Provinces, First Nations save boreal forest

Canada sets aside its boreal forest as giant carbon vault
By banning logging, mining and oil drilling in an area twice the size of California, Canada is ensuring its boreal forests continue to soak up carbon

The Guardian: In the far north latitudes, buried within a seemingly endless expanse of evergreen forests, the authorities of Canada are building up one of the world's best natural defences against global warming. In a series of initiatives, Canadian provincial governments and aboriginal leaders have set aside vast tracts of coniferous woods, wetlands, and peat. The conservation drive bans logging, mining and oil drilling on some 250m acres...

In the latest addition to the carbon storehouse, the provincial premier of Manitoba, Gary Doer, announced a $10m Canadian fund to protect a 10.8m acre expanse of boreal or evergreen forest. It was one of Doer's last acts as premier; he took over as Canada's ambassador to Washington this month.

The $10m will go towards efforts by indigenous leaders to designate boreal forest lands in eastern Manitoba as a Unesco world heritage site. The Pimachiowin Aki world heritage project, which straddles the Manitoba-Ontario border, extends efforts by Canadian provincial leaders to protect the wide swaths of pristine forests in the north. It also ensures the survival of one of the best natural defences against global warming after the world's oceans, environmentalists say.

A report by the International Boreal Conservation Campaign said the forests, with their rich mix of trees, wetlands, peat and tundra, were a far bigger carbon store than scientists had realised, soaking up 22% of the total carbon stores on the Earth's land surface...

Canada's cold temperatures slow decomposition, allowing the build-up of organic soil and peat. The forest floors beneath its evergreens hold twice as much carbon per acre as tropical forests, such as the Amazon...

Canada's 1.3bn acres of boreal forest store the equivalent of 27 years' worth of current global greenhouse gas emissions, a Greenpeace study found. The destruction of those forests, scientists warn, would be like setting off a massive 'carbon bomb' because of the sudden release of emissions.
