How to estimate tree mortality resulting from underburning

Publications Posted on: July 31, 2019
Prescribed burning beneath standing timber is widely used to accomplish objectives such as preparing land for reforestation, reducing fuels, improving livestock range, and modifying wildlife habitat. Such burning is usually guided by written plans that set forth general objectives and a firing pattern to accomplish them.

Managing habitats for white-tailed deer in the Black Hills and Bear Lodge Mountains of South Dakota and Wyoming

Publications Posted on: February 26, 2019
The white-tailed deer is one of the most studied animals in North America, yet much of the available information has been derived in ecosystems different from the Black Hills. The Black Hills are unique in that the dominant species, ponderosa pine, has excellent regenerative abilities.

Seedbed characteristics in western larch forests after prescribed burning

Documents and Media Posted on: December 20, 2018
Removal of trees from western larch (Lariz occidentatis Nutt.) forests changes the energy and moisture budgets at the ground surface (fig. 1). The volume of timber removed, the means of its removal, and the aspect of the site influence the amount of direct and indirect sunlight reaching the forest floor and thus, the amount of heating of slash, duff, and upper soil.Document Type: Other Documents

Damage from logging and prescribed burning in partially cut Douglas-fir stands

Documents and Media Posted on: November 21, 2018
Damage from tractor logging and slash burning in a Douglas-fir stand on gentle terrain was measured for three different types of timber harvesting. Logging damage was light in the selection-cut and understory-removal cutting units. In the overstory-removal unit, about 11 percent of the leave trees were killed by logging.Document Type: Other Documents

Prescribed burning and productivity in southern pine forests: A review

Documents and Media Posted on: September 26, 2018
Fire is an ancient tool but still widely used in the management of southern pine forests. Fire is a relatively inexpensive tool and has a number of beneficial uses such as removing logging debris, reducing wildfire risk, increasing the abundance of certain understory species, and maintaining or restoring certain ecological conditions.Document Type: Other Documents

Forest structure and fire hazard in dry forests of the Western United States

Publications Posted on: August 01, 2018
Fire, in conjunction with landforms and climate, shapes the structure and function of forests throughout the Western United States, where millions of acres of forest lands contain accumulations of flammable fuel that are much higher than historical conditions owing to various forms of fire exclusion.

Importance of fuel treatment for limiting moderate-to-high intensity fire: Findings from comparative fire modeling

Publications Posted on: September 26, 2017
Context: Wildland fire intensity influences natural communities, soil properties, erosion, and sequestered carbon. Measuring effectiveness of fuel treatment for reducing area of higher intensity unplanned fire is argued to be more meaningful than determining effect on total unplanned area burned.

Recent emissions research in southwestern shrub and grassland fuels

Publications Posted on: August 21, 2017
While it is currently challenging to use prescribed burning in chaparral and other southwestern shrub fuel types due to many constraints, any such activities require smoke management planning. Information on fuels and emissions from chaparral were limited and based on older sampling systems. The DoD SERDP program funded a project to measure fuels and smoke emissions in the laboratory and field.

Fire and Smoke Model Evaluation Experiment (FASMEE): Modeling gaps and data needs

Publications Posted on: July 20, 2017
Fire and smoke models are numerical tools for simulating fire behavior, smoke dynamics, and air quality impacts of wildland fires. Fire models are developed based on the fundamental chemistry and physics of combustion and fire spread or statistical analysis of experimental data (Sullivan 2009). They provide information on fire spread and fuel consumption for safe and efficient prescribed (Rx) burning and wildfire suppression.

Long-term effects of fuel treatments on aboveground biomass accumulation in ponderosa pine forests of the northern Rocky Mountains

Publications Posted on: July 19, 2017
Fuel treatments in ponderosa pine forests of the northern Rocky Mountains are commonly used to modify fire behavior, but it is unclear how different fuel treatments impact the subsequent production and distribution of aboveground biomass, especially in the long term.
