These infestations irrupt rapidly a decade later into massive outbreaks cover-ing 460 000 ha of lodgepole pine forests. Wildfire burns over 348 000 ha of British Columbia's forest land in 1982.

These extraordinary events can mean different things to different people: a reduced timber harvest, a lost wilderness reserve, an unsightly recreation area. Many of the feelings generated embrace a sense of loss and the belief that nature is on the rampage. But while these scenarios may appear to conflict with and impair a multitude of forest resource values, these natural disturbances show evolution in action and can actually maint ...
