Un Report Gives Region a Grade

The United Nation’s Environment Program says the Great Lakes are cleaner.
But a new report says the U.S. and Canada need to do more to prevent
problems due to urban growth, agricultural runoff and invasions of exotic
species. The Great Lakes Radio Consortium’s Lester Graham reports:


The U.N. report looks at what’s happened to the environment in the U.S. and
Canada for the last 30 years. It finds that there’s been significant progress
in protecting the ozone layer, reducing smokestack and auto emissions, and
slowing the loss of wetlands and other wildlife habitat.


The report in particular notes the progress made in cleaning up the Great Lakes. It
states that since 1972, the use, generation and release of several toxic
chemicals into the Great Lakes has been reduced by 71 percent. But, it also
finds that the two countries have not done a good job of stopping exotic
species such as the zebra mussel from damaging the environment of the lakes,
and it ticks off a list of toxic pollution problems from urban areas and
farms. The report concludes that North America’s global impact is disproportionately large compared to other countries in the world.

An International Wildlife Refuge?

An effort to create North America’s first international wildlife refuge is gathering speed. The refuge will be a partnership between Canada and the U-S. The Great Lakes Radio Consortium’s Mark Brush has details:


The Detroit River was once home to a thriving set of coastal wetlands and marshes. It was an area teeming with wildlife. But after more than a century of development – most of that habitat has been lost. The proposed international wildlife refuge hopes to turn back the pressures for more development.


The refuge would include the Canadian and U-S sides of the lower Detroit River – lands from the coal-choked Zug Island to the mouth of Lake Erie.


If established, the refuge will be a patchwork federal, state, and privately owned land. And so far, they’ve had some success. Several small islands have been donated or are being bought for inclusion into the refuge.


The first step will be to set up the boundaries of the refuge. Once established, funds may be appropriated for things like buying more land, establishing conservation agreements, and re-creating wildlife habitat.

Bear Hunt Casts Wider Net

The number of black bears is increasing across North America, but the fastest-growing bear populations are in the Great Lakes region. The most recent estimates put the region’s population at over 60,000. In Minnesota, the bear population has quadrupled in the past two decades. Wildlife managers think the population is getting too big, and this fall the state is trying to help hunters kill more bears. Minnesota is offering a “two-for-one” deal on bear permits. Hunters can buy one license, and kill two bears. And the state is opening hunting season early, in the last week of August. Some people are upset. They say there’s no need to increase the bear kill. The Great Lakes Radio Consortium’s Chris Julin has the story:

Bird Decline Tied to Exotics

According to the National Audobon Society, some species of
songbirds have experienced a 30 percent decline in their population
over
the past decade. Now, there’s evidence that non-native plant species
may
be contributing to the problem. The Great Lakes Radio Consortium’s
Karen Kelly reports:

According to the National Audubon Society, some species of songbirds have experienced

a thirty percent decline in their population over the past decade. Now, there’s

evidence that non-native plant species might be contributing to the problem. The Great

Lakes Radio Consortium’s Karen Kelly reports:


American robins and wood thrushes like to build their nests in shrubs. Typically, they

choose tall bushes with long thorns that keep predators away. But as those plants are

replaced by non-native species, the birds are forced to move into the new shrubs. And

that makes them vulnerable to predators.


Christopher Whalen is an avian ecologist with the Illinois Natural History Survey. His

study found birds that nest in exotic shrubs were twenty percent more likely to lose

their eggs to a predator.


Because of the different way these plants grow, the exotic shrubs provide a

suitable-looking confluence of branches at a lower height above the ground. So, nest

height drops a meter and a half to two meters on average.”


That makes it easier for raccoons to invade. Whalen’s study focused on Illinois, but

he says birds are doing this throughout the Northeast and Midwest.

Low Water Levels Create New Habitat

There’s been a lot of concern about falling water levels on the
Great Lakes. Some of the lake levels have dropped more than a foot.
However… new wildlife habitat is being formed as the water levels
fall.
The Great Lakes Radio Consortium’s Lester Graham reports:

Native Landscapers Go Wild

  • Lisa Johnson shows off a rough blazing star, a native prairie plant. Johnson is a member of Wild Ones - Natural Landscapers, Ltd. The group encourages growing native plants to save the genetic diversity and to attract wildlife.

More and more backyard gardeners are tending plants they once
considered to be weeds. The Great Lakes Radio Consortium’s Lester Graham
reports… these backyard naturalists are creating tiny natural areas to
save the plants and attract wildlife:

Artificial Reefs: A Help or a Hindrance?

Artificial reefs are being built in the Great Lakes to attract fish.
Sport fishing groups like them because the reefs make it easier to catch
fish. However…the Great Lakes Radio Consortium’s Lester Graham reports
some conservationists are concerned the artificial reefs could destroy
natural habitat:

Reintroducing the Otter

A coalition of industries, institutions and individuals is making sure
that a piece of their state’s natural heritage is returned. The Great
Lakes Radio Consortium’s Bill Flynn reports on the
three-hundred-thousand dollar New York River Otter Project:

Golfing With Wolves

Animals often lose their natural habitat when rural areas are
developed. But sometimes those new developments can provide them with
even better access to food and shelter…and that can cause populations
to explode. In Canada’s Banff National Forest, the problem is elk. One
of their favorite hang-outs is the golf course, where they eat
everything in sight, and leave behind mounds of dung… so the town put
together an elk advisory board to study the problem, and now they may
have found an innovative solution. The Great Lakes Radio Consortium’s
Wendy Nelson reports:

Urban Trapping

As human populations grow and sprawl out from cities, the number of
human/animal conflicts increases. But it’s creating a healthy demand
for a growing industry. The Great Lakes Radio Consortium’s Wendy Nelson
