Percent canopy cover and stand structure statistics from the Forest Vegetation Simulator

Publications Posted on: August 01, 2018
Estimates of percent canopy cover generated by the Forest Vegetation Simulator (FVS) are corrected for crown overlap using an equation presented in this paper. A comparison of the new cover estimate to some others is provided. The cover estimate is one of several describing stand structure.

Evaluating cost-effectiveness of multi-purpose fuel treatments in western dry mixed-conifer forest considering hazard, risk, longevity, and co-benefits

Projects Posted on: August 18, 2016
The research objective is to evaluate the effectiveness and cost-effectiveness of a broad range of fuel treatment designs, patterned on treatments applied to dry mixed conifer forest, which address multiple components of resistance to fire in diverse forest settings. The project design accounts for fuel treatment longevity by considering and comparing the effectiveness and costs of treatment over a multi-decade planning horizon, addressing the challenge of rating cost-effectiveness in the context of multiple treatment and land management objectives, and providing a framework for assessing the stand-level effects of fuel treatment on fire behavior and resistance to fire.

The Fire and Fuels Extension to the Forest Vegetation Simulator

Publications Posted on: May 12, 2016
The Fire and Fuels Extension (FFE) to the Forest Vegetation Simulator (FVS) simulates fuel dynamics and potential fire behaviour over time, in the context of stand development and management. Existing models of fire behavior and fire effects were added to FVS to form this extension. New submodels representing snag and fuel dynamics were created to complete the linkages. This report contains four chapters.

Development of full regeneration establishment models for the forest vegetation simulator

Publications Posted on: January 28, 2016
For most simulation modeling efforts, the goal of model developers is to produce simulations that are the best representations of realism as possible. Achieving this goal commonly requires a considerable amount of data to set the initial parameters, followed by validation and model improvement – both of which require even more data.

Simulating post-wildfire forest trajectories under alternative climate and management scenarios

Publications Posted on: July 08, 2015
Post-fire predictions of forest recovery under future climate change and management actions are necessary for forest managers to make decisions about treatments. We applied the Climate-Forest Vegetation Simulator (Climate-FVS), a new version of a widely used forest management model, to compare alternative climate and management scenarios in a severely burned multispecies forest of Arizona, USA.

A simulation study of thinning and fuel treatments on a wildland-urban interface in eastern Oregon, USA

Publications Posted on: October 03, 2012
We simulated long-term forest management activities on 16,000-ha wildland-urban interface in the Blue Mountains near La Grande, Oregon. The study area is targeted for thinning and fuels treatments on both private and Federally managed lands to address forest health and sustainability concerns and reduce the risk of severe wildfire.

Forest biomass and tree planting for fossil fuel offsets in the Colorado Front Range

Publications Posted on: February 09, 2011
This study estimates the amount of carbon available for removal in fuel reduction and reforestation treatments in montane forests of the Colorado Front Range based on site productivity, pre-treatment basal area, and planting density. Thinning dense stands will yield the greatest offsets for biomass fuel. However, this will also yield the greatest carbon losses, if the removals remain on site to decompose.

Using FIA data in the Forest Vegetation Simulator

Publications Posted on: July 15, 2009
The Forest Vegetation Simulator (FVS) is a national system of forest growth models maintained by the USDA Forest Service. It is the official tool for stand growth projection on National Forest lands, but it is also used widely on other ownerships. Model extensions and post-processors permit FVS users to perform a broad range of functions, including silvicultural manipulations, wildlife habitat analyses, and fuel treatment evaluations.

Chapter 4: Variant descriptions

Publications Posted on: June 17, 2009
The Fire and Fuels Extension (FFE) to the Forest Vegetation Simulator (FVS) simulates fuel dynamics and potential fire behavior over time, in the context of stand development and management. This report documents differences between geographic variants of the FFE.

User's guide [Chapter 3]

Publications Posted on: June 17, 2009
The Fire and Fuels Extension (FFE) to the Forest Vegetation Simulator (FVS) simulates fuel dynamics and potential fire behavior over time, in the context of stand development and management. This chapter presents the model's options, provides annotated examples, describes the outputs, and describes how to use and apply the model.
