Prescribed burns around Lake Tahoe set to resume

SOUTH LAKE TAHOE, Calif. – Weather and conditions permitting, California State Parks and the U.S. Forest Service will continue the fall prescribed fire program with operations in D.L. Bliss State Park on the West Shore tomorrow, October 23, 2018, and in Baldwin Meadow on the south end of Lake Tahoe on Wednesday, October 24. Smoke will likely be present. Both of these operations will involve understory burning, which is explained below. A map with project locations and details is available for viewing at http://www.tahoefft.org.

A) D.L. Bliss State Park - Along Lester Beach Road, between Group Camp and Beach Camp. Burning of 65 acres by California State starting 10/23. Duration of Ignition and Smoke Production: 1 week. Estimated Direction of Smoke Travel: Northeast. Communities or Smoke Sensitive Areas: Rubicon Bay, Hwy 89.

B) Burton Creek State Park - North of Rocky Ridge, West of North Tahoe High School. Burning of 19 acres by California State Parks starting 10/30. Duration of Ignition and Smoke Production: 1 week. Estimated Direction of Smoke Travel: Northeast. Communities or Smoke Sensitive Areas: Tahoe City, Highlands, Lake Forest, Hwy 28.

C) Sugar Pine Point State Park - Along lakeside of Hwy 89, north of General Creek. Burning of 54 acres by California State Parks starting 10/23. Duration of Ignition and Smoke Production: 1 week. Estimated Direction of Smoke Travel: Northeast
Communities or Smoke Sensitive Areas: Tahoma, Hwy 89.

D) El Dorado County RX Piles Twin Peaks. Burning of 5 acres by USFS Lake Tahoe Basin Management Unit. Continuation of 10/17 fires. Duration of Ignition and Smoke Production: 2 days. Estimated Direction of Smoke Travel: Northeast. Communities or Smoke Sensitive Areas: Smoke may be visible throughout the Tahoe Basin and surrounding communities.

E) Baldwin Meadow. Burning of 80 acres by USFS Lake Tahoe Basin Management Unit starting 10/24. Duration of Ignition and Smoke Production: 2 days. Estimated Direction of Smoke Travel: Southwest. Communities or Smoke Sensitive Areas: Smoke may be visible throughout the Tahoe Basin and surrounding communities.

Prescribed fire operations are conducted whenever conditions allow to reduce excess vegetation that can feed unwanted wildland fires. Planned fires now reduce the threat of unplanned fires later, which helps provide increased community protection. Fire is a natural process in the Sierra Nevada and helps keep our forests healthy by minimizing the spread of insects and disease, recycling nutrients back into the soil and promoting improved habitat for diverse vegetation and wildlife.

Prescribed fire managers use different methods to reintroduce fire back into our forests that include pile burning and understory burning. Pile burning is intended to remove excess fuels (branches, limbs and stumps) that can feed unwanted wildfires and involves burning slash piles that are constructed by hand and mechanical equipment. Understory burning is low intensity prescribed fire that takes place on the ground (the understory) rather than pile burning. Understory burning uses a controlled application of fire to remove excess vegetation under specific environmental conditions that allow fire to be confined to a predetermined area. Understory burning produces fire behavior and fire characteristics required to attain planned fire and resource management objectives.

Fall and winter bring cooler temperatures and precipitation, which are ideal for conducting prescribed fire operations. Each operation follows a specialized burn plan, which considers temperature, humidity, wind, moisture of the vegetation, and conditions for the dispersal of smoke. This information is used to decide when and where to burn.

Smoke from prescribed fire operations is normal and may continue for several days after an ignition depending on the project size and environmental conditions. Prescribed fire smoke is generally less intense and of much shorter duration than smoke produced by unwanted wildland fires.

Agencies coordinate closely with local county and state air pollution control districts and monitor weather conditions carefully prior to prescribed fire ignitions. They wait for favorable conditions that will carry smoke up and disperse it away from smoke sensitive areas. Crews also conduct test burns before igniting a larger area, to verify how effectively materials are consumed and how smoke will travel.

Before prescribed fire operations are conducted, agencies post road signs around areas affected by prescribed fire, send email notifications and update the local fire information line maintained by the Lake Tahoe Basin Management Unit at 530-543-2816. The Tahoe Fire and Fuels Team gives as much advance notice as possible before burning, but some operations may be conducted on short notice due to the small window of opportunity for conducting these operations.
