New report: boreal forests contain more carbon than tropical forest per hectare

2009-11-12T05:00:00Z

A new report states that boreal forests store nearly twice as much carbon as tropical forests per hectare: a fact which researchers say should make the conservation of boreal forests as important as tropical in climate change negotiations. The report from the Canadian Boreal Initiative and the Boreal Songbird Initiative, entitled "The Carbon the World Forgot", estimates that the boreal forest—which survives in massive swathes across Alaska, Canada, Northern Europe, and Russia—stores 22 percent of all carbon on the earth's land surface. According to the study the boreal contains 703 gigatons of carbon, while the world's tropical forests contain 375 gigatons.

Tiger success story turns bleak: poachers decimating great cats in Siberia

2009-10-18T17:52:00Z

There were two bright spots in tiger conservation, India and Russia, but both have dimmed. Last year India announced that a new survey found only 1,411 tigers, instead of the previous estimation of 3,508, and now Russian tigers may be suffering a similar decline. The Siberian Tiger Monitoring Program—a collaboration between the Wildlife Conservation Society (WCS) and several Russia government organizations—has found evidence that after a decade of stability the Siberian tiger's population may be falling. This year's annual survey, which covers only a portion of tiger habitat in Russia, found only 56 adult tigers: a forty percent decrease from the average of 95 tigers. While the cause of this year's decline may be weather-related, researchers fear something far more insidious is going on.

500 scientists call on Quebec to keep its promise to conserve half of its boreal forest

2009-09-13T20:03:00Z

This March, the Canadian province of Quebec pledged to conserve 50 percent of its boreal forest lying north of the 49th parallel, protecting the region from industrial, mining, and energy development. On Thursday 500 scientists and conservation professionals—65 percent of whom have PhDs—sent a letter to Quebec's Premier Jean Charest calling on him to make good on his promise.

Retailers Costco and Amazon.com flunk sustainable paper use, WalMart and Target fare little better

2009-08-27T15:56:00Z

Every year forests are destroyed for the production of paper: habitat is lost, greenhouse gases are released, species are impacted, and fresh water sources damaged. Some companies have begun to move towards more sustainable paper production, seeking paper sources stamped by the Forest Stewardship Council (FSC) and increasing the use of recycled paper, however other companies in the industry have yet to change their way. The 3rd annual report card conducted by Dogwood Alliance and Forest Ethics focuses both on the companies who continue to make progress toward sustainable paper production—and those who don't.

New center for studying temperate rainforests announced in Alaska

Sears catalogue continues to harm boreal forest and caribou

2009-08-17T17:09:00Z

Sears Holding Company, most known for their ubiquitous catalogues, continues to stall on releasing a more environmental paper policy, according to the nonprofit environmental organization ForestEthics. Sears’ long delay to implement a more forest-friendly policy is adding pressure to already threatened caribou populations and deforesting forests in Canada, where the company sources much of its paper.

Boreal forests in wealthy countries being rapidly destroyed

2009-08-12T20:09:00Z

Boreal forests in some of the world's wealthiest countries are being rapidly destroyed by human activities — including mining, logging, and purposely-set fires — report researchers writing in Trends in Ecology and Evolution.

Caribou and reindeer population plunges 60 percent in three decades

2009-06-14T23:07:00Z

The first ever comprehensive survey of caribou worldwide (known as reindeer in Europe) has found that the species has suffered a staggering decline. Researchers from the University of Alberta discovered that the caribou population has fallen 60 percent in half as many years. The study published in Global Change Biology points to global warming and industrial development as the reasons behind the decline.

Reindeer, a symbol of the holidays, is under increasing threat

2008-12-26T18:43:00Z

Reindeer are beloved in the holiday season for the mystical role they play in guiding Santa from the North Pole to the world’s chimneys. However, according to a new book, reindeer, more commonly referred to as caribou, face increasing pressures from a variety of sources. The new book entitled, Caribou and the North: A Shared Future, draws an intimate portrait of the only deer species where both male and females sport horns, while outlining the dangers which may lead these unique animal to become globally endangered.

Drought hurts carbon sinks in North America

2007-11-26T14:30:39Z

A new system for tracking carbon uptake in North America, shows that deciduous forests along the East Coast (32 percent) and the boreal coniferous forests (22 percent) of northern Canada absorbed the bulk of carbon dioxide emissions between 2000 and 2005, but suggests that climate change may increasingly affect carbon sinks, according to research published in the journal Proceedings of the National Academy of Science.

Threatened Amur tiger shows signs of recovery

2007-10-31T14:30:39Z

In a world where many animals are under siege, the Amur tiger -- popularly known in the West as the Siberian tiger -- offers an encouraging message: the population of the huge cat is showing signs of recovery.

2007-10-31T14:30:39Z

Forest fires in the boreal forests of Canada are an important source of greenhouse gas emissions reports a new study published in the journal Nature.

Canada's boreal forest must be saved

2007-05-14T14:30:39Z

At a conference Monday, 1500 prominent scientists called for protection of Canada's boreal forest, one of the largest intact forest and wetland ecosystems remaining on the planet.

Less than 35 Amur leopard remain in the wild

2007-04-19T14:30:39Z

A new census shows the world's most endangered cat, the Amur or Far Eastern leopard (Panthera pardus orientalis), is on the brink of extinction with a wild population estimated at 25-34 individuals. "The recent census confirmed once again that the Amur leopard survives on very shaky ground," said Pavel Fomenko, biodiversity conservation program coordinator at the Far-Eastern branch of WWF in Russia.

Could global deforestation fight climate change?

2007-04-09T14:30:39Z

While many climate change mitigation schemes rely on reforestation schemes to sequester carbon dioxide from the atmosphere, those located in temperate regions may actually be warming the planet, worsening global change, reports a new study published in the April 9-13 online edition of the Proceedings of the National Academy of Sciences. Surprisingly, the research suggests that global-scale deforestation would produce a net cooling effect, but that forest preservation efforts and reforestation in the tropics is more effective in cooling the planet.

Global warming causing disappearance of tundra in Canada

Tundra in northern Canada is being replaced at a rapid rate by boreal forests according to a new study published in the Journal of Ecology. Researchers say global warming is to blame.

Global warming could cause Canadian forests to absorb more carbon

Canada pledges $30 million for Great Bear Rainforest

2007-01-22T14:30:39Z

Canada announced a $30 million plan to protect the Great Bear Rainforest, a 16-million-acre temperate rainforest on British Columbia's Pacific coast. The forest is the largest intact temperate rainforest left on Earth and is home to the 290-foot (90 meter) tall Sitka spruce, black bears, grizzlies and eagles.

Forest fires may cool climate

2006-11-17T03:59:39Z

Boreal forest fires may actually cool climate according to research published in tomorrow's issue of the journal Science. Researchers at the Univerisity of California, Irvine (UCI), found that cooling may occur in regions where burned trees -- and reduced canopy cover -- exposes more snow, which reflects the sun's rays back into space. This effect may outweight the climate warming impact of the grenhouse gases released by forest burning.

Boreal forests worth $250 billion per year worldwide

2006-09-25T06:29:39Z

Boreal forests provide services worth $250 billion per year globally according to estimates by Canadian researchers. Mark Anielski, an Edmonton economist, says that environmental services from the boreal -- including carbon capture and storage, water filtration and waste treatment, biodiversity maintenance, and pest control -- are worth about $160 per hectare, or $93 billion per year in Canada alone.
