WEEDS: Firebrand Defense for the “Typical Catastrophe”
The ideas underlying the WEEDS concept, the proposition that firebrands are responsible for a preponderance of home ignitions, and other concepts put forward in this article come from a number of sources. For those interested in further research, here they are.
Statistics from the National Interagency Fire Council for structure losses in the United States due to wildland fire: 1999 - 817 structures, 2000: 861 structures, 2001 – 731 structures, 2002 - 2381 structures (835 homes)
Self-Organized Critical Phenonmena:
A great explanation of self-organized critical phenomena is given in a book by the late Per Bak, one of the original founders of this field of research:
Bak, Per - How Nature Works: the science of self-organized criticality; Copernicus; 1996
Experimental verification that this theory is applicable to wildland fire was most recently published in the following:
Malamud, B. D., G. Morein, and D. L. Turcotte (1998), Forest fires: An example of self-organized critical behavior, Science, 281, 1840- 1842
Firebrands and Structure Ignition:
Several forensic studies conducted by Australian fire experts revealed that firebrands are the primary cause of structure ignition during wildland fire. The most recent of these was based upon satellite measurements and was published in 2004.

In the United States, USFS Scientist Jack Cohen has raised the firebrand threat issue in a number of his publications and videos. A list of these (http://www.firelab.org/fbp/fbresearch/wui/pubs.htm) can be found at the Wildland-Urban Interface Research Project site of the Missoula Fire lab.
The Australian Way:
Some Australian fire authorities encourage people to stay with their structures and protect them, as described in last year's Wildfire article by Assistant Commissioner Keith Harrap of the New South Wales fire protection agency:
Asst. Commissioner Harrap, Keith; NSW Rural Fire Service; Shelter Shock; Wildfire; Jan/Feb 2004; p. 18
A self-help book by a woman who has devoted most of her life to wildland fire safety describes how to do this:

The Ramona Municipal Water District Hearings:
The testimony of 50 citizens affected by the Cedar fire was heard by the political body responsible for fire protection in Ramona, California. The audio tapes have been transcribed, and are available on the website of the Mussey Grade Road Alliance, a local activist group.
Ramona Municipal Water District Cedar Fire Hearings, January 2004; http://www.musseygraderoad.org/CedarFire/CedarIndex.htm; also available in original audio format from the Ramona Municipal Water District, 105 Earlham Rd., P.O. Box 1829, Ramona, CA 92065
