Wildfires
There is an interesting site on wildfires at
http://library.thinkquest.org/C01191...sh/index.shtml According to the historical fires section, before Europeans settled North America, 13 million acres a year burned. Compare that to the 8.4 million acres burned in the 2000 fire season and 6.5 million acres in 2002. -- http://home.teleport.com/~larryc |

There is an interesting site on wildfires at http://library.thinkquest.org/C01191...sh/index.shtml According to the historical fires section, before Europeans settled North America, 13 million acres a year burned. Compare that to the 8.4 million acres burned in the 2000 fire season and 6.5 million acres in 2002. That would include grasslands, sagebrush and prairies, in addition to all the fires that were purposely set by American Indians. Much of those wildfires only burned the flashy fuels and left the forests in place. Of course, there was always that catastrophic component in some of the non-ponderosa pine forests. We've just "helped" it along a bit with high-grading, species conversions and fuel loading. I saw one area just outside the western boundry of Yosemite that has burned 13 times in the last 100 years. Talk about a lightning rod?!?! Larry, forest sculptor |
