Eastern Redcedar as a Hazardous Fuel

Why is Eastern Redcedar a Hazardous Fuel?

  • Eastern redcedar’s (ERC) fine foliage contains volatile oils that make it ignite and burn easily.
  • ERC’s growth form brings the flammable foliage close to the ground, where a grass fire can ignite it.
  • When ERC grows in forests and woodlands, it acts as a ladder fuel to allow fire to climb into the crowns of taller trees.
  • When ERC burns, it showers thousands of burning embers downwind, which increases the chance of spot fires and the overall rate of fire spread.
  • ERC is often planted in farmstead windbreaks or as an accent plant, where it may come in contact with a house, creating a path for fire to spread onto the home.


Eastern redcedar invades native forests and can cause the destruction of fire-tolerant trees if a wildfire moves through the area.


Creating fuel breaks (such as sidewalks or driveways), clearing a 30-foot area around the house, using construction material that is fire resistant or noncombustible, mowing regularly, and similar processes can help protect a home during a wildfire.

Eastern redcedar are a ladder fuel, and can transport a ground fire to the roof of a home.

 Homes built on land invaded by eastern redcedar run a higher risk of burning during a fire. Owners need to acquire the knowledge to protect themselves and their belongings. One way to accomplish this is by allowing a 30- to 60-foot open space between eastern redcedars and the roofline. Prune any eastern redcedar growing close to the home to at least six feet above the ground.

Eastern redcedar is a ladder fuel because of its growth form. A ladder fuel provides a path for a fire to go from grass fuel on the ground up into a tree canopy. If a house (also fuel) is next to the tree, it will burn. Eastern redcedar is a volatile fuel that contains chemical compounds that burn rapidly and at high temperatures. Thus, when eastern redcedar ignites, it is hazardous to homeowners and firefighters alike.
