Maintaining proper defensible space around your home is key to fire safety in Northern California. CAL FIRE defines three zones to guide vegetation and tree management:
-
Zone 0: 0–5 ft from structures
Keep this area completely clear of flammable vegetation. Remove all brush, mulch, and low-hanging branches to minimize fire risk. -
Zone 1: 5–30 ft from structures
Maintain low-growing, fire-resistant plants. Prune trees so branches are at least 10 feet apart from other trees and buildings. Remove dead or dying trees and debris. -
Zone 2: 30–100 ft from structures
Thin out dense brush, small trees, and dead material to reduce fire spread. Space remaining trees to lower the risk of crown fires.
Following these CAL FIRE specifications helps protect your property while keeping your trees healthy and manageable.
