2014-07-30. U.S. advances plan to reintroduce wild bison herds outside Yellowstone. Excerpt: New herds of genetically pure wild bison may once again roam vast expanses of the American West where the iconic animal has been absent since the end of the 19th century, under a tentative plan federal officials advanced on Wednesday. The proposal, for which Yellowstone National Park officials have begun seeking public comment, is almost sure to draw staunch opposition from ranchers concerned about disease, competition for grass and property destruction from straying bison. Yellowstone is now home to more than 4,000 bison, or buffalo, constituting the bulk of the country's last pure-bred population of the animals. Dozens from the Yellowstone herd have been relocated to two Montana American Indian reservations in recent years. ...A recent U.S. Interior Department report on bison concluded they could potentially be reintroduced to swaths of public lands it manages in states such as Colorado, Arizona, New Mexico, Nebraska and South Dakota, without posing a risk to livestock. The chief concern is brucellosis, an infection that causes stillbirths in cows and may have been transmitted to roughly half the bison in Yellowstone from exposure to cattle. Park wildlife managers are eyeing a plan that would start by quarantining dozens of bison for several years to prevent them from contracting the disease. Those animals shown to be free of brucellosis could then be considered for relocation to establish controlled herds elsewhere, said David Hallac, chief of Yellowstone's science and research branch. ...Millions of the powerful, hump-shouldered animals once roamed the plains west of the Mississippi until systematic hunting drove their numbers to the fewer than 50 that found refuge in Yellowstone in the early 20th century.... http://www.reuters.com/article/2014/07/31/us-usa-bison-yellowstone-idUSKBN0G001E20140731.

2014-05-21. Return of the European Bison. Excerpt: ...the first European bison about to set their hooves in this remote Romanian valley in the southern Carpathian mountains for two centuries, wait in the shadows of a huge trailer. The forest, already home to bears and packs of wolves, is the final destination for 17 of Europe's largest land mammal, some of whom have been travelling hitched to lorries for five days from as far as Sweden. It will be their first time out of captivity. The release of the animals into the wild is one of the biggest in Europe since reintroductions began in the 1950s, establishing wild populations in Poland, Slovakia, Ukraine, Romania, Belarus, Russia, Lithuania, and Kryygzstan. More will be reintroduced each year, with an aim of having 500 in the mountains eventually. Bison bonasus was driven to extinction in the wild across Europe in 1927 after decades of decline from hunting and habitat loss. But it has become that rare endangered species: a conservation success story. There are now thousands in the wild, all descended from the 54 individuals in captivity when the last wild one was killed in Poland's Bialowieza forest. ...There are over 5,000 European bison, with about 3,200 in the wild.... http://www.theguardian.com/environment/2014/may/21/-sp-european-bison-europe-romania-carpathian-mountains - By Adam Vaughan, The Guardian.

Excerpt: Yellowstone National Park transferred 20 bison to a Montana Indian tribe for slaughter on Wednesday, marking the first such action this winter under a plan to drastically reduce the size of the largest genetically pure bison population in the U.S. ...Five more bison that had been captured were to be turned over to the U.S. Department of Agriculture on Thursday for use in an experimental animal contraception program, said park spokesman Al Nash. Yellowstone administrators plan to slaughter up to 600 bison this winter if harsh weather conditions inside the 2.2-million-acre park spur a large migration of the animals to lower elevations in Montana. It's part of a multiyear plan to reduce the population from an estimated 4,600 animals to about 3,000, under an agreement between federal and state officials signed in 2000. ...James Holt, a member of Idaho's Nez Perce tribe and board member for the Buffalo Field Campaign, said the park's population target was an arbitrary number that threatens to infringe on treaty hunting rights held by his and other tribes ... historically depended on them for food and clothing. ...But Montana's livestock industry has little tolerance for bison because of concerns over disease and competition with cattle for grass.... http://abcnews.go.com/US/wireStory/yellowstone-bison-slaughter-begins-22487724.

2013-10-26. Vision of Prairie Paradise Troubles Some Montana Ranchers. Excerpt: MALTA, Mont. — On fields where cattle graze and wheat grows, a group of conservationists and millionaire donors are stitching together their dreams of an American Serengeti. Acre by acre, they are trying to build a new kind of national park, buying up old ranches to create a grassland reserve where 10,000 bison roam and fences are few. ...“It’s a once-in-a-lifetime opportunity,” said George E. Matelich, the chairman of the conservation group, American Prairie Reserve, .... The trouble is many ranching families here in northern Montana say it is not a project for them. As the reserve buys out families and expands its holdings — it now has about 274,000 acres of private ranches and leased public lands — some here are digging in their heels and vowing not to let their ranches become part of the project. ...Officials at the American Prairie Reserve say they have done everything possible to be good neighbors and have not foisted their vision on anyone. They have installed electric fences to ensure that their 275 bison do not roam onto other people’s property. They allow hunting on the land. They lease back some of their land to allow ranchers to graze their cows. ...The reserve’s goal is to revive a landscape that existed when Meriwether Lewis and William Clark passed through in the early 1800s. They have taken down 37 miles of fence. They have replanted some tilled ground with native grasses. They have pulled down barns and sheds and cleared away heaps of trash.... http://www.nytimes.com/2013/10/27/us/vision-of-prairie-paradise-troubles-some-montana-ranchers.html.

2013-03-13. German Prince Plans To Put Bison Back In The Wild | Soraya Sarhaddi Nelson, NPR. Excerpt: A small herd of European bison will soon be released in Germany's most densely populated state, the first time in nearly three centuries that these bison — known as wisents — will roam freely in Western Europe. The project is the brainchild of Prince Richard of Sayn-Wittgenstein-Berleburg. He owns more than 30,000 acres, much of it covered in Norwegian spruce and beech trees in North Rhine-Westphalia. For the 78-year-old logging magnate, the planned April release of the bull, five cows and two calves will fulfill a decade-old dream. But the aristocrat's neighbors aren't all thrilled about his plan to release wisents, which have been living in an enclosure on his property for three years. They are slightly taller than their American cousins and weigh up to a ton. Questions remain about who will foot the bill if the European bison damage property or injure someone. ...European bison are not the first animals Prince Richard has brought back to the region. His estate is rife with gray geese and ravens, which he says he reintroduced at the request of the German government. Herds of red and roe deer, as well as wild sheep and boar, also abound on his property. ....

2012-10-22. Campaign helps European bison roam on the Russian range again. By Kathy Lally, Washington Post. Excerpt: ARKHYZ, Russia — Four startled bison backed out of their traveling crates here, looked around suspiciously for a moment, then strolled contentedly across the field. Finally, they were home, home on the range where they had been declared nearly extinct. The big and shaggy 2-year-olds, who look much like the American buffalo, had been driven 1,000 miles from a nature reserve in the Moscow region to southwest Russia, where the European bison had roamed for centuries in the woodlands of the North Caucasus mountains.They had been raised by the World Wildlife Fund, known as WWF in Russia, and brought here on a rainy day in October in yet another attempt by man to undo damage he has done to the world around him. The European bison disappeared here in 1927, was brought back in the 1970s, then killed off again in the 1990s when the people of this region, called the Republic of Karachay-Cherkessia, were thrown into poverty after the collapse of the Soviet Union. This bison meat is no gift to the palate. But people were hungry. Only 13 bison remained here in the Teberdinsky Nature Reserve, said Igor Chestin, director of WWF Russia. At that number, the bison will not breed, he said. But the four just released, and another four brought here in September, are expected to provide enough choice of mates to get some serious courting underway.

2012-04-26. As Bison Return to Prairie, Some Rejoice, Others Worry | by Nate Schweber, The New York Times. Excerpt: WOLF POINT, Mont. — Sioux and Assiniboine tribe members wailed a welcome song last month as around 60 bison from Yellowstone National Park stormed onto a prairie pasture that had not felt a bison’s hoof for almost 140 years. …The bison’s return has been welcomed by American Indians, but some ranchers are less pleased. That historic homecoming came just 11 days after 71 pureblood bison, descended from one of Montana’s last wild herds, were released nearby onto untilled grassland owned by a charity with a vision of building a haven for prairie wildlife. Some hunters and conservationists are now calling for bison to be reintroduced to a million-acre wildlife refuge spanning this remote region. … Many farmers and ranchers fear that bison, particularly those from Yellowstone, might be mismanaged and damage private property, and worry that they would compete for grass with their own herds. …When the explorer Meriwether Lewis followed the Missouri River through this region in 1805, he came across bison herds he described as “innumerable.” Just eight decades later, a young Theodore Roosevelt noted that all that remained were “countless” bleached skulls covering the Montana badlands. Scientists estimate that tens of millions of bison once roamed America, but by 1902 there were only 23 known survivors in the wild, all hiding from poachers in a remote Yellowstone valley. For decades, attempts to transplant bison from the rebounding Yellowstone herd were thwarted, despite requests from tribes to steward some of the animals. …But some say the bison on the ranches do not pose the threat that the wild ones do….
2011 December 15. Bison-to-S.D. plan hits bump. By Peter Harriman, The Argus Leader. Excerpt: Almost every winter, bison wander from Yellowstone National Park to nearby U.S. Forest Service land in Montana that was their historic winter range. They are sent to slaughter because ranchers with Forest Service grazing leases fear the bison will spread brucellosis among their cattle....
...It’s a waste of a valuable genetic resource, and the Department of the Interior, Badlands National Park and the state of South Dakota are in the early stages of investigating whether some of those Yellowstone bison that left the park... [that are brucellosis-free] can be relocated to South Dakota....
...But Montana’s colorful Gov. Brian Schweitzer is blocking the scheme. While Secretary of the Interior Ken Salazar wants to move some of Montana’s approximately 150 brucellosis-free Yellowstone bison to Badlands National Park and Great Sand Dunes National Park in Colorado, Schweitzer...wants Interior to use the Yellowstone bison to restock the National Bison Range Wildlife Refuge near Moiese, Mont....
...The ultimate goal would be to establish genetically pure bison in the Badlands National Park's southern unit on Olgala Sioux Tribe reservation land. It would lend momentum to efforts to have the first tribal national park established there....

2010 May 22. Scientists debate ‘magic number’ of wolves needed for species' survival. By Rob Chaney, The Missoulian. Excerpt:The U.S. Fish and Wildlife Service took the gray wolf off the endangered species list in 2009, with the caveat that at least 150 wolves and 15 breeding pairs endure in each of the three states in the northern Rocky Mountain population (Montana, Idaho and Wyoming). Recent surveys found at least 1,700 wolves in that area - more than enough to justify delisting.
But a coalition of environmental groups sued the government, claiming those numbers were wrong. To survive and thrive, they argued, the population needed at least 2,000 and preferably 5,000 wolves.
FWS biologists said they used the best available science to pick their number. Coalition members cited the well-established rules of conservation biology to justify their threshold. While the scientists dueled, U.S. District Judge Donald Molloy decided the case on a technicality and Congress reversed him with a budget rider. Wolves in the Northern Rockies are now delisted, but almost nobody's happy.
2010 May 19. Waterlily saved from extinction. By Pallab Ghosh, BBC News. Excerpt: …A scientist based at the UK's Royal Botanic Gardens, Kew, has prevented the world's smallest waterlily from becoming extinct.
…Two years ago, this delicate bloom went extinct in the wild due to over-exploitation of its habitat.
...Although scientists are working hard to bring many endangered plants back from the brink of extinction, they're fighting what is currently a losing battle.
…A recent study showed that world governments won't meet the internationally-agreed target of significantly curbing the loss of species by this year.
…According to James Beattie, another horticulturist at Kew, there's now a more holistic approach to preserving habitats that has been shown to work.
…"If you lose that diversity, you risk losing the chances we have of surviving on this planet as things like climate change comes into play".
2010 March 5. No Endangered Status for Plains Bird. By John M. Broder, NY Times. Excerpt: WASHINGTON — The Interior Department said Friday that the greater sage grouse, a dweller of the high plains of the American West, was facing extinction but would not be designated as an endangered species for now.
Yet the decision in essence reverses a 2004 determination by the Bush administration that the sage grouse did not need protection, a decision that a federal court later ruled was tainted by political tampering with the Interior Department’s scientific conclusions.
Interior Secretary Ken Salazar, a conservative Democrat from a Colorado ranching family, sought to carve a middle course between conservationists who wanted ironclad protections for the ground-hugging bird and industry interests and landowners who sought the ability to locate mines, wells, windmills and power lines in areas where the grouse roam....
As a compromise measure, he said, the bird will be placed on the list of “candidate species” for future inclusion on the list and its status will be reviewed yearly.
The middle-ground decision is typical of Mr. Salazar’s stewardship at the Interior Department, where he has tried to mediate between competing energy and environmental interests. Like many previous decisions, including compromises on oil drilling in Utah and habitat protection for the polar bear in the Arctic, Mr. Salazar’s action left both sides somewhat disgruntled.
Residential building and energy development have shrunk the sage grouse habitat over the past several decades, causing its population in 11 Western states to dwindle from an estimated 16 million 100 years ago to 200,000 to 500,000 today....
2010 February 1. Saving Tiny Toads Without a Home. By Cornelia Dean, NY Times. Excerpt: This is a story about a waterfall, the World Bank and 4,000 homeless toads.
Maybe the story will have a happy ending, and the bright-golden spray toads, each so small it could easily sit on a dime, will return to the African gorge where they once lived, in the spray of a waterfall on the Kihansi River in Tanzania.
The river is dammed now, courtesy of the bank. The waterfall is 10 percent of what it was. And the toads are now extinct in the wild.
But 4,000 of them live in the Bronx and Toledo, Ohio, where scientists at the Wildlife Conservation Society and the Toledo Zoo are keeping them alive in hopes, somehow, of returning them to the wild. This month, the Bronx Zoo will formally open a small exhibit displaying the toads in its Reptile House.
Meanwhile, though, the toads embody the larger conflicts between conservation and economic development and the complexity of trying to preserve and restore endangered species to the wild. Their story also raises questions about how much effort should go to save any one species....
2009 August 7. Cradle to grave: Study provides insight into evolution and extinction of vanished elephant seal colony. By Peter Rejcek, Antarctic Sun. Excerpt: An extinct southern elephant seal colony that once existed in huge numbers along sandy and rocky beaches in Antarctica has provided new insight into how quickly a species can respond to the emergence of a new habitat as climate changes — and just as quickly disappear.
That's one of the findings in a paper published in the journal PLoS Genetics in July by scientists who studied DNA sequences from the organic remains of seals found along a nearly 300-kilometer stretch of coastline in Victoria Land, just north of the U.S. Antarctic Program's McMurdo Station.
Mark de Bruyn , lead author of the study and now with Bangor University in the U.K, said the findings showed that a very large, genetically diverse breeding population of southern elephant seals existed in the Ross Sea region around 7,000 to 400 years ago.
...Climate change, the scientists say, allowed the colony to both thrive and later collapse.
It appears the ice sheet along the coast began to recede about 8,000 years ago as the interglacial climate warmed — the time period between ice ages, the most recent being the Holocene. In addition, the sea ice that would have blocked access to the beaches appears to have disappeared or declined enough for long periods of time each year to allow the seals to breed and molt on land, said Brenda Hall , a geologist with the University of Maine and a co-author on the paper.
The colony then began to decline about 1,000 years ago, according to the researchers, indicating yet another change in the climate.
"Our main conclusion is that things have cooled off in that part of the western Ross Sea over the last 500 to 1,000 years and the sea ice has re-expanded," Hall said. "We also see some evidence of glacier re-expansion at that time as well."...

1. California condor
In 1987, the last remaining 22 California condors were brought into captivity and bred at the San Diego Wild Animal Park and the Los Angeles Zoo. The scientists removed the first-laid clutches to encourage females to produce more eggs, but this meant that roughly half the young had to be reared by humans. To make them as "wild" as possible, they were fed and reared using condor-shaped hand puppets.
The human effort didn't end there. When young condors released into the wild electrocuted themselves on power lines, the scientists installed mock pylons in their cages, delivering mild electric shocks to any bird that perched on them.
Even still, the released birds did not behave "properly" – they congregated in urbanised zones and played with garbage. One researcher said it was like "putting teenagers together without adult supervision. They were behaving like a bunch of hooligans". The researchers used the remaining captive wild birds to discipline the youngsters.
The scientists' work to help the species paid off, with 322 condors known to be living with 172 in the wild as of April 2009....
2009 March 16. The Fall and Rise of the Right Whale. By Cornelia Dean, The NY Times. Excerpt: ST. SIMONS ISLAND, Ga. — The biologists had been in the plane for hours, flying back and forth over the calm ocean....
...And there, below, were a right whale mother and her new calf, barely breaking the surface, lolling in the swells.
The researchers, from the National Oceanic and Atmospheric Administration and the Georgia Wildlife Trust, are part of an intense effort to monitor North Atlantic right whales, one of the most endangered, and closely watched, species on earth. As a database check eventually disclosed, the whale was Diablo, who was born in these waters eight years ago. Her calf — at a guess 2 weeks old and a bouncing 12 feet and 2 tons — was the 38th born this year, a record that would be surpassed just weeks later, with a report from NOAA on the birth of a 39th calf. The previous record was 31, set in 2001.
...Actually, it’s one of so many good signs that researchers are beginning to hope that for the first time in centuries things are looking up for the right whale. They say the species offers proof that simple conservation steps can have a big impact, even for species driven to the edge of oblivion.
North Atlantic right whales, which can grow up to 55 feet long and weigh up to 70 tons, were the “right” whales for 18th- and 19th-century whalers because they are rich in oil and baleen, move slowly, keep close to shore and float when they die.
They were long ago hunted to extinction in European waters, and by 1900 perhaps only 100 or so remained in their North American range...
Since then, the species’ numbers have crept up, but very slowly. NOAA estimates that there are about 325, though scientists in and out of the agency suspect there may be more, perhaps as many as 400....
But “over the last four or five months there’s been a tremendous amount of good news,” said Tony LaCasse, a spokesman for the New England Aquarium, a center of right whale research....

For a man whose scholarly specialty is one of the grimmest topics on earth - extinction - Stuart L. Pimm is remarkably chipper. On a recent morning, while visiting New York City, Dr. Pimm, a 59-year-old zoologist, was full of warm stories about the many places he travels: South Africa, Madagascar and even South Florida, which he visits as part of an effort to save the endangered Florida panther. Fewer than 100 survive in the wild. In 2006, Dr. Pimm, who holds the Doris Duke professorship of Conservation Ecology at Duke University, won the Heineken Prize for Environmental Sciences, the Nobel of the ecology world.

2008 Mar 23. Anger Over Culling of Yellowstone's Bison By JIM ROBBINS, NY Times. Excerpt: GARDINER, Mont. - This was not the Yellowstone National Park that tourists see. ...more than 60 of the park's wild bison were being loaded on a semi-trailer to be shipped to a slaughterhouse. With heavy snow still covering the park's vast grasslands, hundreds of bison have been leaving Yellowstone in search of food at lower elevations. A record number of the migrating animals - 1,195, or about a quarter of the park's population - have been killed by hunters or rounded up and sent to slaughterhouses by park employees. The bison are being killed because they have ventured outside the park into Montana and some might carry a disease called brucellosis, which can be passed along to cattle.
The large-scale culling, which is expected to continue through April, has outraged groups working to preserve the park's bison herds.... ...The standoff has been made all the worse by the detection last year of brucellosis in several cattle elsewhere in Montana. Though experts believe the disease was transmitted by elk, not bison, the case has stirred passions among ranchers. Brucellosis ...when detected, requires that the cattle be destroyed. If another incidence of brucellosis appears in Montana, the state would lose its brucellosis-free status, ....
"Our interest is having a brucellosis-free United States," said Mr. Knight, the agriculture official. "The sole remaining reservoir is in the Greater Yellowstone. ...the best solution would be a vaccine for bison, .... Park officials, however, say it is not known when a vaccine, which they are researching, will be available.... In the last few years biologists have discovered that Yellowstone's bison are one of only two genetically pure herds owned by the federal government.
James Derr, a professor of genetics at Texas A&M who is studying the Yellowstone bison, said he feared that some behaviors or traits, including the propensity to migrate, could be lost with the killed bison. "The great-grandmother, grandmother, mother and daughter often travel together," he said. Killing them "is like going to a family reunion and killing off all of the Smiths. You are affecting the genetic architecture of the herd."...

But top federal officials say they are determined to resurrect it. ...The Indian Self-Determination Act of 1975 allows tribal involvement in the management of federal lands, and the Confederated Salish and Kootenai Tribes, which have strong cultural links to bison, wanted the authority to manage the refuge.
