San Bernardino, Ca

The San Jacinto Ranger District of the San Bernardino National Forest plans to conduct a prescribed fire on Thomas Mountain, starting June 10. See map below for the location.

A prescribed fire in California is a planned fire intentionally set under controlled conditions to achieve objectives that can include reducing the buildup of flammable vegetation to decrease the risk of wildfires.

According to the USDA, “Despite its benefits, prescribed fire does come with some challenges: Impact to air quality. Danger to firefighters. Risk of escaping burn prescription and transitioning to wildfire.”

According to the USDA, “The operation is planned to last from seven to 10 days. The district intends to complete approximately 2,500 acres; the district prescribed burned 2,500 acres on Thomas Mt., in the summer of 2023.”

“Road closures will include Thomas Mountain Road 6S13 to 6S15 (Forest Service roads) and Rouse Ridge Road 5S15 (Forest Service road), which already has a closure. There will also be a closure of Forest Service yellow post sites (camping sites) on Thomas Mountain. The Ramona Trail 3E26 will also be closed. These closures will be implemented for the safety of the public and fire personnel. Personnel will be driving many large vehicles while conducting the burn and patrolling the area.”
