Shrubs, hedges, and ladder fuels

Shrubs often ignite early and can form vertical pathways that carry fire upward.

Ladder fuels: good vs bad shrubs and canopy clearance
Dense shrubs and low limbs can create a vertical fire pathway into the canopy.

Common high-risk patterns

  • Dense shrubs adjacent to structures
  • Continuous hedges without breaks
  • Shrubs beneath trees where fire can ladder upward
  • Woody plantings that accumulate dead material

Spacing and maintenance patterns often matter more than whether a plant looks “green.”

What to aim for

  • Break continuous shrub beds into smaller groups
  • Maintain separation from low branches and canopies
  • Remove dead material regularly during peak season
  • Use hard breaks where needed (paths, cleared edges)
