Long-term effects of prescribed underburning on litter decomposition and nutrient release in ponderosa pine stands in central Oregon

Documents and Media Posted on: October 03, 2018
The effects of low-intensity prescribed underburning on the rates of litter decomposition and N and P release in ponderosa pine (Pinus ponderosa Dougl. ex. Laws) stands were studied by a litter-bag technique for 18 months in sites burned 0.3, 5, or 12 years earlier.Document Type: Other Documents

Prescribed fire: The fundamental solution

Publications Posted on: August 01, 2018
The theory and practice that embodies "learning organizations" can be applied to developing and implementing effective natural resource policy and management. A learning organization is a group of people who are continually enhancing their capacity to create the results they want. At the heart of learning organizations is systems thinking. This paper applies the language of systems thinking to our contemporary fire story.

Using prescribed fire to reduce the risk of large wildfires: A break-even analysis

Publications Posted on: August 01, 2018
Nearly all wildfires are extinguished when they are still small. The 3-5% that get out of control cause 95% of all wildfire-related costs and damages (Dodge 1972, Wilson 1985). There are two ways to deal with these problem fires. One practice is to limit fire by suppressing fires as soon as possible after they are detected.

Fire Effects Planning Framework: A user's guide

Publications Posted on: August 01, 2018
Each decision to suppress fire reinforces a feedback cycle in which fuels continue to accumulate, risk escalates, and the tendency to suppress fires grows (Miller and others, 2003). Existing decision-support tools focus primarily on the negative consequences of fire.

The effects of thinning and similar stand treatments on fire behavior in Western forests.

Publications Posted on: August 01, 2018
In the West, thinning and partial cuttings are being considered for treating millions of forested acres that are overstocked and prone to wildfire. The objectives of these treatments include tree growth redistribution, tree species regulation, timber harvest, wildlife habitat improvement, and wildfire-hazard reduction. Depending on the forest type and its structure, thinning has both positive and negative impacts on crown fire potential.

Smoke management guide for prescribed and wildland fire: 2001 edition.

The National Wildfire Coordinating Group's (NWCG) Fire Use Working Team has assumed overall responsibility for sponsoring the development and production of this revised Smoke Management Guide for Prescribed and Wildland Fire (the "Guide").

Overstory-derived surface fuels mediate plant species diversity in frequently burned longleaf pine forests

Publications Posted on: May 11, 2018
Frequently burned low-latitude coniferous forests maintain a high-diversity understory. Longleaf pine (Pinus palustris Mill.) forests and woodlands have exceptionally high diversity at fine scales and very frequent fire return intervals (1–3 yr). Furthermore, the positive association between high-frequency, low-intensity surface fires and high species richness in longleaf pine ecosystems is well documented but poorly understood.

Fuel: Logs, sticks, needles, duff, and much more

Publications Posted on: March 27, 2018
Fuels burned by either prescribed or wildfires are complex and important components of forested ecosystems. Fine fuels consisting of fallen limbs, twigs, and leaves of shrubs and trees are rich in nutrients. If these fuels are not immediately burned, nutrients can leach from these materials into the forest floor, especially if they overwinter.

Physical and chemical properties of the foliage of 10 live wildland fuels

Datasets Posted on: March 15, 2018
This data package contains data from over 3000 individual fuel elements collected as part of Joint Fire Science Program (JFSP) project 11-1-4-19 "Determination of the effects of heating mechanisms and moisture content on ignition of live fuels." Data were collected each month during one of two one-year periods.

RxCADRE 2012: In-situ fire behavior measurements

Datasets Posted on: March 15, 2018
This data publication contains fire behavior package (FBP) data; primarily flame temperature, horizontal and vertical mass flow, fire intensity, as well as ocular rates of spread (ROS), wind speed and direction data from the Prescribed Fire Combustion and Atmospheric Dynamics Research Experiment (RxCADRE) project conducted in November, 2012.
