Greater Alpine Fire Safe Council Protecting the Alpine community from wildfire and preserving Alpine’s natural and manmade resources through education, land stewardship and fuels management A Few Questions about Wildfires How are wildfires different now than in the past? Are there better ways to protect people and the environment?

Greater Alpine Fire Safe Council Protecting the Alpine community from wildfire and preserving Alpine’s natural and manmade resources through education, land stewardship and fuels management Richard Dana observed: - that in the summer of 1834 a wildfire burnt the town of Santa Barbara to the ground - that severe storms frequently brought high southerly winds and rain to California - by 1859 wildfires were still common but severe winter storms were becoming much less frequent

Greater Alpine Fire Safe Council Protecting the Alpine community from wildfire and preserving Alpine’s natural and manmade resources through education, land stewardship and fuels management The Great Fire of 1910 - the “Big Blow Up” 3 million acres burnt in Washington, Idaho and Montana The largest wildfire in American history - still USFS adopted the doctrine of fire suppression - “the asbestos forest” Unintended consequences: - accumulation of fuels - larger, longer burning wildfires with greater potential for devastation and loss of life.

Greater Alpine Fire Safe Council Protecting the Alpine community from wildfire and preserving Alpine’s natural and manmade resources through education, land stewardship and fuels management A Better Way to Protect People and Environment Return to the Indian practice of using controlled burns as an essential aspect of land management, rejuvenating the landscape in a cyclical manner, and preventing a massive build-up of highly combustible fuels. Where prescribed burns are impractical, reduce fuels by mechanical treatment (“mastication”) The result: - a healthy, frequently burned landscape where new fires move into old fires and put themselves out - a return to the healthy ecological environment that we had before the Big Blow Up Source: Professors Varmer and Stuart, Forestry & Wildland Resources Department, Humboldt State University
