Compounded by low rainfall, rising summer temperatures, and decades of fire exclusion, wildland fire poses a threat to homes and forests, natural resources, and our environment. Given time, warm temperatures and low relative humidity, trees, grasses and other plants can easily become fuel for a blaze.

  • 674,000 WA acres burned in 2021

  • $372 Million Wildfire damage in WA, 2021

At-Risk Forest

  • Underbrush acts as tinder for fire

  • Fire can climb branches (called ladder fuels) to the crown of a tree

  • Crown fires can sweep from tree to tree, causing intense firestorms

Fire-Resistant Forest

  • Remove fuels from the ground and vertically from trees

  • Remove smaller trees to save room and resources for larger, more fire resistant ones

  • Increase space between trees

  • Safely and legally use prescribed fires to reduce wildfire fuels

Fire Defense Zones

Create a defensible area to protect your home from fire

  • Immediate Zone- Five feet- Remove flammable material, clean roof and gutters, screen vents

  • Intermediate Zone- 30 feet- Reduce fuels, create firebreaks, spread out trees and shrubs

  • Extended Zone- 100 feet- Remove small trees and ground litter, space trees out

  • In case of fires, have an evacuation plan

Restoring Balance

  • Autumn and winter are the best times to thin and prune

  • Clean up debris and ready fire defense zones in spring

  • Mature ponderosa pine and other fire-adapted trees have think bark to help them survive fire

  • More open forests offer enhanced habitat for wildlife.
