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.
