This is a map of the National Forests in California. These forests comprise about half of the forestland in California.
The Forest Service graphic below shows the results of the 2000-2009 fire season in California. About 1% of California’s fires chalk up 90% of the total acreage burned. Half a million acres that had the potential to provide wood instead produced smoke filled with carbon dioxide and water vapor.
According to the United Nations, deforestation accounts for nearly one-quarter of human-caused greenhouse gases. Half a million acres were converted by fire and maybe one-tenth of that has been replanted.

Thanks! This is probably the most comprehensive info I have found on this subject on the net. Would you think about hosting guest articles from others?
No, I don’t think allowing spammers to guest post would be all that helpful. Thanks for asking.
