However, many are very susceptible to fire, and may die following exposure to heat from even a mild fire. They are like a one-off insurance policy, and would have to be replaced after an intense fire. The layout of your garden is as important for minimising fire risk as choosing the right plant species. This will have a significant effect on reducing the damage fire can do and will provide sheltered areas in which you can actively fight the fire. If they do catch fire, the fire won't be able to spread far.
Spaced trees are safe trees.
Don't grow flammable shrubs under trees. If they catch fire, the fire could set the tree canopy ablaze. Maintain clear areas, possibly green lawn, bare earth, gravel or succulent ground covers near buildings. Fire increases in intensity 3 - 5 times when it is moving up a slope. Plant trees at a distance from the house so that limbs and branches will not overhang the roof or drop leaves on the roof or in gutters.
