Sturgeon spearing season is underway in some areas of the region, and hook
and line fishing is allowed at other times of the year, but to protect the
fragile population, the number of fish harvested each year is tightly
controlled. The Great Lakes Radio Consortium’s Christina Shockley
reports:


Over-fishing and habitat problems have plagued the lake sturgeon found
in the Great Lakes. Although the numbers are starting to rebound, the
U.S. Fish and Wildlife Service says lake sturgeon are still threatened or
endangered in nearly all areas the species was once found.


Ron Bruch is a sturgeon biologist with the Wisconsin Department of
Natural Resources. He says the spawning cycle of lake sturgeon is one
reason the population needs to be watched.


“Lake sturgeon don’t spawn until later in life, the females don’t spawn
until they’re 20 to 25 years old, and then they only spawn once every
three to five years.”


Bruch says only about five percent of the adult population of lake
sturgeon should be harvested each year… to avoid a population crash.
He says that compares to nearly 30 percent of the population of most
other game fish.

Forest Service Needs Better Planting Goals

The U.S. Forest Service reports more of the lands it manages are in need of reforestation. But a Congressional watchdog agency says the Forest Service doesn’t keep track of things well enough to know exactly what needs to be done to do the job correctly.

The U.S. Forest Service reports more of the lands it manages
are in need of reforestation. But a Congressional watchdog agency
says the Forest Service doesn’t keep track of things well enough to
know exactly what needs to be done to do the job correctly. The Great
Lakes Radio Consortium’s Lester Graham reports:


For the last five years, the Forest Service has seen a trend. The amount of acreage that needs to be reforested has been increasing. But that’s all it really knows.


The Government Accountability Office says the Forest Service doesn’t have the right data to know how much forest needs to be restored, which sites take priority, or to even estimate a budget. The Forest Service says part of the reason it’s having a hard time figuring out reforestation needs is that it used to calculate reforestation by the amount of trees cut down.


But recently more natural disasters such as wildfires, insect infestations and disease have complicated the calculations. The GAO recommends adjusting Forest Service data collection and policies so that trees can be planted where and when they need to be.


If there’s a delay, the harvested areas become overgrown in scrub brush. And that can cost the Forest Service more money because it has to clear the land before it can be planted in the trees that benefit wildlife and the timber industry.


For the GLRC, this is Lester Graham.

Banking on Birch Bark

A start-up company is banking on birch bark. The papery bark can be used for more than baskets and canoes. It’s used in skin creams, and scientists are studying it for use in treating skin rashes and even cancer.

A start-up company is banking on birch bark. The papery bark can be used for more than baskets and canoes. It’s used in skin creams, and scientists are studying it for use in treating skin rashes and even cancer. But Native American healers have been using birch bark for years, and some of them are worried about the supply. The Great Lakes Radio Consortium’s Stephanie Hemphill reports:


Have you ever noticed – walking in the woods – those cylinders of bright white bark, lying on the forest floor? Those are the remains of a birch tree. The inside of the tree rots away quickly, but the bark lasts much longer.


“The birch tree has some incredible defense mechanisms that protect the tree from weather, from rain, from sun, keep the moisture in, keep moisture out.”


David Peterson knows birch trees pretty well. He was a top manager at the Potlatch Paper Mill near Duluth, Minnesota. The plant processes thousands of trees every day, and burns the bark to make steam.


“I always was interested in trying to come with a way of using some of these low value waste streams generated from pulp paper mills and other places, it seemed like such a horrible waste, to take these really interesting compounds and put them in a boiler for boiler fuel.”


Peterson’s new company, NaturNorth Technologies, plans to make something worth a lot more than boiler fuel. The company has patented a process to extract large quantities of a chemical, betulin, that gives birch bark its anti-bacterial and anti-fungal qualities.


Mill workers remove bark from a tree that’s harvested for lumber or paper-making. It’s shredded into pellets, and put through a chemical process that extracts the betulin. It ends up looking something like salt.


“Here’s a sample of betulin, and you can see how bright and white it is. It’s got a chalky feel when you touch it.”


Apparently, what birch bark does for the birch tree, it can also do for human skin – protect it from the assaults of the physical world. Betulin is already used in some creams and cosmetics, but NaturNorth plans to be the first company in the world to market it on a large scale.


The idea of selling lots of betulin from birch bark makes Skip Sandman nervous. He’s a Native American traditional healer for the Mille Lacs Band of Ojibwe. He uses birch bark for medicine. He says it’s a pain-killer and blood-thinner and can be used for intestinal disorders.


“Fortunately, when people use it for medicines and stuff, one small tree does go a long way. But you might have to travel 15, 20 miles to find the right type of tree.”


Sandman says the bigger trees – ten to twelve inches in diameter – have a bigger supply of the properties he uses in medicine. And lately he’s had to go farther to find those big trees. He says that’s because timber companies have cut down so many of the big trees and now they’re working on smaller and smaller trees.


“But you see the logging trucks go by, and they’re just whacking down everything. Well they think it’s only a tree. But when the trees are gone, then what do we do?”


Sandman says in the Ojibwe creation story, each plant and animal promised to help people in some way, and birch trees offered their healing qualities. He says it’s important to use them respectfully, and not for profit, but only to help people. He says he approaches the tree with an offering of tobacco.


“I will put tobacco down and ask and talk to that tree, because it is alive.”


The folks at NaturNorth are hoping to make money from birch trees, but they’re also excited about helping people. David Peterson says he gets letters from people who want some betulin to treat a skin condition.


“When you get those letters, you can’t help but to feel that somebody out there that’s gonna benefit eventually from these compounds, I think it’s quite sobering and humbling.”


NaturNorth has started marketing betulin to cosmetics companies, and scientists are studying betulinic acid for its disease-fighting potential. Peterson says it’ll be several years before NaturNorth generates a profit.

Harvesting the Wind (Part 1)

  • Wind turbines can be both a blessing for farmers, as a source of extra income... and annoying to the neighbors. (Photo by Lester Graham)

Wind farms of huge turbines are springing up along coastlines,
windy ridges and blustery farmland. Most of us see them from a distance.
The Great Lakes Radio Consortium’s Chris Lehman recently visited some
of them up close… and has the first of two reports on wind energy:

Wind farms of huge turbines are springing up along coast lines, windy ridges and
blustery
farmland. Most of us see them from a distance. The Great Lakes Radio Consortium’s
Chris
Lehman recently visited some of them up close… and has the first of two reports on
wind energy…


If you can imagine the sight… there are 63 wind turbines scattered across the
prairie farmland,
their huge blades sweeping around, capturing energy from the wind. Each turbine is
213 feet
high. You can see them from miles around. But it isn’t until you stand directly
underneath the
80-foot long blades as they rotate in the wind that you begin to appreciate their size…


(sound of wind from underneath turbine)


“This is probably a typical day. They’re probably producing at about 30 percent of
what they are
rated at, and probably on average, for a year, this is what you’d expect.”


Christopher Moore is Director of Development for Navitas Energy. The Minnesota- based
company opened the Mendota Hills Wind Farm in northern Illinois just over a year ago.


Q: “What are some of the highest levels that you’ve reached?”


“Each turbine is capable of producing 800 kw, and there are times when we’ve had the
windfarm
working at about maximum.”


Moore says the Mendota Hills Wind Farm produces enough electricity to power about 15-
thousand homes per year. It’s the first wind farm in the state of Illinois.


Brian Lammers is a Project Manager for Navitas Energy. He says the location is
ideal since it’s
windy here nearly all year long…


“The wind here is more robust in the fall, winter and spring. So we have more
production during
those months than we do during June, July, August.”


Unfortunately, the summer months are the months that most often experience peak
demand for
electricity. Because of that, and because it takes so many windmills to generate
lower amounts of
power, it’s unlikely that current wind energy will completely replace fossil fuel
generated power.


(sound of turbines)


On the flat prairies of Illinois, the giant turbines are the tallest structures for
miles around. You
begin to wonder about things like lightning strikes…


“We might have experienced one or two last year. The turbines are protected from
lightning. The
entire wind farm is grounded, so if there is a strike typically it will just be
grounded down to the
ground grid. There’s typically no long-term damage associated with a lightning
strike. But as you
can imagine, they’re the tallest structures around so there are periodic lightning
strikes.”


Q “What about a tornado? This is tornado country…what would happen if one came
through
here?”


“I don’t know. These turbines are built to withstand everything but a direct strike
from a tornado,
so I think the same thing would happen to a wind turbine that would happen to any
large
structure if they were struck by a tornado. You’d probably have some significant
damage.”


(fade up sound inside turbine)


Inside the turbine, there’s a distinct hum as the blades whirl away at the top of
the hollow shaft.
It’s about ten feet across at the base, and a metal ladder allows anyone brave
enough to climb all
the way to the top.


Despite the hum of the turbine’s blades up close, the sound fades away just a few
dozen feet from
the tower. But noise isn’t much of a concern for this wind farm. It’s in the
middle of a soybean
field and there are no neighbors nearby.


Noise is just one of the aesthetic concerns for neighbors of wind farms. Appearance
is another.
The Mendota Hills turbines are coated with a special paint that appears white in
bright sunshine.
But when the sun’s not out, the turbines appear grey, and seem to blend in with the
cloud-covered
sky.


Dennis Cradduck has 19 of the turbines on his corn and soybean farm. He says the
wind farm
hasn’t been a problem. Of course, he’s getting paid by Navitas for allowing the
turbines on his
land. But he says the wind farm has led to an unexpected benefit: getting to meet
people from
across the country who pull off the highway for a closer look…


“We get people almost on a daily basis that drive by on the interstate and see them,
and stop and
want to look at them, and they’re amazed at them, and most—about 99 percent of them
have been
positive comments. In fact, one fellow from North Carolina stopped the other day
and said ‘I wish
we’d build more of these around the country because we need renewable energy.'”


The prospect of more renewable energy is appealing to most environmentalists. But
some worry
that wind farms can be deadly to birds. A study by the National Wind Coordinating
Committee
found that wind turbines kill an average of two birds per year.


Another concern is that windmills disrupt the scenery. But the only view around
here is farmland
as far as the eye can see. And on this brisk day, it isn’t just corn and soybeans
being harvested: it’s
the power of wind.

Clear-Cut Demonstration Angers Forest’s Neighbors

Most forests in the Great Lakes region are privately owned. That concerns the U.S. Forest Service because the agency says many forest owners don’t know how to properly manage their woodlands.

Most forests in the Great Lakes region are privately owned. That concerns the U.S.
Forest Service because the agency says many forest owners don’t know how to properly
manage their woodlands. The Great Lakes Radio Consortium’s Julie Grant reports that a
new education project that demonstrates tree-harvesting techniques has angered some residents:


(sound of chain saws)


Workers are cutting down trees in a fifty-year-old pine crop. At the same time, state
foresters are leading a botanist, a private tree farmer, and a reporter through this forest
education site. One of the foresters, Rick Miller, is directing the chain saws to show what
needs to be cut for what’s called a “crop tree release.”


“This one here we selected out with the orange flags, the trees that show the best form and
dominance in the crown. They have a nice big healthy crown. And then what we’re doing is removing
any trees that are touching the crowns of those ones that are orange, and just opening it up
to give the crown more room up there to spread out and possibly increase their growth and their
vigor.”


A forest owner who wants to make money off his pine stand might do a crop tree release to
improve the quality of the remaining timber. The bigger the tree, the more money it’s worth
to a logging company.


Heading deeper in, a crop of pine trees lined up like soldiers trails to our right, and wilder
hardwoods shade us from the left. There are signs to demarcate different timbering techniques:
improvement cut, understory removal, selective cut. Project manager Frank Corona stops at one
section of oaks, maples and cherries.


“You have small trees, medium trees, some larger trees. Trees are probably selectively
harvested in here and you have all different ages of trees in this stand…”


The cool shaded path abruptly opens up. The lush canopy is replaced by harsh sunlight.


GRANT: “Oh wow, so this is the clear-cut…”


CORONA: “This is the clear-cut.”


The forest is gone… cut to the ground. All that remains are the 120 hardwood stumps on
the torn-up dirt. Botanist Steve McKee suports construction of the demonstration site.
But he also loves trees.


GRANT: “What do you think when you see that clear-cut?”


MCKEE: “Well, clear-cuts are never pretty, ya know? So, uh, I think the most shocking thing
for me is I’ve walked in this my whole life and it was surprising. But I knew it
was coming too, so…”


But some people in the community say they didn’t know the demonstration project would include
clear-cutting older trees. Anne McCormack hikes the Mohican nearly every day, clearing trails,
cleaning garbage, or enjoying the woods. The education site has been roped off from the public
during construction. But she found out there was a clear-cut demonstration in an old growth
section of the forest.


“So, I just was… I was just shocked. I mean I can’t say anything more. I just felt
terrible for… I felt terrible for the trees that stood there since before white settlers
were even in Mohican. And there they just were bulldozed and chain cut for education.
I mean, it doesn’t add up.”


McCormack’s not the only one who’s upset. A lot of people didn’t realize this is what
the Forest Service had in mind. Back at the clear-cut site, Corona says many trees suffer
from disease when they mature to 120 years. He says it’s a good age for private land owners
to consider the clear-cut option.


“This was a time where before they would rot out or anything and we see more damage, more
susceptibility health-wise in the entire stand, we could make a harvest in here and utilize
those trees and start this whole new cycle of growth in here.”


The foresters and forest owners say clear-cutting is a viable option, and just one of the
many examples at the demonstration project in the Mohican forest.


Tree farmer Scott Galloway says people need to understand that owning a forest is another
form of family farming. For instance, he got a call recently from a man who inherited 30
acres and needed money right away. He doesn’t know how to manage his tree crop.


“Where does he go? How do you make the right decisions quickly? The faster he can make
decisions, in his lifetime with his forest, the sooner he’ll be able to enjoy the benefits
of those decisions. It’s all about forestry, wildlife, natural resources. So the more education he
can get, the better those decisions will be and the better off all of us are environmentally because of it.”


The Forest Service says a demonstration project is needed because forest acreage is getting
cut up into smaller and smaller parcels. That means the forests are owned by more and more
people who need to know how to manage their timber. The Forest Service hopes this project
will help them make better decisions.
