RESOURCES - California and Wildfires 
California has a long history of wildfires. These links will provide you with information on:

  • The costliest California wildland fires

  • Leading property/casualty insurance companies by market share in California.

Fire plays an important role in the life of a forest, clearing away dead wood and undergrowth to make way for younger trees. But for much of the last century, fire-suppression policies have sought to extinguish wildfires as quickly as possible to preserve timber and, increasingly, real estate. These policies have led to the accumulation of brush and other vegetation that is easily ignited and serves as fuel for wildfires. Most of the large fires with significant property damage have occurred in California, where some of the fastest developing counties are in forest areas.
