I find some hope for the future of our planet in the emergence of millions of unconnected environmental and social movements. The leaderless Anarchy of this mass phenomenon and its macro scale means that its cells will not be centrally controlled or turned aside by profit motives. It seems to be a genuine grass roots response to the global threat which our planet faces. —Paul Hawken «

Study Finds Not Logging Some Northwest Forests Could Offset Climate Change

One thing you can do:
Help to preserve forests

By Jillian Mock

When we make a mess in the kitchen, many of us reach for paper towels without sparing a thought for where those crisp white sheets originated.

If you’re in North America, some of the fiber in your paper towels (and other tissue products like toilet paper) probably started off as a tree in the boreal forest of northern Canada, one of the last big, intact forests in the world.

Boreal forests stretch across Canada, Alaska, Siberia and Northern Europe, and, together, they form a giant reservoir that stores carbon dioxide. That’s important, because that carbon would otherwise be released into the atmosphere and contribute to global warming. Collectively, boreal forests lock away about 703 gigatons of carbon in woody fibers and soil. Tropical forests, by comparison, store about 375 gigatons of carbon.

These are tough times for forests, though. Because of climate change, they’re highly susceptible to wildfires, like the ones in Australia, and pest infestations. So, anything we can do to keep them intact is good.

Trevor Hesselink, director of policy and research at the Wildlands League, a Canadian conservation organization, said it’s important to weigh the value of paper products against the value of intact forests. “If you are thinking through a carbon lens, those single-use products are very short-lived,” he said.

Canada is generally seen as being good at forest management. In logged areas of the boreal forest, trees are replanted and allowed to regenerate, and the country boasts a very low official deforestation rate of just 0.02 percent (though that has been disputed by some environmental groups).

The bad news is, even if actual deforestation is low, planting a young tree to replace a mature one is not the one-for-one carbon scenario many people imagine, Mr. Hesselink said.

For a long time, scientists believed older trees stopped absorbing carbon as they aged. But recently, researchers have that found older trees continue absorbing carbon dioxide for decades or even centuries longer than originally thought, said William Moomaw, a physical chemist and lead author on five Intergovernmental Panel on Climate Change reports.

Leaving existing forests to grow will be more effective at mitigating climate change over the next 80 years than reforestation or planting new forests, Dr. Moomaw and his colleagues have said. A tree planted this year won’t make much of a difference in terms of carbon sequestration over the next decade, a period many scientists say is critical for climate action. “They just don’t absorb enough carbon dioxide,” Dr. Moomaw said. “They aren’t big enough.”

Furthermore, boreal forests support a diverse array of plant and animal species. They’re also central to life for hundreds of indigenous groups.

There is some debate over the degree to which pulp and paper products, like the disposable towels in your kitchen, drive logging activity in the boreal forest.

Tony Lemprière, senior manager of climate change policy in the Canadian Forest Service, pointed out that industry can use waste from timber production to make paper products. But the Natural Resources Defense Council estimates that 44 percent of the pulp produced in Ontario comes from whole trees rather than byproduct.

Regardless, it’s easy to reduce the amount of single-use paper products you buy.

Reusable cloth towels are a great alternative, said Shelley Vinyard, who heads the boreal forest program at the Natural Resources Defense Council. For those moments when you really do need a paper towel, she recommends one made of recycled content. The council’s consumer guide has recommendations for paper towels, toilet paper and facial tissues.

We really need to be thinking about forests in a different way at this “critical junction,” Mr. Hesselink said. Instead of soaking up spilled milk, those trees can help us tackle a much larger mess.

A new study finds some Northwest forests have a lot of potential to capture carbon and offset climate change. That is, if they’re preserved and not logged.

Researchers at Oregon State University and the University of California-Berkeley looked at which forests in the Western United States should be prioritized for preservation under climate change scenarios.

They analyzed which forests have the most potential to sequester carbon, are least vulnerable to drought and fire, and also provide valuable habitat for endangered species.

Many of the forests that hit that trifecta are along the Oregon and Washington coast and in the Cascade and Olympic mountains.

“The amount of carbon per acre that they take up is as high or higher than tropical forests,” said Beverly Law, a professor of global change biology and terrestrial system sciences at Oregon State University and co-author of the study. “Those are really what I call the land sinks that are so critical to try and make sure we preserve them.”

The study, published Dec. 4 in the journal “Ecological Applications,” finds not logging high-value forests would be equivalent to halting six to eight years of the region’s fossil fuel emissions.

“To some, it might seem like a sacrifice,” Law said. “To others, it might be ‘Thank goodness, I can do something to help us get out of this problem we’ve gotten ourselves into.’ It is serious.”

Burning fossil fuels like coal, gasoline and natural gas produce carbon that gets trapped in the atmosphere. This is resulting in rising average temperatures and many dire consequences: melting glaciers, extended droughts and more severe wildfires, among them.

The study found the high-value forests makes up about 10% of the forestland in the West, including some areas in northern Idaho and Montana.

The Oregon Forest Industries Council did not respond to a request for comment. The industry group has criticized Law’s previous research findings that concluded timber harvest is the leading source of carbon emissions in Oregon.
