel of the Aldo Leopold
Foundation
says one day in the early 1900’s Leopold shot a wolf thought to be a threat
to
cattle. The female had pups with her.


“And he says he got there in time to see the
fierce green fire die in her eyes… and it was at this time he realized
we’re going about this in the wrong way… we really need to look at all
creatures and everything as a community.”


Leopold’s epiphany led to writings that won him national attention. he
eventually moved to Madison, Wisconsin – first to work in forest
research and later at the University of Wisconsin. There, he taught the
nation’s
first course in game management.


In 1935, he bought an abandoned farm in the sandy floodplain of the
Wisconsin River. It became the inspiration for many of the essays in A Sand County
Almanac.


(sound of unlocking door)


Most tours of the site start at an old chicken coop that was the only
building left when Leopold bought the place and is the only structure
now. The shack, as Leopold called it, has no electricity or furnace.


(sound of fire)


On chilly days tour guides light a fire in the fireplace and talk about
the ideas Leopold developed while visiting the shack with his family.
The Leopold Foundation’s Buddy Huffaker says Leopold worried about
becoming disconnected from nature.


“His February essay talks about the two spiritual dangers of
not owning a farm. One is to assume food comes from a grocery store, and the second is that heat comes from a furnace.”


Outside the shack Leopold and his family worked to return the land to its
pre-agricultural state. They planted thousands of pine trees. The also undertook
one of
the first prairie restorations. The Leopold family spent a lot of time
discussing how
people were damaging the environment.


(sound of brushing)


About one hundred yards from the shack Buddy Huffaker brushes off
a plaque that’s set in the ground. at this spot, Leopold sawed apart a
lightning-damaged oak tree that he called the good oak. He wrote
about the experience in a famous essay that Huffaker says is really
about natural history.


“As he and his family saw through the growth rings of the oak, he
goes back in time to see how people have disregarded other natural
elements in the landscape – the decimation of turkeys and other
species that we hunted into extinction locally or entirely.”


But turkeys, sandhill cranes and a few others species have come
back–in part because of Leopold’s conservation ethic. Now his
followers are trying to protect more things.


To spread Leopold’s message some groups have started sponsoring
readings of Aldo Leopold’s A Sand County Almanac. At a library in Lake
Geneva
Wisconsin Jim Celano reads from the essay about the good oak.


“Now our saw bites into the 1920’s the Babbittian
decade when everything grew bigger and better in heedlessness and
arrogance – until 1929 when stock markets crumpled. If the oak heard them
fall, its
wood gives no sign.”


Celano is a former commerical real estate developer who now heads
a land conservancy group. He says he’s trying to convey Leopold’s
ideas to other developers.


“That we’re not here to say no to development… but to ask
they be sensitive to what they’re developing. And when you step on
their parcel, after their development is done, that the first thing you
notice is what they’re preserved and protected.”


(sound of woodpecker and traffic)


But even Aldo Leopold’s famous land around the shack is not immune
from modern threats. As a woodpecker hammers overhead, the noise
from a nearby interstate highway intrudes into the scenery. The
Leopold foundation’s Buddy Huffaker says Aldo Leopold knew the future
would bring new threats to the natural world.


“But I think that’s Leopold’s challenge to us. He
understood progress was going to continue. He just wanted us to
contemplate what we wanted that progress to be. And how far it
should go.”


And with sales of A Sand County Almanac bigger now than when it was
published in 1949, it ‘s a future Aldo Leopold might be helping to
shape.

Dire Warnings From Worldwide Frog Study

  • Due to many different catalysts, including climate and habitat change, amphibians are said to be rapidly disappearing. (Photo by Linda Lundberg)

The most comprehensive study of amphibians ever done shows nearly a third of species
are theatened with extinction. The Great Lakes Radio Consortium’s Erin Toner reports:


More than five hundred scientists from more than sixty nations were involved in the
recent Global Amphibian Assessment. The three-year study looked at the status of more
than 5700 known species of frogs, toads, caecilians, and salamaders. It found out that
more than thirty percent of them are near extinction. In the Americas and Australia,
outbreaks of a highly infectious fungal disease have hurt amphibian populations.


But worldwide, the report says the biggest factors for the decline are habitat destruction
and pollution. It also says since amphibians depend on freshwater to survive, the loss
of species shows the Earth’s freshwater supply is in danger. But scientists say the
negative trend could reverse with a swift commitment of resources, such as creating new
protective areas and captive breeding grounds, and better protection of fresh water.

Groups Sue Bush Administration Over Wildlife Rule

Transcript

Environmentalists are suing the Bush administration
for repealing rules that protect wildlife in national
forests. The Great Lakes Radio Consortium’s Lester
Graham reports:


During the Reagan administration, regulations were
put in place that required the Forest Service to
ensure non-timber resources such as water, wildlife
and recreation were given due consideration and that
the wildlife be managed to maintain viable populations.
Tim Preso is a staff attorney for Earthjustice, one of
the groups that filed the lawsuit in federal court.


“Now, through a quiet rule-making, the Bush
administration is proposing to strip that protection
away and make it legal to drive wildlife toward
extinction in the national forests. We don’t think
that’s right and we don’t think that’s what the
majority of Americans support and we’re going to
seek to overturn it in the federal courts.”


Without public notice or public comment, the Bush
administration set aside the rule in favor of a less
restrictive guideline that relies on what’s called
“best available science.” One Forest Service official
says it doesn’t change things that much.


For the Great Lakes Radio Consortium, this is Lester
Graham.

Cost of Taking Eagle Off Endangered Species List

With more than 7600 breeding pairs in the continental United States alone, the American Bald Eagle has made a remarkable comeback. A new proposal to remove the bird from the Endangered Species list is expected soon. But that means removing a powerful safety net that can affect future research, monitoring and habitat protection. The Great Lakes Radio Consortium’s Sally Eisele reports:

With more than 7600 breeding pairs in the continental United States alone, the
American Bald Eagle has made a remarkable comeback. A new proposal to remove the
bird from the Endangered Species list is expected soon. But that means removing a
powerful safety net that can affect future research, monitoring and habitat protection.
The Great Lakes Radio Consortium’s Sally Eisele reports:


In the history of the Endangered Species Act, only a dozen or so of the more than 1200
plants and animals listed as threatened or endangered have actually recovered. The eagle
may be the latest to join that little group.


(Young birder: “I see a big birdie…”)


This is a pretty unlikely spot for an eagle — a manmade wetland by a landfill in a busy
airport flight path on the outskirts of Detroit. But state wildlife biologist Joe Robison
shows this young visitor the bulky nest across the marsh where two adult birds are
teaching their gangly fledglings to fly.


“Something just landed in the tree out there. Oh. That’s the other juvenile. This is the
first time I’ve seen them flying this year. They look like they’re flying good though.”


These birds are among more than 400 pairs in Michigan monitored by state and federal
wildlife officials. The eagles are banded, the nests are watched and when a bird dies it
ends up in the freezer of wildlife pathologist Tom Cooley.


(sound of Cooley opening the freezer)


“Lots and lots of ’em. You can see that one was a road kill along I-75…”


Right now, Cooley’s freezer is brim full of dead birds stacked like frozen Thanksgiving
turkeys in plastic bags. Road kill has become the leading cause of death among eagles
he examines, but Cooley says they still investigate suspicious looking deaths for the
heavy metals and pesticides—like DDT—which once caused the eagles’ demise.


“Birds that kind of send up a red flag to us are adult birds that are in poor condition and
you don’t see a reason why they could be in poor condition. Those are the ones that we
especially look at for pesticide analysis because there are still the organochlorines out
there. The DDTs are still picked up by eagles or still contained in eagles. Those
pesticides can cause real problems for them and actually kill them.”


Cooley sends tissue samples to another state lab for analysis. But the testing is
expensive. And with the eagle on the way to recovery, it’s not as urgent. Right now, he
says all the samples he sends are being archived—shelved basically. That means the
testing won’t be done until the money is available.


“I never like archiving anything if I can help it. You’re probably not missing anything
but that kind of data is always nice to have if you can get it right away and look at it right
away.”


The question is, if it’s hard to get funding for monitoring and testing now—while the bird
is still on the Endangered Species List—what happens when it’s taken off the list? The
reality, say state and federal wildlife experts, is that budget priorities change as a species
recovers. Ray Rustem heads Michigan’s non-game wildlife program.


“There’s not enough money for every species. So you try to take a species to a level
where you feel comfortable with and you take money and apply it to another species to
try to recover.”


The federal Endangered Species Act requires the Fish and Wildlife Service to monitor
what it terms a delisted species for five years. After that, responsibility largely shifts to
the states. That concerns groups like the National Wildlife Federation. Attorney John
Kostyak questions whether states can really afford to protect fragile species and their
habitat over the long term.


“That’s going to be an issue with any delisting. A tough question that we’re going to
always be asking is: all right assume you go forward with delisting—how are you going
to be sure the species doesn’t turn right around and go back toward extinction again?”


With some species, that means habitat management. With others, like the recovering
gray wolf, it means public education—teaching people not to kill them. With the eagle, it
means ensuring that the birds are not threatened by the pesticides, heavy metals and
newer chemicals that contaminate the fish the eagles eat. Because of the bird’s
importance as an indicator species, Fish and Wildlife biologists are hopeful banding and
testing programs will continue after delisting. But it will likely mean finding new ways
to pay for them.

Saving the American Eel

  • Eel fisherman John Rorabeck near his home and fishery on Point Traverse, near Kingston on northeastern Lake Ontario. He says these waters were once practically boiling with eels. One night, he caught 3 tons of eels. Today he's lucky to catch one eel. (Photo by David Sommerstein)

For centuries, the American eel dominated the waters of parts of the Great Lakes. Only fifty years ago, the snake-like fish accounted for half of the biomass of Lake Ontario. Today, it has all but disappeared. Researchers and fishermen see the decline as a shrill warning about changes in climate and the environment. And they say now is the time to do something about it.

For centuries, the American eel dominated the waters of parts of the Great Lakes. Only
fifty years ago, the snake-like fish accounted for half of the biomass of Lake Ontario.
Today, it has all but disappeared. Researchers and fishermen see the decline as a shrill
warning about changes in climate and the environment. And they say now is the time to
do something about it. The Great Lakes Radio Consortium’s David Sommerstein reports:


Before you say, who cares about a slimy critter like an eel, hear me out. Eels are
amazing.


They spawn in the Sargasso Sea – the Bermuda Triangle. But no one’s ever caught them
in the act.


“There is a mystery that we haven’t solved. We have never seen them spawn.”


After they’re born, they’re like tiny glassy leaves. They float thousands of miles north
and west on ocean currents. Then they wiggle up rivers and streams from Florida to
Quebec.


“The eel is a fish that we should be looking at very closely.”


They live up to 20 years in freshwater before they start the long journey to the Sargasso
to spawn.


The problem is their offspring are not coming back.


“A very important native species of the Great Lakes, that we’re at serious risk of losing.”


As you can hear, a lot of people are worried about the eel, and not just in the Great Lakes.
European eel young are down 99% from the 1970’s. The Japanese eel is down 80%. In
Lake Ontario, the fish is all but gone. And the people who rely on it feel like they’re
disappearing too.


(sound up of waves)


Just ask fisherman John Rorabeck. He grew up here by the lighthouse on Point Traverse,
a peninsula that juts out into northeastern Lake Ontario.


Rorabeck’s been fishing these waters for more than thirty years. Eels were his prime
catch. He points past the lighthouse.


“I remember when I started fishing there were nights on that south shore, the most fish
that was in there would be eels at certain times and there was literally tons of them on
that south shore. Now you could go back and you’ll find nothing.”


He stopped fishing eels three years ago because it just wasn’t worth it.


“That eel is telling man we better smarten up because this is happening all over the
world.”


Now Rorabeck dedicates his fishing time to science. He catches specimens for leading
eel expert John Casselman, who examines them in his lab.


“It is truly a crisis. A crisis of concern.”


Casselman’s a scientist at the Glenora Fisheries Station, run by the Ontario Ministry of
Natural Resources. In 1980, at a point on the St. Lawrence River in mid-summer, he
counted more than 25,000 eels a day. Last year, there were scarcely 20 a day.


Casselman ticks off a host of possible causes – overfishing, dammed-up rivers, erosion,
pollution, invasive species, and perhaps most troubling, a climactic change of cooling
ocean currents.


“There is an interrelationship between what’s going on in the ocean and the recruitment of
eels.”


And he says we’re mostly to blame. The problem is, Casselman and other researchers
don’t know exactly how all the factors relate or which is worse. And they say there’s no
time to find out. Last summer eel experts from 18 countries made an unusual statement.
In what’s now called the Quebec Declaration of Concern, they urged more action, not
more science.


“I’m a research scientist and of course, I love data. At this stage, you don’t want me.
Don’t ask me to explain what’s going on here because by the time I get it figured out, it
may be too late.”


The Great Lakes Fishery Commission has issued an emergency declaration of its own. It
represents commercial fishermen and anglers in the region. Spokesman Mark Gaden
says it’s calling on the U.S. and Canada to do everything they can to reduce eel deaths in
the Great Lakes.


“We’re committing ourselves, our resources to working to make the recovery of the
species a reality.”


Last month, the province of Ontario halted commercial eel fishing for the foreseeable
future.


(sound up at beach)


Fisherman John Rorabeck supports that plan. He stares out across the waters he’s trawled
for decades. He says he’s behind anything to bring the eel back to Lake Ontario for
future generations.


“And hopefully we can. But…I don’t expect to see it in my time. When I… (crying)
…when I think of all the times that we’ve had out in the lake and my forefathers and see
what’s happening here, it breaks you down.”


Rorabeck says when he thinks of the eel nearing extinction, he feels like he and his way
of life are becoming extinct too.

Volunteers Tally Migrating Cranes

The colder weather and shorter days are keeping most of us inside. But
for a group of volunteers it’s the perfect time to head outdoors. They’re
putting on their gloves and setting up their spotting scopes to go out and
watch one of their favorite birds get ready for the long trip south. The
Great Lakes Radio Consortium’s Mark Brush reports these birds gather by
the thousands before migrating:


(Sound of cranes)


It’s a dreary and damp evening next to this marsh in rural southeast
Michigan.
The dampness has that edge of cold to it that’s hard to escape.
And while most people are heading to their warm homes for the day –
things here at the Haehnle Bird Sanctuary are just getting started as
volunteers count cranes:


(sound of cranes flying overhead and volunteers)


“I got a whole line of coming in over the flats out there – oh, man – It’s
startin’… how many?”


“Thirty-four.” (sound of clicks)


With the help of a clicker, three volunteers from the Audubon Society
count the birds.
Fortunately for them, the birds they’re counting are… really big.
The Greater Sandhill Crane is one of the biggest birds in the region.
They glide into the sanctuary by the thousands with their gangly legs
dangling behind them.
They’re counting the birds for the U.S. Fish and Wildlife Service.
This is part of a wider effort in the region to get an overall count of the
crane population.
They have one night to count – and tonight’s the night.


Gary Siegrist is one of the volunteers. He says the birds come into this
wetland after a day feasting in the farm fields:


“They’ve been out feeding all day… and they stage… this is one of two
places in southern Michigan where they stage. And when they get to a
point where they have enough fuel in their bodies enough fat built up, and
their food supplies are gone, and maybe the mud lake is frozen over, then
they’ll find a favorable wind and head south.”


The gathering is an instinct for these birds. During the summer months
they spread out across the region in pairs. But when it’s time to migrate
they get together in big flocks before they head to Florida. And when they
gather in large numbers – it can get noisy.


Gary Siegrist says the bird’s call is one of the things that draws him here
to count the birds year after year:


“People don’t realize that it’s the oldest living bird species. They’ve got a
relative that goes back 35 or 65 million years – it’s the time of the
dinosaurs…the bird is fantastic and if you can hear the call, you
can hear it in the background, it kind of sends shivers down your back. It
reminds you of a different time.”


(sound of cranes flying by)


The volunteers also spend their time chatting with people who visit the
Sanctuary. And even on a cold night like tonight – people have come out
to see the birds.


Phil DeLang drove with his wife and grandson two and a half hours just to
watch the gathering… and they do it every year:


“I think all of nature is precious, I me an it’s really precious when you
think of things becoming extinct, like the passenger pigeon, what a
tragedy, it never should have happened. I’m just glad there’s places like
this. People have taken the effort to give these birds a home.”


(sound of counting)


The birds continue to arrive by the hundreds as the sun begins to set. As
darkness falls – the volunteers tally up their final number:


“Twenty nine seventy five. Tweny-nine seventy five? Yeah. O.k.”


The count for the evening is over. And by their calculation nearly 3000
birds are settling down for the night.


(3 seconds of sound at night)


The volunteers head home to double check their math – and send in their
final numbers.


(bring up morning birds)


The next morning at the sanctuary the birds are waking up and heading
into the farm fields.


We caught up with Ron Hoffman here. He’s the guy who coordinates the
official crane count for this region. And between all the volunteers that
counted last night – they spotted 4,600 cranes.
Ron has been studying these birds since the 1960’s when they were just
coming off the threatened species list. And he’s seen the bird’s population
grow steadily over the years.


But Ron Hoffman and the other volunteers see a pattern developing in this
area – a pattern that could threaten the number of cranes that use this
sanctuary. The Haehnle sanctuary is surrounded by spreading housing
developments. They fear these developments would use up farmland,
which is important to the birds:


“I’m sure we’ll always have cranes, but at the same time if this area within
ten fifteen miles of hear is so built up that there’s not the food reserves
here for the cranes to feed, then the number of cranes using this would be
diminished.”


But no matter how many cranes are out here, you can bet Ron Hoffman
and the other volunteers will be counting them year after year.
They care about these birds.


While we were talking, he interrupted to watch a young bird fly by:


“This guy is really lost – look he’s coming back over.” (sound of little
bird) Did you see him craning his neck and looking? He’s trying to find
his parents…”


Hoffman says his biggest hope for the Greater Sandhill Crane is that the
population will remain stable, so that he and others can continue to
experience what he calls one of the wildlife spectaculars in this region.

Every winter, millions of monarch butterflies migrate from backyards in
North America to nestle in trees in Mexico. The weather conditions in the
mountains there are perfect for the insect. But scientists say climate change could
spell disaster for the species. The Great Lakes Radio Consortium’s Todd Melby has
this report:


The fir trees in central Mexico are ideal conditions for the monarch
butterflies of North America to spend the winter. The habitat there is cool
and dry.


“They are looking for a refrigerator.”


That’s Karen Oberhauser, a researcher at the University of Minnesota. She
Says the orange-and-black-speckled butterflies spend up to five months there
Before coming north again.


The new study was published in the Proceedings of the National Academy of
Sciences. It shows that the biggest threat to the monarch’s Mexican habitat
may be an increase in rainfall. She says that would cause the monarchs to freeze
