Prescribed Burn Planned for Mid-June
Contact: Denise Louie, (831)389-4486 ext 222
Fire Management staff at Pinnacles National Monument plan to burn 160 acres along the newly acquired bottomlands, and previously burned Entrance Meadow, the second or third week of June if weather conditions allow. Appropriate wind, temperature, relative humidity, and atmospheric pressure will ensure safe and effective prescribed fire operations with good smoke dispersion. The area to be burned is along Highway 146 inside of the park’s east boundary.
The lands recently added to the east side of Pinnacles National Monument include a large infestation of non-native yellow star-thistle. About 12 million acres in California are invaded with this aggressive weed. Three consecutive years of burning, in combination with other integrated plant management techniques, can effectively control yellow star-thistle. Prescribed fire can treat large areas quickly. Burning at the right time of year will greatly reduce the number of seeds that the plants will be able to produce. Fire also recycles nutrients back into the soil, and burns off dead mulch which stimulates the growth of native plants such as lupine, California poppies and perennial grasses. Prescribed burning is just one of the weed control techniques described in the "Integrated Tools to Address Degraded Lands Environmental Assessment" which will be released early this summer.
Safety is the foremost objective in all fire management activities. Prescribed fire is only conducted when the windspeed is low and the air is not too dry. Weather readings will be taken every hour or more during the burn. If an unforcasted weather event creates unfavorable conditions, the burn will be shut down. Extra firefighters and engines will also be on hand as an added precaution.
Burning requires approval from the air quality district to prevent any major smoke impacts on the airshed. Smoke particles may settle with cool air at night and create a trace of haze the morning after burning. If this happens, it will lift as the day warms.

Did You Know?
The yellow star thistle is one of many invasive (non-native) plants threatening the ecosystems of Pinnacles. Many seeds are accidentally transported into the park on shoes and gear; you can do your part to prevent the spread of these pests by cleaning shoes, socks, and gear before visiting the park.
