There are places where some wildlife
that once thrived, are now gone. In
Wisconsin, the Pine Marten has been
wiped out. The shy animal looks a bit
like a ferret. Pine Martens are members
of the weasel family. Barbara Jean Johnson
went out with researchers to see how
they’re bringing Pine Martens back to
northern Wisconsin:

You probably have never seen a pine marten. But I’m spending the day with two guys who spend weeks at a time looking for them. They work for the Wisconsin DNR. We’re actually in a county in northern Minnesota. We’re crammed into a Ford Ranger pickup, driving on the back roads to check trap lines. We’re looking for Pine Martens in Minnesota that will be released in northern Wisconsin.

Pine Marten’s were wiped out or extirpated in Wisconsin over the last hundred years. The Marten’s were in trouble once European settlers moved in. A combination of forest fires reduced animal habitat. Already too many of the animals were trapped for their pelts. But then the Great Depression hit.

“Trapping was a valuable commodity. Fur prices were high and many farmers and farm boys feed their families off their trap lines, and given that there’re weren’t many regulations, or limited regulations, and the high value, I don’t doubt that they over harvested, as well.”

That’s Jeff Wilson. He’s on the frontlines of this varmint capture mission. He and his partner Dan Haskell are seeking to right some of the past wrongs. Dan and Jeff are fun guys. They love the wilderness and they like to chat. The only downside to our little expedition is the smell that permeates the cab. I didn’t say anything, but it smells like skunk.

“Now you do admit, you do smell a little skunk essence in here, do you not? We do our best you know. we shower everyday, but we have been getting a few looks at the grocery stores and the places we’ve been shopping in your Grand Marais community. We hope we haven’t offended anybody.”

These guys us a skunk scent to lure Pine Martens to live-traps. They love the scent. And, they’re not the only ones. Apparently this skunk compound is used in the famous French perfume Chanel No. 5. Some of their colleagues have actually used the perfume as a lure when trapping lynx in Canada.

“However, Chanel No. 5 is like $90 an ounce. (laughs) So we don’t use it.”

Dan and Jeff don’t want just any kind of marten. They already have all the males they need. They want females. As we make our way from trap to trap we catch male after male – seriously, five males – and no females.

“My wife says it’s because they are smarter, but I think it’s because they have a much smaller home range – maybe a half a mile to a mile. In contrast, males cover around two to three miles. You’re just going to get more males. If you set a trap line and spread it out, there’s going to be about two or three times more possibility of a male capture than a female capture.”

(sound of animal screaming)

Catch six, and we’re all hoping it’s a girl. But they have to check to make sure. Marten’s may be small, but they’re certainly not known for being cuddly.

Jeff coaxes the marten head-first into the corner of a laundry bag. He puts a tight hold on its head while Dan peels back the bag to check the genitalia. Once they know they’ve captured a female, they sedate her and run through a series of basic tests to collect data. They also give each animal they take home a name.

“This one is obviously going to be called ‘Barbara’ after you, our colleague. (laughter) You’re a breath of fresh air – literally. (laughter)”

Yeah, they’re a little lonely out in the field. Not a lot of people spend much time with them – smelling a little like skunk and all. And they’re away from home for extended periods of time. But, all in all, they both enjoy what they do and find real meaning in it.

“We can restore what we’ve mismanaged in the past and it’s inspirational for me to see there’s no doubt there’s a niche for this animal there. This animal is a really important part of biological diversity and I’m really happy I can participate in that.” For The Environment Report, I’m Barbara Jean Johnson.

Dental Offices Adding to Mercury Problem

Dental offices are producing higher levels than
expected of a toxic form of mercury. Rebecca Williams
reports on the findings of a new study:

When dentists remove fillings, most of the mercury in the fillings is
trapped in a filter in the spit drains. But some of it does get through.

Mercury in its simplest form is not as toxic as what’s called methyl
mercury. That forms when mercury is exposed to certain bacteria. Methyl
mercury is very toxic even in small amounts.

Researchers at the University of Illinois say they found much higher levels
of methyl mercury in wastewater from dental offices than they expected. In
fact – they say they were the highest levels of methyl mercury ever reported
in an environmental water sample. And that toxic mercury is eventually
released into the environment.

The findings were published online in the journal Environmental Science and
Technology.

To put this all in perspective – the authors say the amount of mercury
coming from dental offices is really, really tiny compared to mercury coming
from coal-fired power plants.

Delisting the Gray Wolf

Some populations of gray wolves could be taken off the endangered species list. The U.S. Fish and Wildlife Service is expected to issue proposed new rules for gray wolves in the upper Great Lakes region in the next week or so. We have more from the Great Lakes Radio Consortium’s Tracy Samilton:

Some populations of grey wolves could be taken off the endangered
species list. The U.S. Fish and Wildlife Service is expected to issue
proposed new rules for gray wolves in the upper Great Lakes region in
the next week or so. We have more from the Great Lakes Radio
Consortium’s Tracy Samilton:


The growth of the grey wolf population in the Great Lakes area is good
or bad, depending on who you talk to. Wolves help control deer herds,
but they also prey on livestock.


Adrien Wydeven is with the Wisconsin Department of Natural
Resources. He says in extreme cases, states might want to let farmers
who’ve had problems shoot wolves they catch in the act of killing
livestock.


“And we could consider the possibility of a public harvest of members of
general public applying for permits to trap or hunt wolves in limited
areas.”


There will be a 90-day public comment period before the delisting of
Great Lakes wolves is adopted. It will apply mainly to wolves in
Michigan, Wisconsin, and Minnesota. Each state will also have to adopt
its own wolf management plan.

Pheromone to Help Control Lamprey?

Researchers say they’ve discovered a migration pheromone

Transcript

Researchers say they’ve discovered a migration pheromone in sea lamprey. It’s a natural attractant that could boost efforts to control the invasive parasite. The Great Lakes Radio Consortium’s Stephanie Hemphill reports:


Each lamprey can kill forty pounds of fish in its lifetime. Managers use a pesticide to keep the lamprey numbers down, but it’s expensive, and sometimes it kills other fish.


University of Minnesota biologist Peter Sorensen says he’s isolated a chemical signal put out by lamprey larvae. The larvae live in streams, and the signal apparently tells adult lamprey that the stream is a good place to lay eggs.


“We’ve got a cue that’s very powerful, very safe, we don’t need very much of it, and it can control the distribution of the lamprey in a way that other things can’t.”


Sorensen says the pheromone can be used to corral lamprey into areas where they can be trapped or treated with pesticide. The pheromone is being tested in a river in Michigan.

Controlling Feral Cat Colonies

Cats are the nation’s most popular household pets. But despite this, millions of cats are abandoned each year. These free-roaming cats grow up without much human contact. They live in cat colonies near apartment buildings, strip malls, or anyplace else where food scraps get tossed into dumpsters or trash cans. And they have an impact on the environment as they compete with other wildlife for food and shelter. The Great Lakes Radio Consortium’s Rick Pluta has this report:

Cats are the nation’s most popular household pets. But despite this, millions of cats are abandoned each year. These free-roaming cats grow up without much human contact. They live in cat colonies near apartment buildings, strip malls, or anyplace else where food scraps get tossed into dumpsters or trash cans. And they have an impact on the environment as they compete with other wildlife for food and shelter. The Great Lakes Radio Consortium’s Rick Pluta has this report:


It’s late at night and Donna Dunn and a couple of friends are sitting in a parked car in a suburban Detroit cemetery.


They’re smoking, eating fast food, and waiting for cats.


“There’s the pregnant female, right there under the truck…”


They’re hoping the cats wander into one of the dozens of live traps they’ve set up. The prize catch is a pregnant female.


“What’d you get? Is it a girl? Yeah, it’s a girl… a pregnant female. Yes! Alright!….”


Donna Dunn is a veterinary technician, who learned about feral cats through her job. She hooked up with a sprawling network of thousands of feline lovers who take care of feral cats living in cat colonies.


Dunn figures there are about 75 wild or abandoned cats wandering the grounds of this cemetery. Some of the cats live in tunnels burrowed in the dirt, or in buildings on the cemetery grounds. Wild cats can also live in vacant buildings or abandoned vehicles. And, Dunn figures, there would soon be a lot more cats if something wasn’t done about it.


“One female will have a minimum of two litters a summer, average litter is five kittens per litter. So you’re looking at 10 kittens average per female in here. The first nine females we took out of here, eight were pregnant. That would’ve produced 40 kittens.”


(Sound of trap)


The trapped cats will spend the night in cages stacked side-by-side in a volunteer’s garage. They’ll go the vet’s in the morning, before they are returned to their feral cat colony. Donna Dunn says the neutered cats are more content, and less likely to fight with other cats and wild animals.


She says “trap, neuter, and release” is a humane alternative to turning strays over to a shelter, where most of the cats would be killed.


But “trap, neuter, and release” is also controversial idea. Critics say it doesn’t really address the problem of feral cats roaming the streets. They say it’s simply not possible to sterilize millions of these cats.


Eileen Liska is with the Michigan Humane Society. She says wild cats have a profound effect on the environment. They can upset the ecological balance of a field or a neighborhood by killing off birds and other wildlife. They can also carry feline leukemia and other diseases. Liska says euthanizing un-adoptable felines is the most compassionate approach.


“Cats living out in the streets equals suffering. I mean, they are suffering. They don’t have proper food sources. They’re exposed to the weather and they’ve got the danger of being attacked, injured or killed by other wildlife, especially when they’re fighting for the same ecological niches. The cats absolutely are in competition with possums, skunks, and raccoons, and raccoons can grow quite large and be quite aggressive and we know that they kill cats that come, that get in their way.”


But Liska also says the growing number of wild cats shows the current approach isn’t working. She wants to raise more money to fund new animal control programs. But she’s not finding a lot of support for a tax to do that among Michigan’s politicians.


Michigan, like most states, requires dogs to be on a leash or fenced in when they’re outside. Farmers demanded the laws at the beginning of the twentieth Century because wild canines were attacking livestock.


There’s no similar cry yet to do something about feral cats, and no one seems to think that licensing cats would begin to get at the problem. Wisconsin proposed allowing hunters to shoot strays. That idea was tabled after animal rights groups protested.


“Right there. See it? Right out here. That’s a little one. Judy, is there food in there? Should I check it?”


Donna Dunn and her friends would like to see every state to adopt trap-neuter-and-release for dealing with stray cats. Until then, she says, her cohorts will try and deal with the problem one cat colony at a time.

Searching for Salamanders at Old Nuke Site

Government workers are slogging around in man-made wetlands looking for salamanders. Back in the 1950’s, the United States government selected a plot of land to be the home of its newest uranium processing plant. Since the end of the Cold War, the now-closed nuclear processing plant has been undergoing the long and arduous task of returning to its natural wetland state. The Great Lakes Radio Consortium’s Tana Weingartner reports on the search for salamanders at the site, and why their presence is so important:


It’s a cold, windy day in late March as specialists from the Ohio Environmental Protection Agency head out to check their traps at the Fernald Nuclear Plant. The 1050-acre facility sits in a rural area just 18 miles north of Cincinnati. Although the EPA is in charge of cleaning up the uranium contamination here, today they’re on a different mission. Today they’re hunting salamanders.


“Salamanders basically are a sign of an established wetland usually, and in this case would show that we put a wetland in a location where salamanders need additional breeding habitat.”


In other words, Schneider says the presence of salamanders indicates the first level of success for these manmade wetlands. The wetland project is one of several ways the EPA is ensuring Fernald is properly restored to its natural state.


“Well, we’re looking forward to the day when we get the site cleaned up, and it can be like a land lab, and people can bring kids out here and do environmental education on the importance of wetlands, and it’s going to make a great contrast with what used to be here and the environmental contamination with the environmental benefit the facility is providing down the road.”


Today, the site is 70 percent certified clean, and officials expect to finish the cleanup by June 2006. Creating healthy wetlands full of insects, amphibians and salamanders is one of the first steps to success.


“So the method here is to set ten traps equidistant, hopefully, around the perimeter of the wetland. And they’re passive traps, whereby animals that are moving over the course of the 24 hours or so that the traps have been in, will bump into the traps and it’s a funnel that directs them into the center part of the trap, and they’re held in there until we release them.”


(splashing sound)


Schneider and his team laugh and joke as they pull the traps up by brightly colored ribbons. Train horns and construction noises mix with bird calls – one a reminder of what has been, the other a sign of what’s to come.


“That’s probably a one-year-old bullfrog there and then these big guys are dragonfly larvae and these other guys are back swimmers. Mayfly larvae and dragonfly larvae are both good indicators of high water quality.”


The third pond, or vernal pool, turns up 46 tadpoles and a tiny peeper frog, but no salamanders.


(truck door slams)


So it’s back in the truck and on down the dirt road to where several more wetland pools sit just across from the on-site waste dump. That dump will be Fernald’s lasting reminder of its former use. These pools are younger and less established, but they do offer hope. Last year, adult salamanders were found in the one closest to a clump of trees.


Each spring, as the snow melts away and temperatures rise, salamanders venture out in the first 50-degree rain to begin their search for a mate. Schneider had hoped warm temperatures in late February and early March prompted “The Big Night,” as it’s known.


“So, no salamanders today?”


“No salamanders today. I think we learned a little bit about the difference between wetlands that are three years old. We saw a lot more diversity in the macroinvertebrates, the insect population, than we have down here.”


Perhaps the salamanders haven’t come yet, or maybe they have already come and gone, leaving behind the still un-hatched eggs. Either way, the team will check back again in April and a third time in late May or June.


“And we have high hopes, high hopes, high apple pie in the sky hopes. That’s the kind.”


(sound of laughter)

States Seek Permission to Kill Problem Wolves

  • In the Midwest, grey wolf populations are on the rise, leading some to believe that wildlife management practices are needed. (Photo courtesy of the National Park Service)

Transcript

Some Midwest states are re-gaining permission to euthanize grey
wolves that are killing domesticated animals. The Great Lakes Radio
Consortium’s Chuck Quirmbach reports:


A federal court ruling in January halted agencies in Wisconsin and Michigan
from trapping and killing problem wolves. The U.S. Fish and Wildlife
Service has just given Wisconsin a new permit to euthanize up to 34
wolves this year, and a permit application from Michigan is being
reviewed.


Fish and Wildlife official Ron Refsnider says two years of data show
the killing of problem wolves is not harming the grey wolf
population in the upper Midwest states.


“So we don’t have to guess, we don’t have to speculate. We can see
flat out that what they’re asking for shouldn’t be a problem.”


A small number of grey wolves have traveled into other Midwest
states. But officials there still can only trap and relocate problem wolves.

Capturing Waste-Heat in Smokestacks

Engineers say they have a new system that will extract more energy out of coal-fired power plants. And, they say, it has the added benefit of reducing pollution. The Great Lakes Radio Consortium’s Mark Brush reports:

Transcript

Engineers say they have a new system that will extract more energy out
of coal-fired power plants. And, they say, it has the added benefit of
reducing pollution. The Great Lakes Radio Consortium’s Mark Brush
reports:


Coal-fired power plants convert only one-third of the fuel’s energy
potential into electricity. The rest of that energy is heat that’s
lost out the smokestack. Engineers say they’ve now found a way to
capture that heat, transferring its energy into electricity.


Dan Stinger is president of Wow Energies. He says reducing heat in
smokestacks has an added benefit:


“Not only are we able to generate power from waste heat without
consuming fuel, which is an immediate reduction in pollution. But
we’re also able to knock the temperature out of an exhaust stack or
flue gas, and by doing that we condense out a lot of the pollutants
that normally would be exhausted into the environment up a huge exhaust
stack.”


Stinger says a cooler smokestack means fewer pollutants, such as
mercury and chemicals that cause acid rain and ozone, will be sent up
into the atmosphere. Instead, much of that pollution will be condensed
out and trapped. Stinger says the company plans to install its first
small-scale system by the middle of next year.

Trapping Laws Come Under Fire

Trapping is still a popular past time in the northern half of the
country. Mostly trappers are looking for beavers, raccoons and

Trapping is still a popular pastime in the northern half of the country. Mostly, trappers are

looking for beavers, raccoons, and muskrats. But every year, a small number fo household pets are

caught as well. As the Great Lakes Radio Consortium’s Karen Kelly reports, one pet owner is

fighting to change that.


Valentine was Meg Massaro’s best friend. She was a black and brown boxer. And, at one time, a

mangy stray. Massaro found her on the side of the road and nursed her back to health. The two

became inseperable. Then, on a cold January morning, they went for a run on a local bike path.


“So I let her off the leash. She bounded happily in front of me for about thirty seconds. The next

thing I know I heard her screaming and I jumped in after her and she was sailing through the air

with a bucket over her head. I took the bucket off her head and there was a trap and I said to my

husband, ‘What is it?’ She kept looking at me, pleadingly her eyes were just getting bigger and

bigger. She couldn’t breathe. And animal control with the help of police were finally able to get

it off. It was about an hour and a half that she was in the trap. Of course, by that time, she was

long gone. It was gruesome, very grisly.”


The trap was about fifty feet from this bike path just outside of Albany, New York. Massaro

remembers thinking this had to be illegal. It’s an area with playgrounds and picnic benches. So,

she called New York’s Department of Environmental Conservation, and found out the trap was legally

set.


“They were really like, ‘Well what do you want us to do, lady?’ And I said, ‘I want you to go out

and see if there are any more traps and if there are, I want you to remove them.’ And the guy

said, ‘We wouldn’t be able to do that.’ So I just said, ‘Thank you very much,’ and hung up the and

I thought, ‘This is war.'”


Massaro started calling newspapers. She circulated a petition with thousands of names. And she

began lobbying – full time – to get traps out of residential areas.


“I can’t imagine that anyone wants traps near their home, near where their kids play, near where

their dogs are walking; it doesn’t make any sense to allow that.”


Albany County legislator Paulette Barletti talked to Massaro over the phone after the incident.

But she wasn’t sure it was an issue she wanted to adopt. Then, she saw photographs the police took

after Valentine’s death.


“I was actually horrified. And the first thing that came to my mind was, good grief, this could be

a child.”


Barletti introduced legislation to ban trapping on state or private land. That’s because New York,

like most states, regulates trapping on the state level. Traps can be set on most state land and

on private land with permission of the landowner.


Gordon Batcheller runs New York’s Department of Environmental Conservation’s trapping program. He

says trappers often serve as their eyes and ears in the field.


“Trapping is actually very hard, it’s hard work and it takes a lot of skills. Studies have shown

that trappers, of all outdoor users, have the highest level of all wildlife biology. They’re

extremely knowledgeable about animals. They can tell us what’s going on out there and we really

value what they tell us because they’re knowledgeable and they see things.”


Batcheller says the majority of trappers are extremely careful about where they set their traps.

And there aren’t too many pets being caught. but Batcheller says it’s clear that in those cases,

the trapper made a mistake.


“In the incidents that we’ve evaluated, the traps simply should not have been set where they were

set. Even though it was legal, poor judgement was used in those instances and experienced trappers

that look at these cases, they shake their heads and say why did they do that.”


Now, thanks in part to Meg Massaro’s campaign, Batcheller is trying to find a compromise. He’s

come up with new recommendations. They’d require trappers to move traps off the ground and onto

stands and trees where dogs can’t reach them. And, he’s proposing tougher restrictions near roads

and bike paths. Batcheller hopes the recommendations will be in place by next fall. But Meg

Massaro says it’s not enough. She’s lobbying for local control so counties can make their own

decisions about trapping. And she wants traps banned from recreational areas. But mostly, she

wants to make sure that this never happens to someone’s dog again.


“When I drover her home that first time, tears were running down my cheks that day because I

couldn’t believe how abused this dog had been. And i promised, I said it out loud to her, no one

will ever hurt you again. And I lied. I didn’t mean to, but i lied and i can’t live with that. I

have to do something to compensate for that. She deserved better, and other people and their pets

deserve better.”
