Lake Tahoe Prescribed Fire Projects

Lake Tahoe Basin Management Unit - LTBMU Prescribed Fire Projects

Prescribed Fire Projects October 1, 2008
South Shore South Lake Tahoe, CA. --On October 1, 2008, Forest Service Fuels Management crews are planning on conducting prescribed fire operations vicinity of North Upper Truckee and Otomites. Approximate acreage is 1 consisting of hand piles. This project is dependent on favorable weather conditions.
Residents and travelers can expect to see smoke from prescribed fire project areas.
This and other prescribed fire projects are designed to reduce wildfire risks to communities and critical resources. Smoke management is part of every prescribed fire burn plan, and efforts will be taken to reduce actual or potential smoke impacts on community areas.

South Lake Tahoe, Calif. Oct. 2, 2008 - The U.S. Forest Service Lake Tahoe Management Unit plans to conduct a prescribed fire underburn to restore forest health on 115 acres of National Forest System lands near Tahoe City. The project, located northeast of Highway 89 near Burton Creek State Park, off Forest Road 16N73 (Fiberboard Freeway), could begin as soon as Friday, October 3, 2008, if weather conditions are favorable for ignition.

Forest service crews would conduct the burn in 30-40 acre units, beginning at the top of the slope and working down. After 24 hours, crews may extinguish the edges of the burn area and any large smokes (smoldering stumps or log clumps). The underburn generally will consist of low-to-moderate intensity fire. Some tree mortality is expected and is actually desirable for ecosystem benefits in some of the units.

Ignitions will only occur on Placer County Air Pollution Control District allowable burn days. The Forest Service will have sufficient fire suppression resources available to staff the burn and a smoke management plan is in place to minimize the impact. However, local residents can expect to see smoke from this project inside communities. Smoke from prescribed underburns will be less severe and more manageable than from unwanted wildland fires.

Underburns are conducted to promote healthier and more sustainable forest conditions by reintroducing fire into the ecosystem. These fires help release nutrients that plants and trees need for growth, cause seeds of some species to sprout and improve wildlife habitat. They also help maintain desirable fuel loading conditions by consuming woody debris and brush on the forest floor. Underburns are only conducted after unnatural densities of small diameter tress as well as dead fuel build ups have been removed. This allows the underburn to mimic the low intensity fires common before settlement of the basin.

The lower elevation regions of the Tahoe Basin were originally highly fire adapted forests. Between 8,000 and 10,000 acres burned annually before settlement began in the 19th century. These low intensity slow-moving fires crept along the forest floor burning away the "duff" material on the surface. Duff is mainly decomposing pine needles, bark chips, cones and small branches.

This operation is part of the larger Lake Tahoe Ecosystem Underburn Project, which calls for conducting prescribed underburning on 400-640 acres per year in stands that have already been treated to reduce dangerous levels of fuels.

How fires get their names

Every year in California thousands of wildfires start throughout the state. In most cases, the dispatch center sending the initial resources to a wildland fire will designate a name for the fire, but the first on scene engine or fire official can also name the incident. Fires are usually named for the area in which they start – a geographical location, local landmark, street, lake, mountain, peak, etc. Quickly naming the fire provides responding fire resources with an additional locater, and allows fire officials to track and prioritize incidents by name. For example during the Southern California Fire Siege of 2003, the largest wildland fire in California history, the Cedar Fire in San Diego County, was named after the Cedar Creek Falls area where it started. The destructive Old Fire, which burned during the same time period in San Bernardino County, was named after the road along which it started - Old Waterman Canyon Road.

CAL FIRE is the largest fire department in California and the second largest fire department in the United States. CDF - CAL FIRE Firefighters answer the call more than 300,000 times a year. CAL FIRE Firefighters make up the fire department for 30 of our 58 counties in California and more than 100 local communities. We serve as the incident command during many of California’s most serious disasters. CAL FIRE Firefighters respond to many various types and forms of calls ranging from structural fires, to auto accidents, to earthquakes, to floods, to the spilling of hazardous materials, to every conceivable disaster; CAL FIRE answer's the calls. CAL FIRE is the largest fire department in California and the second largest fire department in the United States . CAL FIRE firefighters protect 33 million acres of State Responsibility Area (SRA). We have over 4,000 members within CAL FIRE and CAL FIRE is associated with the California Professional Firefighters (CPF) and the International Association of Firefighters (IAFF).
