Modifying the lay of the land for fire resistence

Creating defensible space around woodland homes is a legal requirement and common-sense habit. UC Cooperative Extension has developed extensive information that will help homeowners maximize safety while maintaining the greenery that makes rural living desirable, according to an article in the Redding Record Searchlight.

Defensible space, yes, but UC Cooperative Extension forestry advisor Gary Nakamura told reporter Laura Christman, "It doesn't mean you need to nuke the site and clear it."

Bare dirt would be the ultimate in fire defense, but such a landscape comes up short in appearance, erosion control and wildlife habitat. Besides, Nakamura said, many homes that succumb to wildland fire are ignited by embers that drifted a long way from the fire line.

"It's usually not this wall of wildfire coming to the house. That's people's cartoon vision of what happens," Nakamura was quoted.

The strategy of defensible space is to have an area around the house where embers are less likely to ignite plants or structures. Or, if an ember does start a fire, the fire will smolder or burn slowly so it can be extinguished. Homeowners need to create conditions so that firefighters can "safely get in there and fight the fire," Nakamura advised.

The story noted that UC's Home Landscaping for Fire publication recommends thinning brush and trees 70 feet beyond the "lean and green zone," a 30-foot band around the home. Trees shouldn't have limbs any closer than 10 feet from each other and spacing should be farther on hillsides, where fire picks up speed and intensity.

UC has collected research-based information about protecting homes from fire in a wildfire online media kit. The resource contains links to stories, video and UC Web sites dedicated to helping Californians minimize fire damage and stay safe.
