October 15, 2025 - Sonora, California - The Groveland Ranger District on the Stanislaus National Forest is planning to implement prescribed fire operations on the Groveland Ranger District late October 2025, pending all required approvals. We estimate this work to continue through late November of 2025 or as weather conditions allow. We use prescribed fires to help reduce overgrown vegetation to help protect local communities, infrastructure and natural resources from wildfires.

Prescribed fire operations are planned for the following sites on the Groveland Ranger District:

• Cherry North Understory Burn, near Wolfin Meadow off FSRD 2N14 and FSRD 2N59
• North Merced Understory Burn, near Anderson Valley off FSRD 2S02 and FSRD 2S71. 

Fire management officials work with California Air Resources Board and Tuolumne / Mariposa County Air Pollution smoke specialists to plan prescribed burns. Prescribed burns are conducted when weather is most likely to move smoke up and away from our communities. While prescribed fire managers take significant preventive measures, it’s likely that communities may experience some smoke during or immediately after a prescribed burn. 

What does this mean for you?

• During prescribed burns, smoke may settle in low-lying areas overnight and in the early morning hours.
• All residents are encouraged to close doors and windows at night to avoid smoke impacts.
• If available, use a portable air cleaner. Air cleaners work best running with doors and windows closed. You can also create a DIY air cleaner.
• If you have a central air system, use it to filter air. Use high-efficiency filters if possible.
• When driving in smoky areas, drivers should slow down, turn on headlights and turn air to recirculating.
• If you have heart or lung disease, asthma, or other chronic conditions, pay attention to how you feel and if symptoms of heart or lung disease worsen, consider contacting your health care professional.
• Visit When Smoke is in the Air for more smoke preparedness resources.

Weather conditions are evaluated regularly up to hours before a burn begins. If conditions warrant, scheduled prescribed fire activities may be canceled.

Prescribed fires are used to reduce overgrown vegetation to help protect local communities, infrastructure and natural resources from the worst impacts of wildfires.
