Wildland fires destroy hundreds of homes and acres of land
every year across the country. Fire-safe landscaping is an effective tool
that creates an area of defensible space between your home and flammable
vegetation that protects against devastating fires.
The United States Fire Administration (USFA) encourages
you to keep fire safety at the forefront by learning how to landscape and
maintain your property to minimize possible fire damage and slow fires if
they start. Remember, fire safety is your personal responsibility... Fire
Stops With You!
Defensible Space Works
During the 1993 raging Malibu fires, a number of homes
were saved as a result of the owners careful pruning and landscaping
techniques that protected their homes. In a fire situation, the dead trees
and shrubs surrounding your home act as fuel for fire. Removing flammable
vegetation reduces the threat of fire. Follow these basic rules to create
defensible space that works.
Remove all dead plants, trees and shrubs from the site.
Reduce excess leaves, plant parts and low-hanging
branches.
Replace dense flammable plants with fire-resistant
plants.
The choice of plants, spacing and maintenance are
crucial elements in any defensible space landscaping plan.
Tips for a Fire-safe Landscape
Create a defensible space perimeter by thinning trees
and brush within 30 feet around your home.
Beyond 30 feet, remove dead wood, debris and low tree
branches.
Eliminate small trees and plants growing under trees.
They allow ground fires to jump into tree crowns.
Space trees 30 feet apart and prune to a height of 8 to
10 feet.
Place shrubs at least 20 feet from any structures and
prune regularly.
Plant the most drought-tolerant vegetation within three
feet of your home and adjacent to structures to prevent ignition.
Provide at least a 10 to 15 separation between islands
of shrubs and plant groups to effectively break up continuity of
vegetation.
Landscape your property with fire-resistant plants and vegetation to
prevent fire from spreading quickly.
Choose Fire Resistant Materials
Check your local nursery or county extension service for
advice on fire resistant plants that are suited for your environment.
Create fire-safe zones with stone walls, patios,
swimming pools, decks and roadways.
Use rock, mulch, flower beds and gardens as ground cover
for bare spaces and as effective firebreaks.
There are no fire-proof plants. Select high moisture
plants that grow close to the ground and have a low sap or resin content.
Choose plant species that resist ignition such as
rockrose, iceplant and aloe.
Fire-resistant shrubs include hedging roses, bush
honeysuckles, currant, cotoneaster, sumac and shrub apples.
Plant hardwood, maple, poplar and cherry trees that are
less flammable than pine, fir and other conifers.
Maintain Your Home and Surrounding Property
Maintain a well-pruned and watered landscape to serve as
a green belt and protection against fire.
Keep plants green during the dry season and use
supplemental irrigation, if necessary.
Trim grass on a regular basis up to 100 feet surrounding
your home.
Store flammable materials, liquids and solvents in metal
containers outside the home at least 30 feet away from structures and
wooden fences.
No matter where you live, always install smoke alarms on
every level of your home. Test them monthly and change the batteries at
least once a year. Consider installing the new long-life smoke alarms.
Protect the Outside of Your Home
Stack firewood outdoors at least 30 feet away from your
home.
Keep the roof clear of leaves, pine needles and other
debris.
Cover the chimney with a mesh screen spark arrester.
Remove branches hanging above the chimney, flues or
vents.
