As kids, many of us come to see
snakes as frightening, evil creatures.
In some places, that ingrained fear
has taken a toll on the snake population.
Karen Kelly met up with some folks
who are trying to improve one snake’s
image – before it disappears:

(sound of truck, bumping on a road)

George Sheffield drives his truck along the dirt path that leads to his family’s
vacation cottage. He keeps an eye out for long, black snakes.

“It might be a good day to see a snake. It was cold last night so they’ll be
looking for sun today to heat back up.”

Sheffield’s land is one of the few places where black rat snakes still thrive in
Ontario. They’re a threatened species here, partly because people have moved
into their habitat.

But also, because they’re often six feet long, so people get scared and kill them.
The black rat snake is the longest snake in Canada. It’s not poisonous, but it’s a
constrictor that eats small animals.

(sound of walking towards cottage)

Once we’re at Sheffield ‘s camp, he checks out one of the snakes’ favorite spots
– the roof of his cottage.

“The one time, there 3 or 4 out on the roof, with portions of others, with their
heads or tails sticking out of soffits. So they do inhabit the cottage. I wish they
didn’t, but until I fix it, I can’t blame them.”

Sheffield is one of a growing number of landowners who are trying to protect
the black rat snake. They’re putting up nesting boxes in fields and wooded
areas to give the snakes a warm and safe place to spend the winter.

But the biggest challenge is just convincing people not to kill them.

Kiesewalter: “Do you want to hold the snake?”

Children: “He’s pretty heavy.” “He feels kind of like rubber.”

Tobi Kiesewalter is a biologist at Murphy’s Point Provincial Park in
southeastern Ontario. It’s used by as many as 500 black rat snakes – as well as
a lot of campers, swimmers, and boaters.

It’s a perfect chance to teach people about the snake. So every day, Kiesewalter
takes a rat snake out of a cage in the visitor’s centre and tries to persuade people
to leave them alone.

“I hear about it all the time, people coming and telling us about how their dad
had killed snakes before. Kids will tell you anything. And, as with many
reptiles, the loss of even one mature adult can cause a dip in population because
we know they’re only reproducing every two years.”

There’s a lot of effort to help this snake. Culverts are dug under highways to
give them a safe route back and forth. There are road signs that say, “Please
brake for snakes.” There’s even an adopt-a-snake program.

But the fact is, the black rat snake isn’t in danger in other parts of North
America. So why save it here?

For George Sheffield, the answer is simple.

“I grew up with them here, I think it would be a shame if man’s activities
caused the end of another species in another area. We’ve already done way too
much to degrade the environment and the number of species, so anything
anybody can do is good.”

A Battle Over the Treatment of Livestock

Recently, six states have changed their laws to require
better conditions for farm animals. But there’s a battle

Recently, six states have changed their laws to require
better conditions for farm animals. But there’s a battle
brewing in one state that’s putting a new spin on the debate.
Julie Grant reports:

The Humane Society of the United States says it’s shameful
the way animals are treated on many American farms. Paul
Shapiro says veal calves, pregnant pigs, and egg-laying
hens are all kept in cages so small – it’s cruel.

“Hundreds of millions of egg-laying hens in the nation are
confined in tiny battery cages that are so restrictive the birds
are unable even to spread their wings.”

Shapiro says some farms house millions of hens, all
squished into tiny cages, and none of them get the chance to
nest, or act in any way like natural chickens. The Humane
Society has spent millions of dollars pushing for change in
California and other states.

But when the Humane Society hit Ohio with its campaign,
the state Farm Bureau Federation pushed back.

Keith Stimpert is spokesman for the Ohio Farm Bureau. He
says there’s a reason cages are a certain size for hens,
calves, and pigs: the animals’ safety.

“You can expand space, but you’re going to increase
aspects of fighting or cannibalistic behavior, or the chance
for that sow to fall down while she’s pregnant.”

Stimpert says the Humane Society doesn’t understand
livestock.

So instead of negotiating with the Humane Society, the Ohio
Farm Bureau is proposing something new: a state board to
oversee the care of livestock.

“I think we, in this case, can get to a better resolution on
animal care by organizing this board.”

The board would include family farmers, veterinarians, a
food safety expert, and a member of a local chapter of the
Humane Society, among others.

Voters will probably be asked in November to decide
whether to change the state constitution to create this board.

But the Humane Society’s Paul Shapiro says the board will
be stacked by the Farm Bureau. He calls it a power grab by
big agriculture.

“Keep in mind that these are people who have opposed,
tooth and nail, any form of agricultural regulation for years,
and now, all of a sudden, in just a few weeks, they’ve gotten
religion and feel grave urgency to enshrine in the state’ s
constitution their own favored system of oversight.”

Shapiro says this board will only protect the status quo. And
that’s not good for the animals.

Egg producer Mark Whipple runs a small farm in Clinton,
Ohio. He’s got about 1,500 hens. We caught up with him
delivering eggs at a local health food store.

He says his hens are free range.

“There ain’t no cages, really. They go in the box, lay their
egg, and go out and run around with the rest of ‘em, go eat,
drink, I don’t know, just be free.”

Whipple says he was never inclined to cage the hens.

You might expect him to side with the Humane Society on
this debate. But he doesn’t trust them to make decisions for
farmers.

“I don’t know that they really know where their food comes
from – other than they go to the grocery store or they go to
the refrigerator. Unfortunately, that’s a lot the mentality of
the world right now, so far removed from the farm at all,
knowing about livestock.”

Whipple says there are good producers and bad producers
out there – just like any business. He would rather see a
board like the one proposed by the farm bureau than a
mandate on cage sizes from a Washington DC-based
lobbying group.

But the Humane Society says the board proposed by the
Farm Bureau won’t make things better. If it’s approved by
voters this November, the Society plans to place its own
initiative on animal treatment on the ballot next year.

Meanwhile, other farm states are considering the Ohio Farm
Bureau’s approach and might soon have their own advisory
boards on how to treat animals.

Interview: Book Blames Coast Guard for Invaders

  • Ships sometimes bring unwanted travelers with them (Photo by Lester Graham)

Invasive species hitchike on foreign cargo ships and end up in US waterways.
Lester Graham talked with the author of a new book about why the government has done so little to stop these aquatic invaders that are damaging the environment:

Lester Graham: “Maybe you’ve heard about Zebra Mussels. The thumbnail-sized mussels have invaded freshwater lakes, rivers, clogged water intake pipes, and damaged the environment across a good portion of the US – and they’re still spreading. The Zebra Mussel is just one of dozens and dozens of invasive species brought into the US by foreign cargo ships entering the Great Lakes though the St. Lawrence Seaway, which connects the Atlantic Ocean to the Great Lakes. What happens is ships in Europe or Africa or Asia take on ballast water, sucking up millions of gallons of water from a foreign port. Aquatic life is sucked up with it. Then, as the ships take on cargo in the Great Lakes, the ballast water is discharged, and with it things like Zebra Mussels and other foreign pests. Many of those species have spread from the Great Lakes into the Mississippi River system, and then transported by recreational boating in every direction from there. Jeff Alexander has written a book that chronicles not only those invasions, but the utter failure of the government to do anything effective to stop these introductions. Jeff, you make the argument that these invasive species, biological pollution if you will, amount to a more serious environmental disaster than the Exxon-Valdez oil spill in Alaska. How’s that?”

Jeff Alexander: “Well the Valdez, there’s no discounting the severity of the Valdez oil spill. But oil spills, over time, can be cleaned up to a certain extent, and the ecosystem can recover. In the Great Lakes, ocean freighters have brought in 57 species, they’ve caused billions of dollars in damage, and they’ve transformed the entire ecosystem.”

Graham: “There are eight states that border the Great Lakes, and members of Congress are aware of this problem, why haven’t they taken action to ensure this problem is dealt with once and for all?”

Alexander: “The shipping lobby has been very effective at keeping regulations at bay, the Coast Guard, which is the lead agency in the US, has just totally dropped the ball on this issue. They’re the ones who’re supposed to be the guardians of the Great Lakes when it comes to ships, and the Coast Guard is very close to the shipping industry. They have social events together every year. A lot of people blame the shipping industry for this problem, but I tend not to. They certainly have fought the regulations but, in the end, the reason that we have regulatory agencies is to protect public health and the environment. And our regulatory agencies haven’t done the job, and our politicians haven’t done the job – no one seems to have the backbone to stand up to the shipping industry and deal with this problem.”

Graham: “Are the foreign ships that bring in this cargo and take away grain or the other things from the Midwest so economically valuable that it is worth this economic and environmental cost?”

Alexander: “There is some debate on that, but the best economic study estimated if we kept these ocean freighters out of the Great Lakes, made them offload their cargo in Montreal and put it on trains and trucks, it would cost us an extra $55 million a year to move that cargo. That’s compared to the estimate of $200 million a year that foreign species are costing us in terms of economic and environmental damage. It’s not a stretch to make the case that the environmental and economic costs have far exceeded the economic benefits.”

Graham: “Jeff Alexander’s new book is ‘Pandora’s Locks: The Opening of the Great Lakes St. Lawrence Seaway’. Thanks, Jeff.”

Alexander: “Thank you.”

Hotlines for Wild Animal Rescue

  • Possums pretty much just want to be left alone – and they let you know by opening their mouths full of teeth. It’s called an alligator gape. (Photo by Patti Roman)

Let’s say you find a baby chipmunk that fell

out of a tree… or worse, you hit an animal with your car.

Who do you call? Rebecca Williams has the story of people

who feel it’s their duty to nurse these animals back to health…

and get them back to the wild:

Let’s say you find a baby chipmunk that fell out of a tree… or worse, you hit an animal with your car. Who do you call? Rebecca Williams has the story of people who feel it’s their duty to nurse these animals back to health… and get them back to the wild:


(sound of phone ringing)


“Thank you for calling the Friends of Wildlife hotline for squirrels, chipmunks and other small rodents. If you have rescued a small animal please keep it warm and quiet…” (beep)

There are hotlines like these set up all over the country. There are bunny hotlines, woodchuck hotlines… you name it and there’s a volunteer hotline for it.

The woman who answers the Possum Hotline is Patti Roman. She volunteers in Michigan. She has a basement full of baby possums.

“Mom has 13 babies so if you get a weekend where two or three moms are hit I’ll get a lot of babies in a few days.”

She says possums get hit by cars a lot. They love to eat roadkill, and they’ll just sit there in the middle of the road, staring at your headlights.

Possums are marsupials like kangaroos. Except they don’t hop out of the way. They keep their babies in their pouches. When a mom gets hit, a lot of times the babies will survive. Someone will find the babies and call the Possum Hotline.

Patti Roman says she’s had up to a hundred baby possums in her basement at one time.

She puts gloves on before she pulls a possum out of its terrarium. I don’t know if you know possums, but they look like a huge hairy rat on its worst day. But this baby possum is kinda cute. He’s giving us a sharp-toothed little grin. It’s a I’ll-rip-your-hand off kind of grin.

“He’s doing the alligator gape right now. But he’s not biting me, but he is trying to scare me.”

That mouth full of sharp teeth is your first clue that possums just want to be left alone. If your dog chases after one, the possum might play dead. Then it’ll get up and waddle off when you’re not looking.

Patti Roman takes care of the possums until they’re a few months old. Then she takes them into the woods and lets them go. She says wildlife is always better off in the wild. But she says she does get criticized for interfering with nature.

“A possum who gets hit by a car is not supposed to die. It has nothing to do with natural selection. And if we can help I think we should.”

But some scientists debate that. Jim Harding is a wildlife specialist at Michigan State University.

“I think the majority of rehabilitation efforts is often just based on a human need to care for things. It isn’t really related to conservation unless you’re dealing with a very rare species.”

Harding says rehabbing some types of common animals can actually make things worse. For example – he says there are so many raccoons that they can wipe out a lot of birds because they eat their eggs.

But Patti Roman says she really feels like she’s doing the right thing. She spent 18 years at the Humane Society rescuing dogs and cats. But she never knew for sure those animals would be placed in good homes.

“When you call to check on the animal a year later – it’s been given away or run away or accidentally been killed. It was breaking my heart. And after awhile I thought, you know, I enjoy doing the wild animals because when they’re ready to go I’m not dependent on people anymore. It feeds my soul. It really does. I do this and I feel very, very good every morning that I can save a life.”

She says when she lets the possums go they don’t look back. They just take off into the woods. And even if that little possum ends up getting eaten by a fox, Roman says that’s okay, because at least that’s natural.

Sea Squirts Sucking Up Species

  • A colony of tunicates in Guam (Photo by David Burdick, courtesy of NOAA)

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:

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.
