A new report finds an agreement among the world’s governments to protect nature is failing. Lester Graham reports on the assessment which finds more animals, forests and other habitats are being lost.
World governments signed the 2002 Convention of Biological Diversity, agreeing to protect more habitat and species that are at risk. An assessment of the progress has been published in the journal Science and it finds biodiversity is at greater risk than it was when the agreement was signed eight years ago. Matt Foster is with the environmental group Conservation International. He says despite some government efforts to protect habitat, there have been more pressures destroying habitat and biodiversity.
“And it’s a scary prospect, not just from a biodiversity side, but considering that there are so many vulnerable people around the world for whom the services provided by nature and biodiversity are essential such as for water, for food and all of us depend on nature and forests especially to try to mitigate climate change.”
Foster says much more needs to be done by governments and the private sector to preserve natural areas and protect species.

For decades now, we’ve been pushing
the limits on how much fish we can
catch. Mark Brush has been looking
at the recent trends:
If you look at the news, you get the picture. Declining salmon runs in British Columbia. Herring season cancelled along the West Coast. And tuna populations nearing collapse.
Over-fishing and damage to the environment are big problems in the world’s oceans, but you see declining fish stocks in the nation’s freshwater bodies as well.
Bill Carlson’s family has been fishing the Great Lakes since the 1870s. They catch fish called chub. But the chub are in serious decline.
“The chub population has just taken a real plunge, but we’re not sure what we’re experiencing is just a change in their habitat.”
These fish go through boom and bust periods. But since the chub’s main food source has disappeared, some biologists think the chub will have a tough time making a comeback.
So between over-fishing and environmental damage, the only good news seems to come from areas where there are strict rules in place – giving these fish stocks a chance to bounce back.

A federal judge says the Obama
Administration soon has to come
up with a plan to restore endangered
salmon runs to the Pacific Northwest’s
biggest rivers. Ann Dornfeld went
gill net fishing on the Columbia
River to find out what’s at stake:

Gary Soderstrom is a fourth-generation Columbia River salmon fisherman. Even though it’s his work, on a sunny summer day there are few places he’d rather be than casting a gill net on this tranquil bay near the mouth of the Columbia.
“Just being this far from the dock, it’s just a whole different world! All the nights and the days I’ve put out here, I still feel good when I get out here.” (laughs)
Soderstrom – or Suds, as he’s better known – says gillnetters today catch salmon pretty much the same way his great-great-grandfather caught them. The main difference today is motors help fishers lay out and reel in their nets.
(sound of reel squeaking as net is laid)
“See how he’s layin’ up the bank here, and then he’s gonna go across. That’ll create a trap for the fish if he leads ’em over to the beach, and they might get confused.”
The technique might not have changed much. But this river has. These days, a dozen species of salmon and steelhead on the Columbia are listed as endangered. One of the biggest factors is the hydroelectric dam system that provides most of the power to the Pacific Northwest. Those dams keep young salmon from making it to the ocean. Suds says that’s why his son won’t be a fifth generation fisherman.
“There used to be several thousand fishermen on the Columbia at one time. Now there’s a couple hundred of us that are still active. Most guys like my son and them have went and got other jobs to try and raise families on.”
Federal law requires the government to restore the endangered salmon runs. For years, fishers and environmental groups have been calling for the removal of four dams on the Snake River, a tributary of the Columbia.
But the Clinton and Bush Administrations backed other plans to restore salmon runs. Those plans ranged from spilling a small portion of water through the dams to trucking baby salmon around the dams. Federal courts rejected those plans as insufficient. Now a federal judge has told the Obama Administration it has until mid-September to come up with a plan that goes far beyond the scheme President Bush proposed last year.
Ann Dornfeld: “What do you think is the chance that they’re gonna take out the dams?”
Gary Soderstrom: “Well, about like me winnin’ the Powerball! (laughs) I mean, don’t think it’s ever gonna happen, but realistically, it’d work.”
Suds says he’d also like to see tougher restrictions put on farmers who irrigate their crops with water from the Columbia.
“Irrigation systems, a lot of them are still water hogs. I think they should be forced into using the least amount of water they can get by with.”
It’s been about 15 minutes, and it’s time to reel in the nets.
(sound of reeling in nets)
We’ve brought in one 17-pound coho.

But like most of the other fish caught on the Columbia these days, it was raised in a hatchery upstream.
Suds says for years he’s been volunteering his time on advisory councils and boards throughout the state to try to restore the habitat that once brought millions of salmon down the river the natural way. But what he’d really like to do is meet with President Obama and explain the river’s history to him firsthand.
“But in my situation, being a peon fisherman, you’ll never get to talk to a guy like him. Y’know, if you could bring him out here and show him what I’ve shown you today, maybe he’d have a clearer understanding of what’s going on out here.”
Suds Soderstrom says he wants the president to make good on his promise to let science dictate his policies, rather than politics – which always seem to favor development.
“Sooner or later you’re either gonna have fish or people. And the people seem to be winning.”
The new Administration has until September 15th to propose its plan to save endangered salmon. The federal judge who’s been overseeing the process for years has made one requirement: this time, the plan has to work.

Commercial fishing in the oceans of the US has done a lot to reduce
accidentally catching marine mammals such as dolphins. But there are
still problems. Ari Daniel Shapiro reports on concerns about one kind
of tropical dolphin called the false killer whale:
Jim Cook has been a fisherman in Hawaii for 18 years.
“You know, it used to be real simple: catch a fish, sell it, and go
back out and try and catch another one.”
Now he owns a company that operates six fishing vessels. Cook’s
ships catch deep swimming sashimi-grade tuna that ends up in sushi
restaurants across the US. They use a technique called longline fishing.
“We have around 45 miles of mainline to which we attach floaters
and 2200 to 2500 baited hooks.”
“The regulations imposed on the Hawaii longline fishery are
probably the most restrictive regulations on any longline fishery in the
world.”
That’s Bill Robinson. He’s an administrator with the National
Marine Fisheries Service. And these regulations he’s talking about are
meant to reduce bycatch. That means catching marine animals other than
the tuna. As a result of these policies, sea turtle bycatch has dropped
by more than 90-percent and seabird bycatch by 95-percent.
Things are looking up, but now there’s another problem. The numbers of
another kind of animal – the false killer whale – are declining. No one
knows why they’re disappearing. It might be related to longline
fishing, but it’s just not clear.
Robin Baird’s a biologist with Cascadia Research.
“There’s a whole variety of lines of evidence that imply the false
killer whale population around the main Hawaiian islands has declined
dramatically over the last 20 years. And I think it’s clearly the most
serious conservation or management issue for whales and dolphins in
Hawaiian waters today.”
Baird thinks the decline is partly related to fewer numbers of tuna
and other species false killer whales eat. He also suspects that the
false killer whales might be moving farther offshore, where they could
get hooked when trying to eat the tuna caught by the longline fishery.
So the question is: should the National Marine Fisheries Service come up
with even more regulations for the longline fishery in case more false
killer whales move offshore looking for tuna.
Bill Robinson with the Fisheries Service isn’t so sure that they
actually go that far offshore.
“That’s speculation, and it may or may not be true. What we
don’t really know is what the range of each population is.”
So, really, at this point, it’s anyone’s guess why the false killer whale numbers are declining.
The biologist, Robin Baird, is concerned that nothing’s being done.
“Unless something is done to change the factors that are
influencing the population, it probably will continue to decline.”
The environmental group Earthjustice and a coalition of
conservation groups have sued the National Marine Fisheries Service over
failing to develop a plan to protect the false killer whales.
The agency has not responded officially to the lawsuit yet. But Bill
Robinson says an action plan is in the works.
“Hopefully by the fall, we’ll be able to not only appoint the
team, but have the team begin work on a take recovery plan that will
make recommendations to the agency to reduce the incidental take of
false killer whales in the fishery.”
Such a plan might end up costing the commercial fishers money. But
Jim Cook says he’s willing to pay. That’s because false killer whales
pick fish off his lines. They eat the caught tuna before the fishers
can haul them in. That can mean a lot of lost income.
“We would very much welcome any methodology almost
irrespective of cost because we’re suffering quite a bit economically as
it is.”
But the National Marine Fisheries Service first has to find that
methodology.

A new report warns that nearly a third of North America’s bird species are
in trouble. And it says habitat loss is to blame. The Great Lakes Radio
Consortium’s Rebecca Williams has more:
National Audubon Society researchers analyzed data on more than 650 bird
species. They found that since 1966, certain bird populations have been
declining in all habitats.
Birds that thrive in grasslands are especially at risk. The study found 70
percent of grassland bird species are declining significantly.
Greg Butcher is the study’s lead author. He says today’s farming practices
have reduced available bird habitat.
“In the 50’s, field sizes were small, there was a lot of variety of crops
being planted, there were a lot of hedgerows and field edges that were good
for bird populations. Most farming is done road to road now. And so, in the
1950’s, agricultural landscapes were very favorable for bird populations,
and today, they’re just not.”
Butcher says creating grass buffers around farm fields can help some
grassland species. But he says other species need larger areas of land to
succeed.
