The Environmental Protection Agency
has released its first comprehensive
survey of the nation’s lakes. Samara Freemark tells us what
the study turned up:

More than half the nation’s lakes are in good condition. That’s according to a nationwide survey just released by the EPA. But the agency found that 44% of lakes ranked only fair or poor.

The survey identified two major problems facing lakes. First, many of them are surrounded by development. And that can mean dirt and polluted water running off into the lakes.

And second, many lakes contained high levels of nitrogen and phosphorus, which can lead to harmful algae blooms.

Susan Holdsworth is with the EPA. She says those findings were concerning.

“These stressors are both widespread and pose a significant threat to the condition of our nation’s lakes.”

Holdsworth says the EPA will use the data to assess how well government programs are doing at protecting lakes. The results will also help set future EPA priorities.

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.

Climate Change and Wildfires

Twenty years ago this year, the
country watched its oldest national park
go up in flames. Looking back, scientists
believe the 1988 fires of Yellowstone
National Park were the signal fire of
climate change. Researchers have been
working ever since to understand this
relationship between climate and wildfire.
Sadie Babits reports on two scientists
searching for clues to ancient climates,
using trees as their guide:

Jennifer Pierce wears work boots as she plows down a steep slope in a
ponderosa pine forest.

(sound of walking, twigs breaking)

Her blonde hair is tucked up under her Boise State bronco cap, but it keeps
sneaking out. She has to keep brushing it back under. She and her
colleague David Wilkins are professors who work for Boise State
University’s Geosciences Department. They’re in the middle of tall pines in
a forest just outside of Boise, Idaho. Suddenly she’s crashing across the
brambles and heads for this tree.

“Oh that’s a great one! Wow! Sweet!”

She drops to her knees and shows me how this tree has been scarred by
fire.

“You see this little V shaped cat face here at the bottom of the tree that’s
blackened? So during a fire when the bark of the tree gets damaged that
preserves a record of the fire as a scar on the tree.”

Pierce says since the tree has annual growth rings, she can tell when the
tree got burned.

It’s one way Pierce and Wilkins reconstruct the fire history of this forest.
It’s a key to understanding how climate has affected forest fires in the past.

“I think as we move into a likely warmer and drier future, it’s going to be
increasingly important to understand the relationship between climate and
fire.”

She says climate is the primary control for wildfires. As the West warms,
there’s less control. Recently, that’s meant a lot more wildfires.

(popping sound) “There you go!” (sound of a drill bit going through the tree
with sound of birds and forest)

David Wilkins is twisting an auger into the tree.

“It’s a good upper body workout!” (laughs)

It’s a way to take a sample of the rings of this tree. Within a half-minute,
Wilkins’ auger is stuck. The tree is rotten inside. An eight-inch core is all he
gets.

(sound of drill bit coming out of the tree)

Jennifer Pierce takes a look at this sample Wilkins twisted out. The rings –
some light, some dark – reveal just how the tree has responded to moisture
and temperature.

“If you have a tree that kind of is at the edge of its comfort zone so to
speak, it will be more of a sensitive recorder of those environmental
stresses. See this one looks pretty good.”

Tree rings aren’t the only clue these scientists use to reconstruct historic
climates.

(scraping sound)

“I didn’t bring my big shovel. I kind of feel naked without it.”

Pierce scrapes away dirt and she finds bits of charcoal. She can sometimes
use charcoal for radio carbon dating. But these won’t do.

“But, um, I wouldn’t use them for dating because you want to make sure
that the charcoal is stratographicly in place and that you haven’t had
critters burrowing and mixing things up.”

Charcoal can be dated much further back than the tree rings. It helps
Pierce and Wilkins understand what happened here thousands of years
ago. With samples from other scientists, they’ll get a snapshot of ancient
climate and how it affects wildfire.

And possibly determine what climate change will mean for forests in the
future.

This week, researchers, government agencies, industry, and environmental
groups are meeting in Toronto to try to assess the overall environmental
health of the Great Lakes. The gathering is known as the State of the Lakes
Ecosystem Conference. And as the Great Lakes Radio Consortium’s Mark Brush
reports, the group says there’s good news about the amount of forestland in
the region:


The report prepared for this year’s conference says there is more forestland
in the Great Lakes Basin when comparing recent data to data collected more than
a decade ago. The report’s authors say forestland now covers a little over half
of the basin’s total land.


Constance Carpenter is with the U.S. Forest Service. She helped develop the report.
She says forests are crucial to maintaining the environmental health of the Lakes.


“They do a lot of things in terms of water quality. They’re able to provide conditions
that really contribute to watershed health in terms of, you know, moderating flood peaks,
storing water, filtering pollutants, transforming chemicals, all those things.”


Carpenter says one of the reasons forestland is increasing is because fewer people are
farming. She says as people leave behind fields and pasturelands, those lands often
convert back to forestland. The authors caution that their data did not look at whether
these forests are near lakes and streams, where their influence on the overall health of
the Lakes is greatest.
