Prepare for Wildfires: Create a Defensible Space with Fire Resistant Landscaping

As Texans, we expect summers to be hot and humid and the summer of 2023 has been hotter than normal.  Unfortunately we also know it is not a matter of if we will have a drought but when.       

The National Oceanic and Atmosphere Administration (NOAA) estimates that there have been 18 droughts in Texas since 1980, including the drought that started in 2021.  Since 1895, the most significant drought in Texas’ history was 1950 to 1957, lasting 77 months.   The 2010 to 2014 drought was the second longest, lasting 51 months, and the second worst, in part because 100% of the state was affected for many weeks and 88% during the most intense period.  (NOAA) forecasted that the current drought that Texas has been experiencing since 2021 will continue through 2023 unless the state receives significant, wetting rainfall.  https://www.drought.gov/states/texas#drought overview

Living in the Piney Woods of Texas, a region thickly forested with pines, oak, sweetgum, magnolia, tupelo, elm and ash, means that the potential for wildfires always exists;  during extended periods of drought and excessive heat the risk increases dramatically. The Tri County Fire (also known as the Riley Road Fire) started on September 5, 2011 and lasted 28 days.  It burned 20,000 acres and destroyed 73 homes in Montgomery, Walker and Grimes counties.  It was started by a lightning strike.  During 2011 there were 4,064 fires in Texas that burned 300,279 acres and destroyed 2,139 homes.       

The Keetch-Byram Drought Index (KBDI), twc.tamu.edu/kbdi, is used in determining wildfire potential.  The interactive map shows values by county. he current fire danger can be viewed at https://tfsweb.tamu.edu/DailyFireDanger/

PREVENT WILDFIREs

While preventing wildfires is sometimes out of the average person’s control, such as when it is caused by arson, lightning or a sparking transformer, there are steps that individuals can take to minimize the possibility of causing a wildfire.  These include:

PROTECT YOUR HOME FROM WILDFIREs

While there are no guarantees, there are steps that individuals can take to increase the probability that their homes will survive a wildfire.  The Texas A&M Forest Service Firewise program outlines how to prepare the area around a home to reduce the ability for a wildfire to reach the home. Texas A&M Forest service says “The first 30 feet from your home in all directions is called your defensible space.  Maintaining defensible space around your home is key to improving your home’s chance of surviving a wildfire”.   Firewise divides the area around the home into 3 zones.

Immediate Zone:  0 – 5 feet from the house – non-combustible area

Intermediate Zone:  5 – 30 feet from the house – keep fire from climbing to crowns of trees

Trees

Extended Zone: 30 – 100 feet from the house – interrupt fire’s path; keep flames smaller and on the ground

Trees

Below are a few examples of fire-resistant plants that can be used; there are many more.  Check online and with your local nursery.

First 10 feet from home – low growing and moist

10 feet to 30 feet from home – taller plants

30 feet and beyond from home – shrubs

HIGH FIRE RISK PLANTS TO AVOID

Below is a list of some high fire risk plants that should not be used; there are many.  Check online and with your local nursery about other high risk plants.
