For thousands of years, Native Americans in what is now California and across the West treated and nurtured fire like a natural resource through the practice of cultural burning.
Cultural burning views fire as restorative, not destructive.
Native people burn to enhance vegetation, not just remove it. Reducing fuel loads is just one of many benefits fire holds for ecosystems. For millennia, Indigenous people worldwide have applied small fires to the land to renew plants and watersheds for food, wildlife habitat, medicine, basketry and other cultural uses.
As wildfires burn bigger, hotter and more frequently each year, state and local agencies, groups and landowners are increasingly looking to Native people — the original land managers — for guidance on living with fire.

"There’s a difference between cultural burning and just setting fire on the land. We use fire as a tool." – Ron Goode
Historically, wildfires in California tended to burn frequently but at lower temperatures that maintained healthy soil, water and forests. Prescribed fires and cultural burns both serve to mimic those conditions.

An Era of Destructive Wildfires
Wildfires around Cohasset
Of the seven Ridge-Top communities in Butte County,only three have remained unscathed by wildfire over the last twenty years.
Current Conditions
Fire Modeling
The following map shows flame length before and after fuels reduction treatment. Twenty five foot plus flames can become four to eight foot flames after treatment. Simulation does not include wind speed just current fuel loading. Use the slider to compare.
Most of the recent catastrophic fires in the Butte County area have been driven by north wind events. Winds during the 2018 Camp Fire reached speeds in excess of 60 mph, and the 2020 North Complex Fire’s exponential growth was driven by winds gusting to 45 mph. In Cohasset, north winds are not uncommon in the fall and can have maximum wind speeds over 30 mph.
The following maps show fire spread before (left) and after (right) the proposed treatment. Fire spread is measured from time of ignition in a set hourly interval period. Use the slider to compare.
Solutions and Goals
A Plan for Survival
The following slides show the progression of a fire from ignition to a crown fire and gives key solutions to help reduce negative impacts on your property.

Evacuation Route
Cohasset and the surrounding area have one travel route for access; Cohasset Road. In the case of a major wildfire, this evacuation route becomes paramount for the survival of community members.
Our Responsibilities
One of the ideas that has been repeated throughout this document is that YOU are responsible for yourself and your property. Over grown vegetation is a safety hazard to your home and your neighbors. Any vegetation treatment that you do to your property can positively impact your home and your neighbors. When you clear over grown vegetation, you're decreasing the chances that your home can be destroyed by a catastrophic wildfire.
The many suggestions provided throughout this document can help prevent your home from igniting. Fire hardening your home, removing all flammable materials within seven feet, keeping flammable vegetation within 30 feet to a minimum and decreasing ladder fuels on your property is the best way to keep your home, your property and your community safe.
Don't forget you're not alone. There's an abundance of resources available to assist you with keeping your property fire safe:
