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 control of wildfires in forested areas may not always be a desirable objective since certain benefits can result that are important enough to warrant prescribed burning in some cases. Included in these benefits is the control of harmful insects and plant diseases and of…

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…
