Fire Resistant Plants

Fire-Resistant plant materials 

for the Inland Empire

All plants will burn under extreme fire weather conditions such as drought.  However plants burn at different intensities and rates of consumption.  Fire-resistive plants burn at a relatively low intensity, slow rates of spread and with short flame lengths.  The following are characteristics of fire-resistive vegetation:

1.  Growth with little or no accumulation of dead vegetation (either on the ground or    standing upright).

2.  Non resinous plants (willow, poplars).

3.  Low volume of total vegetation (for example, a grass area as opposed to a forest or shrub-covered land).

4.  Plants with high level fuel moisture (plants that contain a large amount of water in comparison to their dry weight).

5.  Drought tolerant plants (deeply rooted plants with thick, heavy leaves).

6.  Stands without ladder fuels (plants without small, fine branches and limbs between the ground and the canopy of overtopping shrubs and trees).

7.  Plants requiring little maintenance (slow-growing plants which, when maintained, require little care).

8.  Plants with woody stems and branches that require prolonged heating to ignite.

Plants that ignite readily and burn intensely are fire-prone plants and typically share the following characteristics:

  • are waters-stressed.

  • usually accumulate fine, twiggy, dry or dead material. (cedar bushes)

  • have leaves and wood containing volatile waxes, fats, terpenes, or oils. (junipers)

  • are typically aromatic (crushed leaves have strong odors).

  • have gummy, resinous sap with strong odor.

  • are usually blade-leaf or needle-leaf evergreens.

  • have stiff, leathery, small or fine lacy leaves.

  • may have pubescent (hair covered) leaves.

  • may have loose or papery bark.

  • are plants that flame (not smolder) when preheated and ignited with a match.
