Forest fires and lightning

Here are some quick facts regarding forest fires from Natural Resources Canada:

Forest fires started by lightning:  

  • Represent 45 per cent of all fires;
  • Represent 81 per cent of the total area burned; and
  • Occur in remote locations and often in multiple clusters.

Forest fire occurrence, and area burned are highly variable:  

  • The area burned by forest fires ranges from 0.7 million to 7.6 million hectares/year;
  • The average area burned is 2.3 million hectares/year;
  • The average fire occurrence is 8000 fires a year ; and
  • The average fire suppression costs are $500 million to $1 billion annually.

Other studies have attributed lightning-related damage and disruption costs to the Canadian economy to be between $600 million and $1 billion each year (Mills et al. 2009).
