Newhall Ranch developers must not harm California condors, feds say.

CALIFORNIA CONDOR NEWHALL
The U.S. Fish and Wildlife Service on Tuesday said it would not tolerate the harm or killing of an endangered California condor during construction of a proposed Newhall Ranch community of 60,000 residents along the Santa Clara River.
In a long-awaited, 178-page opinion, the agency also said, however, that it would allow the developer to capture and relocate one condor over the next 25 years, if necessary, according to agency wildlife biologist Rick Farris.
“We anticipate that there might some occasion over the 25 years in which a California condor may become attracted to some human activity such as construction of a house,” Farris said. “If it can’t be hazed off the property without hurting it, then they will have to capture it.”
“Additional condors that become habituated to such activities, however, would not be covered by the exemption."
The federal Environmental Protection Agency has questioned whether the Army Corps of Engineers, which is set to permit the development's construction 35 miles northwest of downtown Los Angeles, has adequately considered its impacts on an array of rare and endangered plants and animals.
The corps is expected soon to issue a Clean Water Act permit authorizing the developer, Newhall Land, to use 20 million cubic yards of excavated soil to fill in wetlands in areas to be developed over the next 20 to 30 years on the 12,000-acre ranch.
Of particular concern to the EPA are plans to fill in much of Potrero Canyon, which includes roosting and foraging grounds for condors.
Adam Keats, spokesman for the Center for Biological Diversity, said, “I’m pretty happy to hear that the agency will is not going to let them harm one of these magnificent birds.”Los Angeles Times...

Brown pelican long a symbol of survival

(CNN) -- Long before the brown pelican came to symbolize the tragedy of the Gulf oil spill, the giant bird stood for something much greater: survival against all odds.
The state bird of Louisiana was nearly wiped out by pesticides in the 1950s and 1960s. Yet after decades of conservation efforts, the brown pelican just last year was removed from the endangered species list.
"At a time when so many species of wildlife are threatened, we once in a while have an opportunity to celebrate an amazing success story," Interior Secretary Ken Salazar declared on November 11. "Today is such a day. The brown pelican is back."
Now, eight months later, Louisiana Gov. Bobby Jindal stands on the deck of a boat near Pelican Island off the Louisiana coast. He's surveying efforts to protect the state's wetlands. He's ordered the National Guard to begin building barriers in the ocean to try to stop the oil from reaching shore.
Yet Jindal pauses to talk about the brown pelican. The recent images of pelicans, coated in BP oil like grotesque statues, have taken on the symbolism of the spill. Louisiana has long been known as the "Pelican State," with the bird gracing the state flag.
"Here's what's really sad," Jindal said. "For every one of those mother adult pelicans you're saving, there are many more back there that you can't get to. And for every mother pelican you're saving, there may be a nest, there may be eggs that can't be saved.
"And that's the tragedy in this: That for every animal we see, what's this oil doing to their young? What's this oil doing to their life cycles?"
The recovery of the pelicans, before the spill, was largely attributed to the ban of the toxic chemical DDT in 1972. The pesticide traveled down the Mississippi River and into the Gulf of Mexico.
Three species were most affected: the brown pelican, the bald eagle and peregrine falcon. A component of DDT accumulated in each of those birds and, as a result, it affected the strength of the eggs they laid.
"The result was that you had thinner egg shells in the nest. During incubation, all the species had the tendency to break the eggs more easily," said Dr. Doug Inkey, a senior scientist for the National Wildlife Federation. "This resulted in a huge population decline in all three species."
The bald eagle, peregrine falcon and brown pelican were all listed on the endangered species list. In the case of the brown pelican, wildlife officials in Louisiana and Florida teamed up to help save the bird over a 13-year period. A total of 1,276 young pelicans were captured in Florida and then released at three sites in southeastern Louisiana, according to the Interior Department.
"When their populations were low, we brought in those brown pelicans from Florida," Jindal said. "Now, when we capture them oiled, clean them up and rehabilitate them, we have to release them back in Florida to get away from this oil."
The U.S. Fish and Wildlife Service has deployed more than 450 people across the Gulf to respond to the nation's worst environmental disaster. As of Monday, the oil threatened 36 National Wildlife Refuges. Nearly 1,200 birds have been saved, including 728 in Louisiana.
Ron Britton of the Fish and Wildlife Service gave a CNN crew a tour of the marsh islands near Grand Isle, Louisiana, a prime breeding ground where oiled pelicans have been spotted.
"What you're trying to do is get in and get those as quick as you can," Britton told CNN's Anderson Cooper. "But the ones you're missing have less chance each night you can't get back. And the ones we don't get back, we're pretty sure are going somewhere and not surviving."
Oil affects pelicans in various ways. The birds' feathers interlock in a way that helps regulate cooling and, when oil soaks their feathers, the birds lose the ability to do that, biologists say.
"Brown pelicans dive into the water for fish. As they break the water, that's one of the ways they contact the oil. Then, once it's on their feathers, the birds preen daily," said Jennifer Coulson, president of the Orleans Audubon Society.
"When they're preening, they ingest all the BP oil. And so, that's another way they get sick and die."
Inkey of the National Wildlife Federation added, "When they get back to their nests, then they rub some of the oil from their chests to their eggs -- and oil on eggs is not a good mix. It's usually deadly for the developing embryo."
Inkey recently visited a brown pelican-nesting habitat along the Louisiana coast. Hundreds of the birds lived together in nests about 6 feet high in mangrove trees along the shore. There were two layers of protective booms surrounding the island that were "close to being worthless."
"We saw more oil inside the booms than we saw outside the booms," he said. "It was surrounded by a bathtub ring of oil."
His first thought: What's going to happen to the pelicans this year?
What's this oil doing to their young? What's this oil doing to their life cycles?
--Louisiana Gov. Bobby Jindal
"This is the worst-case scenario: It's during breeding season," he said. "We're likely to lose a whole generation of young of many different species. ... It only takes once for a bird to really get messed up in oil for it to have an effect on the nesting success."
He and other biologists said it's far too early to know the full effect of the oil spill on the larger population of brown pelicans -- and whether the bird would ever make it back to the endangered species list. "It would be premature to suggest that," Inkey said.
Biologists said the pelican -- known for its long beak with a hooked tip and its 6-foot wingspan -- is better equipped to survive than smaller birds that ingest oil in greater proportion to their size. In addition, there are five species of sea turtles in the Gulf, and all are endangered or threatened.
"A sea turtle hatchling does not stand a chance," Inkey said.
Regardless, it's a dire situation for all types of wildlife in the region, biologists said.
Yet it was the images of the oil-soaked pelicans that brought home the scope of the disaster -- and its potential devastating consequences. The birds survived DDT, the constant erosion of Louisiana wetlands and Hurricane Katrina.
Inkey already had returned from his visit when the photos first appeared. "I got sick in my stomach," he said. "I had seen oiled pelicans, but not like that. The ones I saw were simply gray. These were just heartbreaking."
He paused. "How do you explain a picture like that to young children and get them to understand that this is something, although unintentional, that man caused?"

Four highly endangered mountain gorillas have been found dead in Rwanda's Volcanoes National Park, likely because of extreme cold in their mountain habitat, experts said Thursday.
Some of the group were found still alive but dying earlier this week by trackers from the Karisoke Research Centre in the mountains of north-west Rwanda.
"While the cause of death has yet to be determined, the gorillas are thought to have died because of the extreme cold and rainy conditions," the World Wildlife Fund said in a statement.
"The gorillas? current range is high on Mount Karisimbi, and at high altitude it will be even colder," WWF said.
The wildlife group said there were no signs of foul play but that the dead gorillas, one female and three infants, have been sent for autopsy to determine the cause of death.
The four were part of a research group called Pablo.
"Unless the post mortem results show something contagious, it may be just a natural event ... likely to be down to the cold weather," said Ian Redmond, a gorilla expert who is chief consultant with the UN's Great Ape Survival Partnership.
"As in human populations, an extreme cold spell can be the cause of death for weak or ill individuals who might have otherwise recovered," Redmond told AFP.
Karisoke research centre was founded in 1967 by Dian Fossey, the US primatologist who brought mountain gorillas to the attention of the public and who was brutally murdered in the Virunga National Park in 1985.
"The sudden death of the four is not only a great shock but also a big loss for Rwanda and for the whole conservation team," said Rica Rwigamba, a tourism and conservation official at the Rwanda Development Board.
The Virunga volcanoes on the borders of Rwanda, Uganda and the Democratic Republic of Congo are home to about half of the world's 700 mountain gorillas (Gorilla beringei beringei). The other half live in Uganda's Bwindi Impenetrable Forest.
Gorilla tracking is a major draw for tourists in Rwanda, with visitors paying 500 dollars for a permit to spend an hour with the primates in their bamboo forest habitat.
