Fire and Smoke Model Evaluation Experiment (FASMEE): Fishlake National Forest prescribed burn

Media Gallery Posted on: July 08, 2019
The Fire and Smoke Model Evaluation Experiment (FASMEE) is a large-scale interagency effort to identify how fuels, fire behavior, fire energy and meteorology interact to determine the dynamics of smoke plumes, the long-range transport of smoke and local fire effects such as soil heating and vegetative response. FASMEE is designed to collect observations from large prescribed fires by combining Light Detection and Ranging (LiDAR), radar, ground monitoring, aircraft and satellite imagery, and weather and atmospheric measurements.

The Fire and Smoke Model Evaluation Experiment (FASMEE) is a large-scale interagency effort to identify how fuels, fire behavior, fire energy and meteorology interact to determine the dynamics of smoke plumes, the long-range transport of smoke and local fire effects such as soil heating and vegetative response. FASMEE is designed to collect observations from large prescribed fires by combining Light Detection and Ranging (LiDAR), radar, ground monitoring, aircraft and satellite imagery, and weather and atmospheric measurements. Knowing more about how wildland fire operates helps land managers better predict fire behavior, smoke impacts, and the short- to long-term effects of fire. It also promotes increased public and firefighter safety and aids in the allocation of firefighting resources.

Postharvest residue burning under alternative silvicultural practices

Documents and Media Posted on: December 20, 2018
Prescribed burning of logging slash was done in clearcut, overstory removal, and understory cutting units in a Douglas-fir stand on the Lubrecht Experimental Forest near Missoula, Mont. The burning prescriptions and actual burning conditions are described. Data on preharvest, postharvest, and postburn conditions are reported.  Document Type: Other Documents

Effects of prescribed fire on soil nitrogen levels in a cutover Douglas-fir/western larch forest

Documents and Media Posted on: November 30, 2018
The effects of a prescribed broadcast fire on soil nitrogen (N) levels and related soil properties were determined following the clearcutting of a 250-year-old Douglasfir/western larch stand in northwestern Montana. Soil N losses from burning amounted to slightly over 90 Ib/acre (100 kg/ha), all from the surface organic layers. This was 6 percent of the total N originally present in the surface 12 inches (30 cm) of soil.Document Type: Other Documents

Short- and long-term effects of prescribed underburning on nitrogen availability in ponderosa pine stands in Central Oregon

Documents and Media Posted on: October 03, 2018
The effects of prescribed underburning on soil total C pools, total and inorganic N pools, and in situ net N mineralization were examined during a 1-year study in ponderosa pine (Pinus ponderosa Dougl. ex P. & C. Laws.) sites that had been experimentally burned 4 months, 5 years, or 12 years earlier.Document Type: Other Documents

Soil organic matter in a ponderosa pine forest with varying seasons and intervals of prescribed burn

Documents and Media Posted on: October 03, 2018
Prescribed burning is used to reduce fuel loads and return ponderosa pine forests of the Western U.S. to their historical structure and function. The impact of prescribed burning on soil is dependent on fire severity which is largely managed by burning in the fall or the spring; frequency of fire will also regulate long-term fire impacts.Document Type: Other Documents

Associations between forest fire and Mexican spotted owls

Publications Posted on: August 01, 2018
In 1993, the US Fish and Wildlife Service listed the Mexican spotted owl (Strix occidentalis lucida) as threatened, in part because of the rising threat to its habitat from stand-replacing wildfires. In 1997, we surveyed 33 owl sites that, in the previous four years, had burned at various levels ranging from light controlled burns to stand-replacing fires.

Antelope bitterbrush and Scouler's willow response to a shelterwood harvest and prescribed burn in western Montana

Publications Posted on: June 23, 2017
In many western Montana ponderosa pine (Pinus ponderosa) stands, fire suppression and past selective logging of large trees have resulted in conditions favoring succession to dense stands of shade-tolerant, but insect- and disease-prone Douglas-fir (Pseudotsuga menziesii).

Wildland fire: Nature’s fuel treatment

Publications Posted on: December 27, 2016
Every year wildland fires affect much more acreage in the United States compared to controlled burns. Like controlled burns, wildland fire can help promote biological diversity and healthy ecosystems. But despite these facts, wildland fire is not often considered as a fuel treatment in the United States. Scientists working with the U.S.

Postfire mortality of ponderosa pine and Douglas-fir: a review of methods to predict tree death

Publications Posted on: May 12, 2016
This review focused on the primary literature that described, modeled, or predicted the probability of postfire mortality in ponderosa pine (Pinus ponderosa) and Douglas-fir (Pseudotsuga menziesii).
