Studies and analysis of previous wildfires have shown that defensible space, along with home hardening (e.g., non-flammable roof and vent screen modification) are more times likely to survive a wildfire than those without a defensible space.
Here are two local examples of defensible space making a difference in our area:
Jones Fire – Homes in the Tasha Rd. area that had done defensible space work were saved.
49er fire – A home on Highgrader Rd. in Rough and Ready survived both the 49er fire and the Lobo fire. https://www.theunion.com/news/local-news/surviving-the-fires-one-familys-story-of-how-they-avoided-disaster-twice/
