Minimum Distance Away from Trees for Ground Burns?

April 5, 2026

Quick Answer

The minimum distance away from trees for ground burns, also known as a fire star lay, is 10 to 20 feet. This distance allows for the fire to burn in a controlled manner, without posing a significant risk to nearby trees. It also helps to prevent embers from igniting nearby fuels.

Preparing the Fire Star Lay

When creating a fire star lay, it’s essential to clear a 10 to 20-foot radius of flammable materials, including leaves, grass, and small twigs. This will help contain the fire and prevent it from spreading to nearby trees. You can use a firebreak or a designated fire ring to achieve this.

Fire Behavior and Safety Considerations

When a fire is burning in a fire star lay, it’s crucial to monitor its behavior closely. Embers can ignite nearby fuels, including tree bark, leaves, and other combustible materials. To mitigate this risk, keep a firewatcher on duty at all times, and have a bucket or other fire-suppression tool nearby. A fire star lay can also be used to create a controlled burn, but this requires careful planning and execution to ensure safety.

Techniques for Creating a Fire Star Lay

To create a fire star lay, start by clearing a 10 to 20-foot radius of flammable materials. Next, create a firebreak or a designated fire ring using rocks, dirt, or other non-combustible materials. Once the fire is lit, monitor its behavior closely and have a fire-suppression tool nearby. Keep the fire small and controlled, and never leave it unattended.
