For US Forests, Megafire Recovery To Be Slow Or None

For US Forests, Megafire Recovery To Be Slow Or None say experts, reports Mark Grossi at the Fresno Bee. The huge Yosemite Rim fire in California is a good example. It consumed over 300 square miles of forest, and extinguishing it is costing more than $50 million. Experts say the ecosystem damage is huge. In a terrifying whoosh, the Rim fire changed the forest for at least a generation and maybe a lot longer. As the climate changes and more fire takes place, there is a chance big fire-resistant trees might not recover. Fields of flammable shrubs might be all that is left in some places, fire ecologists say. Further, much of the Sierra’s 25 million acres is overgrown and primed for these kinds of large, hot wildfires. Some day, many parts of the Sierra may resemble Southern California mountains where evergreen shrublands dominate the landscape. Such flammable chaparral can fuel future climate-driven fires.   US forest mismanagement and global warming have created megafires that will make recovery slow or impossible for forests throughout the west.

 

Join the swelling numbers of voters TELLING Congress they’ll vote for Clean Energy candidates here: http://signon.org/sign/we-are-the-clean-99?source=c.em.cp&r_by=487176 . This is an ongoing campaign (the next Congressional election is in 2 years!) so please, spread the word. It’s our way of telling Congress that a strong clean energy voting bloc is out there. This is how YOU can make a difference.
