Lightning causes one third of the 9000 wildfires that occur in Canada. Annually, these lightning-caused fires account for 90% of the area burned and cost Canadians at least 150 million dollars in suppression costs and values destroyed. Unlike the fires caused by human negligence…

The character of most forest ecosystems in the southern U.S. has been shaped by fire. Indians and early settlers burned the woods for many purposes. After a period of trying to exclude fire, foresters recognized its value as an ecological force and its necessity as a management…
