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.

Rats Scurrying to the Suburbs

  • Life in the suburbs is idyllic to some people... (Photo by Bon Searle)

Unusually heavy rains this summer are partly to blame

Unusually heavy rains this summer are partly to blame for rats pouring out of the sewers
in droves all over the country. And the nasty vermin are relocating to some of the most
pristine neighborhoods. The Great Lakes Radio Consortium’s Joyce Kryszak explains what
caused the rat invasion and what’s being done to evict them:


Piercing blue autumn skies and billowing white clouds drift across the chimneys of this modest,
but perfectly manicured suburb. There aren’t even many leaves crunching under foot. Town workers
have already come and vacuumed them all away. But there’s a nasty little secret scurrying under
the porches and behind the garden sheds in this Western New York town. County Sanitation Chief
Peter Tripi takes us for a peek.


“Can you see the teeth marks here? That’s actually rat gnaw marks. And there’s the garbage bag.
And that’s what we found when we went to this property.”


Now, you might be thinking that we trudged through derelict grass and scattered debris to find
these rat clues. Nope. This is a gorgeous, manicured yard – with not a blade of grass out of
place. But Tripi says rats aren’t choosy.


“You would never think by looking side to side that there would be a rat problem in this yard.
Doesn’t matter what neighborhood you live in, or how much money you’ve got. There’s no difference.
They just like your food.”


And you’d be surprised where rats can find food. A garbage can left even briefly uncovered, a
neglected bird feeder, uhhh… dog feces… and even a compost pile.


“Absolutely. This is a rat condo. It’s a grass-clipping compost pile that basically housed rats
to go a hundred yard radius all the way around to the different houses.”


Tripi says rats had to get creative with their housing. A summer of extremely heavy rains drove
the out of the sewers and into some previously rat-free neighborhoods. And with the West Nile
virus killing off millions of birds, the rats have less competition for the food they’re finding
above ground. The consequence is a virtual rat infestation all the way from New York and Illinois
to Virginia, Michigan and L.A. In Kenmore, there have been four thousand rat complaints – nearly
double last year.


(Sound of garbage truck)


Of course, none of this is news to the garbage collectors. They see the problem up close and
personal. Twenty-year veteran Louie Tadaro says this past summer is the worst he’s ever seen.


“Across the street there’s an alleyway and there had to be like ten of them in there, And we
started chasing them with garbage cans trying to kill them, but we couldn’t. By the time we
got there they just split.”


The problem is, they don’t split for long. Vector Control Chief Tripi says now that the rats
have relocated from the sewers to upscale accommodations, they kind of like it.


“And what that means is that they want to live with us. They want to be near our garbage and
our bird feeders. The problem with that is that rats carry diseases.”


We all know about stuff like typhus and the bubonic plague. But there are emerging diseases,
such as a pet-killer called Leptospiroris. It’s killing dogs all across the country. Tripi
says they need to get rid of the rats before the disease starts spreading to humans. So, his
team is taking the rats on, one yard at a time.


Tripi and his Vector control team set rat traps, they fill bait boxes with poison, and – when
they have to – they issue citations to residents who don’t heed the town’s new “rat control rules.” Covered garbage cans only. Clear away all brush. Clean up scattered bird seed and dog feces. Slowly, the rules seem to be working.


(sound of Tripi looking into rat trap)


Still Tripi says it’s mostly educational warfare. And he says now – heading into winter – is the
best time to nip the problem. If the rats get cozy, not only will they stay, they will multiply.
Fully nourished, one adult rat can breed up to sixty baby rats a year.


“The adult rat can live on a little bit of food, but he can’t procreate unless he has a lot of
food source. And they can’t live through the winter unless they’re warm and fattened up.”


So now is the time to – quite literally – put a lid on it. Keep those garbage cans covered, unless
you want some uninvited furry guests this winter, and many, many more come spring.

Setting Traps for Emerald Ash Borer

The emerald ash borer has been destroying ash trees in Michigan, Ohio,
Illinois, Maryland, and Ontario – and the bug is spreading. Now,
agricultural officials in Michigan are developing an early warning
system. By detecting the insects early, they hope to slow or even
prevent its spread. The Great Lakes Radio Consortium’s Tracy Samilton
reports:


Forestry agents will be designating a number of so-called trap trees in
every township in Michigan. The ash trees will act as sentinels. A
strip of bark will be removed from the trees, which stresses them and
makes them attractive to insects. A sticky substance called tanglefoot
will then be applied to the trees to catch the borers. Kara Bouchay is
with the Michigan Department of Natural Resources.


“Part of the struggle with having a borer that you can’t see most of
time because it’s underneath the bark, is when it’s in a low level
population, it basically flies under the radar. So the trap tree is a
way to bring it to a single location to detect it.”


If borers are found on a tree, all ash trees within a half-mile will be
destroyed to contain its spread. Bouchay says if the early detection
system proves itself, it will likely be implemented in other states as
well.
