State-and-Transition Simulation Model (ST-Sim)

Learn more and access ST-Sim tool 

Using computer-aided modeling, land management teams can use ST-Sim to document or justify management actions in forthcoming forest plans and NEPA documentation. ST-Sim allows managers to ask landscape-wide “what-if” questions based on different management regimes and land treatments while estimating interactions with expected climate changes. With this tool, the scientists are able to provide land managers with worst-case and best-case scenarios under different conditions.

FOFEM – First Order Fire Effects Model

Access tool.

FOFEM (a First Order Fire Effects Model) is a computer program for predicting tree mortality, fuel consumption, smoke production, and soil heating caused by prescribed fire or wildfire.

Provisional Modeling Dynamic Fuels with an Index System (MoD-FIS) for the Great Basin

Access MoD-FIS tool.

The MoD-FIS tool seasonally modulates fuel model data in the Great Basin and Southwest regions. MoD-FIS incorporates seasonal variability of herbaceous cover. These fine fuel measurements are then used to capture changes to fire behavior fuel models based on the current fire season herbaceous production.

BehavePlus Fire Modeling System

Access BehavePlus v6 Beta.

Behave Plus is a Windows-based computer program that can be used for any fire management application that involves modeling fire behavior and fire effects. The system is composed of a collection of mathematical models that describe fire behavior, fire effects, and the fire environment. The program simulates rate of fire spread, spotting distance, scorch height, tree mortality, fuel moisture, wind adjustment factor, and many other fire behaviors and effects; so it is commonly used to predict fire behavior in several situations.

Development of the Rangeland Vegetation Simulator: A module of the Forest Vegetation Simulator

View report.

This report discusses development of the Rangeland Vegetation Simulator (RVS) and new models for estimating understory conditions in forested landscapes. The RVS is calibrated on 112 unique sites and enables simulation of ecological dynamics, production and fuels in either a spatially explicit manner or as a processor of inventory data much like the FVS. Validation of the RVS, in this inaugural development, suggests significant promise for its use to describe vegetation and fuel data when the structure and composition are given, but its ability to describe succession is limited and in some cases unrealistic.

The premier outputs of the vegetation simulator are:
1) Standing biomass, carbon, and annual production of herbs and shrubs (including standing dead herbaceous material).
2) Vegetation structure, composition, and seral stage
3) Fuelbed properties (1, 10, 100, 1000 hr fuel) and fire behavior fuel models
4) Response of these attributes to herbivory and fire
