Trees and wildfire risk

Trees are valuable assets, but unmanaged structure, deadwood, and canopy continuity can increase exposure.

What drives risk

Community fuel continuity: coordinated vegetation breaks reduce parcel-to-parcel spread
Wildfire risk is shared—coordinated vegetation breaks can reduce parcel‑to‑parcel spread.
  • Canopy continuity: close crowns enable crown-to-crown spread
  • Deadwood: increases available fuel and ember capture
  • Low limbs: create ladder fuel pathways
  • Proximity: increases radiant heat and ember exposure

Fire-smart management often emphasizes strategic pruning, thinning, and spacing.

Tree spacing and canopy continuity: good vs bad spacing
Spacing that preserves gaps between crowns helps reduce crown‑to‑crown spread potential.

Fire-smart practices

  • Strategic pruning (avoid topping)
  • Canopy thinning to reduce density
  • Canopy raising to reduce laddering (species-dependent)
  • Deadwood and snag management
  • Manage higher-risk species carefully (eucalyptus, pine, cedar, juniper)
