Prescribed Burns

Prescribed Burn Projects

Parks & Open Space and the Sheriff’s Office Wildland Fire Management Program plan to conduct prescribed burns when conditions allow. Smoke and flames may be visible for up to 72 hours. There may be heavy smoke in the air. Please do not call 911 since a controlled burn is not an emergency. The areas will be monitored to ensure fires are completely out.

Agriculture and Irrigation Ditch Burning

Agriculture burning is done to remove vegetation to control weeds and prepare areas for reseeding. Irrigation ditches are burned to remove unwanted vegetation for improved water delivery, nutrient cycling, and planting success.

Burn projects depend on weather conditions, including relative humidity, fuel moisture, and wind. Projects will only proceed when conditions are suitable. Fire managers will monitor all projects until they are called out. There may be heavy smoke in the air. Please do not call 911 since these controlled burns are not emergencies.

Slash Pile Burning

Slash pile burns will be conducted at several locations.

  • Hall Ranch (west of Lyons)
    There are no planned closures of the trails or property during pile burns.
    Crews burned piles on 2/17-18, 1/29, 1/24-25, 1/8-12, and 4/18, and will continue to burn when conditions allow.
  • Overland Property (west of Jamestown)
    Crews will burn when conditions allow.
  • Mud Lake / Sherwood Gulch (north of Nederland) COMPLETED
  • Reynolds Ranch (east of Nederland) COMPLETED

Burns are usually scheduled when there is a winter weather system in the area. Operations will be conducted only when conditions ensure safe fire operations and containment. Pile burns are conducted to reduce the amount of fuel on the ground as a result of thinning operations.

Staffing

Boulder County Parks & Open Space, Boulder County Sheriff’s Office Wildland Fire Management, along with numerous local and federal fire departments, conduct prescribed burns. The project areas are well contained by trails and roads, and fire hoses and fire engines will completely surround the area during the duration of the burns. Firefighting resources will remain on site until the fire is out or controlled by weather conditions.

Benefits of Prescribed Fire

  • Reduces hazardous fuels, protecting human communities from extreme fires.
  • Minimizes the spread of pest insects and disease.
  • Removes unwanted species that threaten species native to an ecosystem.
  • Provides habitat for foraging wildlife.
  • Improves habitat for threatened and endangered species.
  • Recycles nutrients back to the soil.
  • Promotes the growth of trees, wildflowers, and other plants.

Smoke Issues

  • Prescribed fire smoke may affect your health. Learn how to protect your health from wood smoke.
  • During a prescribed burn, smoke is generated and will drift according to wind currents and other atmospheric conditions.
  • Smoke could settle in areas at night when cooler air traps the smoke particles closer to the surface of the ground.
  • Smoke will be visible from Foothills Highway, Lyons, Boulder, Estes Park, Longmont, Fort Collins, Loveland and possibly east to I-25.
  • Children, older adults and people with heart or lung disease are more likely to be effected by smoke.
  • Close windows and stay indoors if you are concerned.

After the Burn

  • Residual smoke may be visible.
  • Firefighting resources will remain on the prescribed burn until the fire is confirmed as being controlled by significant weather conditions or determined to be out.
  • There are also monitoring plots for important data gathering. These plots were studied before the fire, and researchers will return after the fire to document scientific changes.
