Western root disease model simulation versus plot remeasurement: 11 years of change in stand structure and density induced by Armillaria root disease in Central Oregon

Publications Posted on: October 01, 2008
The purpose of this analysis was to use long term permanent plots to evaluate the short-term predictive capability of the Western Root Disease Model extension (WRDM) of the Forest Vegetation Simulator (FVS) in central Oregon mixed-conifer forests in project planning situations.

Modeling bark beetles and fuels on landscapes: A demonstration of ArcFuels and a discussion of possible model enhancements

Publications Posted on: October 01, 2008
The Westwide Pine Beetle Model and the Fire and Fuels Extension were used to simulate a mountain pine beetle outbreak under different fuel treatment scenarios on a 173,000 acre landscape on the Deschutes National Forest. The goal was to use these models within ArcFuels to analyze the interacting impacts of bark beetles and management activities on landscape fuel dynamics.

Incorporating landscape fuel treatment modeling into the Forest Vegetation Simulator

Publications Posted on: October 01, 2008
A simulation system was developed to explore how fuel treatments placed in random and optimal spatial patterns affect the growth and behavior of large fires when implemented at different rates over the course of five decades.

Effects of using visualization and animation in presentations to communities about forest succession and fire behavior potential

Publications Posted on: October 01, 2008
Natural resource managers use a variety of computer-mediated presentation methods to communicate management practices to the public. We explored the effects of using the Stand Visualization System to visualize and animate predictions from the Forest Vegetation Simulator-Fire and Fuels Extension in presentations explaining forest succession (forest growth and change over time), fire behavior, and management options.

FVS and global Warming: A prospectus for future development

Publications Posted on: October 01, 2008
Climate change-global warming and changes in precipitation-will cause changes in tree growth rates, mortality rates, the distribution of tree species, competition, and species interactions. An implicit assumption in FVS is that site quality will remain the same as it was during the time period observations used to calibrate the component models were made and that the site quality will not be affected by climate change.

Vegetation simulation and our changing world: Keynote address

Publications Posted on: October 01, 2008
Prior to the 1990s, a primary focus of vegetation management on National Forest System (NFS) lands was commodity production. While the production of goods is still important, the last 20 years has seen an emphasis in the restoration of ecosystem function and resiliency. This is illustrated by a decline of more than 80% in NFS timber production since the late 1980s.

Third Forest Vegetation Simulator Conference; 2007 February 13-15; Fort Collins, CO

Publications Posted on: September 30, 2008
The Forest Vegetation Simulator (FVS) is a suite of computer modeling tools for predicting the long-term effects of alternative forest management actions. FVS was developed in the early 1980s and is used throughout the United Sates and British Columbia. The Third FVS conference, held February 13-15, 2007, in Fort Collins Colorado, contains 20 papers.

A survey of effects of intentional burning on fuels and timber stands of ponderosa pine in Arizona

Publications Posted on: September 15, 2008
Limited intentional burning of ponderosa pine timberlands to achieve net benefits has been going on for years. Many statements of results have been published. Most statements have been based on small plot records or subjective observations. Hence, the statements have been questioned by some readers and have led to debate over the merits of intentionally burning ponderosa pine timberlands.

Wildland fire in ecosystems: fire and nonnative invasive plants

Publications Posted on: August 13, 2008
This state-of-knowledge review of information on relationships between wildland fire and nonnative invasive plants can assist fire managers and other land managers concerned with prevention, detection, and eradication or control of nonnative invasive plants.
