Cut a Tree to Fight Global Warming
Thursday, April 3rd, 2008 By Marc Kilmer
Coming from a logging family, I was heartened to see an editorial in Investor’s Business Daily that pointed out the environmental benefits of logging. Having grown up around the timber harvesting industry, I know that many of the environmental harms that are blamed on logging are overblown.
But this author says that a way to combat climate change is to cut more trees:
In the green scheme of things, trees are a good thing and deforestation is bad. We must plant as many trees as we can to suck up all that CO2, the pollutant that sustains all plant and therefore all animal life on earth. Old-growth forests must be protected from those nasty loggers.
Trouble is, according to Thomas Bonnicksen, professor emeritus of forest science at Texas A&M University, forests left in “pristine” condition have too many trees and too many dead ones, both of which provide fuel for the devastating forest fires that ravaged California last year.
Bonnicksen is also a visiting scholar at the California Forest Foundation and has authored a study available at its Web site (calforestfoundation.org). It shows that four large California wildfires produced 38 million tons of greenhouse gases through fire and subsequent decay of dead trees — 10 million from the fires themselves and 28 million from the post-fire decay. This is equivalent to the emissions from 7 million cars for an entire year.
Bonnicksen says the four fires studied involved forests averaging 350 trees per acre where 50 an acre is considered normal. Some California forests, he says, have more than 1,000 trees per acre, with young trees growing under big trees, serving as “ladder fuel” and dead trees and woody debris on the ground.
He advocates “thinning” the forests so they’re less like time bombs waiting to explode. “Harvested trees can be turned into long-lasting wood products that store carbon,” he notes, adding that it’s important to remove trees destroyed by fires and insects “so that they don’t decay and send more carbon dioxide into the atmosphere.”
