Trees along big city streets have a rough
life. Between pollution, development,
and vandalism, street trees die off at
a pretty alarming rate. One New York
artist thinks if people knew more about
street trees, they’d appreciate them more –
and treat them better. Samara Freemark reports from New York’s “Tree
Museum”:

When artist Katie Holten was commissioned to do a piece commemorating Grand Concourse boulevard in the Bronx, the first thing she thought of was trees. The Concourse, after all, is lined with them. The problem was, no one else seemed to notice they were even there.

“I had conversations with people who were sitting under the trees for the shade. And I’d ask them about what they thought of the trees. And they would say, ‘oh, there aren’t any trees on the concourse.’ But they were sitting underneath one.”

And if people did notice the trees, they weren’t always thrilled they were there.

“Kids told me that trees should all be chopped down because they couldn’t see the view. A teacher told me that all trees were the same, that there was only one kind of tree.”

People didn’t pay much attention to the trees. When they did, they often abused them – which is pretty common treatment for the trees that line city streets. People pin street trees with flyers. They spray trees with grafitti. They chain their bikes around trees, stripping their bark. City buses jump curbs and plow into trees. And developers chop them down to put up new buildings.

“You can’t just stick a tree in the ground and hope for the best. It’s a really tough environment.”

In fact, half of all trees planted in New York City die.

Holten figured one way to protect street trees was to get people to understand all the good that trees do.

So she recruited arborists and neighbors to record messages about the Grand Concourse’s trees. She placed markers in the cement listing numbers to call to hear the recordings. And she called the whole thing the Tree Museum.


“There are 100 trees along the 4 miles. And each of the trees gets a small marker. So we can walk up here to 165th street and I’ll show you one. Here’s one of the markers- nice and dirty.”

(sound of dialing in)

We dial and hear…

“I’d like to a moment to say thank you to this tree. This tree is busy cooling the air and helping to keep the river clean. The leaves in the canopy above are pulling water out of the air, reducing humidity, like an AC.”

It’s not really clear how many people are actually calling in to the museum, or whether the recordings are changing anyone’s mind. But it’s a start.

Joyce Hoagy lives further up the Concourse. She recorded a message for tree number 31. And now she feels kind of possessive of it.

“This is my tree. It’s a honey locust and I’m identified by it.”

Hoagy says Bronx trees have been under particular threat lately. This year the city cut down hundreds of mature oaks to make room for the new Yankees stadium.

“One street had these giant oaks, and they formed this canopy. And on the hottest day of the year you could walk down…people didn’t know what they had till it was gone.”

So now Joyce Hoagy’s spreading the word about the Tree Museum too. She hopes it will give her neighbors a hundred reasons to care about trees around them – and watch out for them.

The National Park Service has a slightly embarrassing problem. It manages some of the nation’s most
environmentally valuable land – but it doesn’t have a full account of plant and animal species that live in
the parks. One remedy is the BioBlitz. A BioBlitz is a kind of whirlwind count of all the species in a

The National Park Service has a slightly embarrassing problem. It manages some of the nation’s most
environmentally valuable land – but it doesn’t have a full account of plant and animal species that live in
the parks. One remedy is the BioBlitz. A BioBlitz is a kind of whirlwind count of all the species in a
specific place. The Park Service has been co-sponsoring BioBlitzes with National Geographic. We sent
Shawn Allee to their latest:

The Indiana Dunes National Lakeshore is spread along Lake Michigan’s southern shoreline.

During this BioBlitz, scientists and volunteers fan out in teams to search the sand dunes, woods, and
grassland around here.

At first, the mood’s high, but then it rains kinda hard.

We’re supposed to be counting species for 24 hours, but at first, we can’t even get out of our cars.

(ring of a phone)

“Hello? Yeah. We’re stuck in traffic, here. We came out here and I thought we were going
out in the wrong direction.”

I hitch a ride with Dr. Patrick Leacock. He’s a mycologist, a kind of mushroom expert.

I’m actually lucky to be on his BioBlitz team, because organizers from National Geographic and the National Park Service want people to count all the species
in the park.

And they mean everything – not just plants and animals that are a cinch to find.

Allee: “Are fungi something you feel that the average person doesn’t think about when it comes
to biodiversity?”

Leacock: “Yeah, there’s people, you tell them you study mushrooms, and they talk about their
athlete’s foot, or they think there’s only six different kinds or something like
that.”

Leacock says, in fact, the Indiana Dunes Lakeshore has at least 600 fungi species. He hopes the
BioBlitz team will add to that list.

Leacock: “Here we are.”

Allee: “I’m hunting mushrooms with three trained mycologists and there are six other volunteers on my team here. One of them is Zachary Benes – he’s just 9 years old. But, I gotta say, Dr. Leacock is pretty lucky
to have Zachary on the team – since he’s found the most mushrooms of anyone on the team.”

Benes: “Is it poisonous?”

Leacock: “Nope. A real mushroom.”

Tang: “Yeah.”

Allee: “Looks like you found another one, too. Where’d you find it?”

Benes: “Over there by the wood.”

Leacock: “This is collybia sub-sulphurea. Do you know what sulfur means?”

Benes: “No.”

Leacock: “It’s a kind of a yellow-orange color. So, this might be a new record for the dunes. So that’s a good one. Was it
just the one?”

Benes: “Yeah. Just the one.”

Leacock: “It’s in good shape.”

Along the trail, I chat with Yaya Tang. She’s one of the other mycologists on the team.

Tang says she’s glad to see BioBlitz volunteers search for elusive species of bats, bugs, and fungi.

“I feel like that’s an issue with biodiversity in general. Where people care about things that are cute or
that they see immediately. Like, there’s insects, too, that don’t get a lot of attention.”

Allee: “Dr. Leacock, we’re pretty much finished here. You got this container of many varieties
of fungi we’ve collected within an hour, would you have been able to get this many
yourself? If you had come out here on your own?”

Leacock: “No. The more people you have searching, that helps a lot. Different people will see
different things, too, I think. So we’ve 14 or 15 things right in my box. We have two that might be new
records for the dunes.”

The BioBlitz at The Indiana Dunes National Lakeshore lasts another 20 hours.

A few days later, Dr. Leacock writes me.

He tells me volunteers turned up at least one fungi specimen no one had ever seen in the Dunes park.

It’s a small success – enough that National Geographic, the Park Service, and other groups are
planning more BioBlitzes across the country.

Bird Song Mystery Revealed

Scientists have come one step closer to understanding how birds
create their songs. The Great Lakes Radio Consortium’s Rebecca
Williams explains:


(dove song)


That’s a cooing ring dove. And this is a recording of special muscles
the dove’s using to control its song: (sound of muscle activity).


Those muscles are called aerobic superfast muscles. It’s a type of
muscle that has been found in rattlesnakes and some fish. The
muscles were just discovered in birds for the first time.


The research was published in the journal Nature. Coen
Elemans is the lead researcher. He says a unique quality of the dove’s
song led him to investigate it further.


“And we found that some of these doves have a trill in their song, they
make a sound something like (mimics dove song). And during this
short trill, you get elements that are so short, sometimes ten or nine
milliseconds, that I was wondering, how can this be done? This is so
fast that normal locomotory muscles you find in vertebrates cannot do the job.”


Elemans says this discovery could be just the beginning. He says
songbirds have more complex vocal systems than doves… so
songbirds could be using even faster muscles.

Essay: Tuning in to Urban Frogs

Each Spring, thousands of people spend their evenings listening to frogs and toads. It’s
not just for fun. They’re helping assess the water quality of rivers and wetlands around
the country. The Great Lakes Radio Consortium’s Ed Herrmann joined the search for
amphibians, and has this essay:


I’ve always enjoyed being outside and listening to nature. Recording nature sounds is a
hobby of mine. So when I saw an ad asking for people to listen for frogs and toads, I
thought, “All right. Beats watching campaign commercials.”


I called up Friends of the Rouge…(that’s a local group dedicated to helping out the Rouge
River watershed) and a few days later I got a package in the mail. It was full of maps and
information, and had a CD with the songs of the local frogs and toads. I studied my area,
and found some good looking wet spots where I thought they might live.


I memorized the sound of the Wood Frog (sound), Chorus Frog (sound), Spring Peeper
(sound), and American Toad. Then, on the first night when the temperature and wind
conditions were just right, I headed out to hear some frogs.


(sound of traffic roaring by)


I don’t know what I was thinking. This is suburban Detroit, not exactly a wildlife refuge.
In fact, the only animal I see is a rabbit dodging traffic. And the only thing I hear is…
(more traffic sound)


The Rouge River flows into the Detroit River and then Lake Erie. It used to be one of the
dirtiest rivers around, mainly from all the industry down by the mouth. That problem is
more or less under control but now there’s a larger one.


If you look at a map from the 1970s, you see miles of wetlands, small farms and
orchards. Today you see nonstop subdivisions and shopping malls. It might seem like
progress to you, but for the river, the constant barrage of fertilizers, pesticides, soap and
other chemicals that everybody uses to keep their suburbs looking pretty is a lot worse
than an occasional dose of battery acid from a factory. Also having acres of concrete
instead of wetlands means there’s nothing to soak up and filter the water, which means
after a big rain, it floods. It’s obvious this river needs some help.


(sound of river)


In 1998, volunteers began surveying the frogs and toads in the Rouge watershed. These
creatures were chosen because they sing, so they’re easy to track. The reason they’re
good indicators is that, like other amphibians, they absorb water through their skin. That
means they get poisoned by everything that we in the civilized world pour into the water.
Plus, their eggs hatch in water and their larvae (the tadpoles) live in water. It’s pretty
simple: if the water is good, there’s plenty of frogs and toads. If not, they disappear.


So, night after night, I’m out there listening. Listening in the dark. Listening hard.


Not a peep.


I’m beginning to think that the price of all these well-manicured lawns is a silent spring.
Then finally one night, (sound of American toads) the good old American toad! All
right, it is the most common species around, but at least it’s a start.


(sound of chorus frogs and green frogs)


A few weeks later, I join a group at a “mitigated” wetland. That means that when a
developer decided that a real wetland would be the perfect place to build condos and a
golf course, the government said, “Sure, go ahead. Drain it. Just be sure to dig a hole
over here and fill it with water.” Now, five years later, some frogs have moved in and
seem to be fine.


But they still have a little problem…


(jet roars overhead, followed by a few green frogs)


Ah, location, location. This new wetland is right
next to the airport.


Now, the reason these frogs sing is to attract a mate. So if nobody hears them, there are
not going to be any tadpoles to make next year’s frogs. In order to survive, they need not
only to sing, but to be heard.

Working From Home

The gift-giving season has come and gone. Some folks ended up with sweaters that were two sizes too large; some folks got sparkly baubles; and lots of people were the beneficiaries of gifts promising to simplify their lives – including their work lives. With millions of Americans working out of their homes, Great Lakes Radio Consortium commentator Julia King thinks home-office life after the holidays is going to be smooth sailing! Or is it?

Or is it?


Testing, testing, one, two, three.


This is great. I’m standing in my living room right now because my generous, genius husband got
me recording equipment for Christmas. I’m his very favorite NPR commentator. I think.


So, I used to have to go to an actual studio for this kind of thing. (“Look at my picture,
Mommy!”) Not now, honey. I had to get in my car (and burn fossil fuel), drive miles away
(sometimes in snow or pouring rain) and then (VIOLIN PLAYS IN BACKGROUND) I’d hope
that the engineer would show up.


Hey, Sweetheart. Mommy’s working here. Can I get a little cooperation? Thanks.


Anyway, one of the studios had this weird hum. We never could figure out exactly what it was…
(MAN YELLS QUESTION IN BACKGROUND) I think I saw it in the upstairs bathroom.


I remember once I brought a big wool blanket into the studio and we hung it over some buzzing
generator but it…


(PHONE RINGS)


Hello. Oh, hi. What’ cha doing? Oh yeah. That’s too funny. Hey, can I call you back? I’m
actually recording right now. Uh huh. No. It’s serious, high-quality stuff. Stuart got it for me
for Christmas. Yeah. Isn’t that great? Okay, I’ll talk to you later. Bye.


So the wool blanket didn’t work. And the other studio was, well, let’s just say we had a
minor disagreement about my importance. You know how that is.


Generally speaking, the only downside to this whole commentary thing has been the recording
aspect. Now it’s like all my problems (DOG BARKS) are solved. Can somebody let the dog out?
Now I’m going to be working all the time. Wow. I recommend this set up to anybody who’s
considering working for radio.


This is fabulous. I wonder what great idea my husband will come up with next year for
Christmas. I hope he gets me a snow-cone maker.

Noise Pollution Dampens the Sounds of Nature

A man who listens to the sounds of nature for a living…says we’re
missing a lot. He thinks because of noise pollution and because we’re
disconnected from wildlife…people often go through life without hearing
much of the rest of the living world. The Great Lakes Radio
Consortium’s Lester Graham reports:
