ArcFuels for Fuel Treatment Planning

Fire behavior modeling and geospatial analyses can provide tremendous insight for land managers as they grapple with the complex problems frequently encountered in wildfire risk assessments and fire and fuels management planning. Fuel management often is a particularly complicated process where the benefits and potential impacts of fuel treatments need to be demonstrated in the context of land management goals and public expectations. The fuel treatment planning process is complicated by the lack of data assimilation among fire behavior models and weak linkages to geographic information systems, corporate data, and desktop office software. ArcFuels is a streamlined fuel management planning and wildfire risk assessment system which creates a trans-scale (stand to large landscape) interface to apply various forest growth (FVS/FFE-FVS) and fire behavior models (i.e. FlamMap, BehavePlus) within ArcMap to design and test fuel treatment alternatives. ArcFuels has been implemented on Citrix at the Forest Service Enterprise Production Data Center, eliminating the need for desktop GIS, improving connectivity to the corporate geospatial databases housed at the data centers, and enabling sharing of information among Forest Service employees.

Landscape Treatment Designer (LTD) for Fuel Treatment Planning

The LTD program is a multicriteria optimization routine to help design fuel treatment scenarios according to spatial and non-spatial objectives. The input data represent polygons that are attributed with information about expected fire behavior and the polygons overall contribution to one or more landscape management objectives. These can include non-spatial attributes such as stand conditions, and/or spatial attributes like the distance to fire susceptible landscape features like critical habitat or residential structures. The user supplies a treatment constraint that represents the maximum area that can be treated based on budgets or other constraints. In a simple application, the program operates the same as sorting a shapefile attribute table based on fields of interest and then selecting polygons from the sorted list until some total area limit is met. However, LTD automates the process and allows for combining several attributes in weighted combinations so that treatment alternatives can be quickly generated and mapped. A non-adjacency problem would allocate treatments based on objective values regardless of their location relative to each other. LTD also has adjacency constraints that allow it to coordinate treatments and build patches that can serve as wildland fire use areas or large scale prescribed fire treatment areas.

Geospatial Task Group (GTG) Web site and Clearinghouse

The GTG Web site is a coordinated point of contact on the use of geospatial data and applications in support of wildland fire management. The GTG supports wildland fire activities and advises on wildland fire geospatial data standards, and provides a forum for sharing geospatial technology in wildland fire management.

FRAMES: Technology in Support of Wildland Fire Research and Management

"Information needed to support fire management will be developed through an integrated interagency fire science program. Scientific results must be made available to managers in a timely manner and must be used in the development of land management plans, fire management plans, and implementation plans." [National Fire & Aviation Executive Board, Task Group Briefing Paper #1 (September 2004)]

Threat News ViewerWildland Threat News Explorer Tool

The WWETAC Threat News Explorer is a custom media search site that uses the Google news search engine to locate articles relevant to wildland threats. The site is a convenient way to track ongoing news about wildfires, bark beetles, climate change, and other important wildland threats. The site is hosted on an Amazon elastic cloud and is one of the first applications in the Forest Service that employs cloud computing technology. WWETAC welcomes comments and suggestions on the site.

Forest ThreatForest Threat Viewing Tool

The Eastern Forest Environmental Threat Assessment Center (EFETAC) recently launched its forest threats summary viewer for viewing maps and summary information on key threats in the Eastern U.S. The tool was developed in partnership with the University of North Carolina Asheville's National Environmental Modeling and Analysis Center (NEMAC).

See the press release in Science Daily.

The Web viewer allows searches by threat or state, and threats are classified into invasive plants, insects and diseases, loss of open space, climate change, and wildland fire. the site also provides linkages to other federal, state, and local resources that offer additional in depth information.

The tool is available at the EFETAC's Web site.

Climate Change ToolsClimate Change

World Resources Institute (WRI) Climate Analysis Indicators Tool

The Climate Analysis Indicators Tool (CAIT) by WRI is a set of comprehensive and comparable greenhouse gas inventories, together with other climate-relevant indicators. CAIT can be used to analyze a wide range of climate-related data questions and help support policy decisionmaking and discussions under the climate convention and in other forums.

Carbon Inventory, Management and Reporting

Accurate estimates of carbon in forests are crucial for forest carbon management, carbon credit trading, national reporting of greenhouse gas inventories to the United Nations Framework Convention for Climate Change, calculating estimates for the Montreal Process criteria and indicators for sustainable forest management, and registering forest-related activities for the national 1605(b) Voluntary Reporting of Greenhouse Gases Program and other greenhouse gas registries for States and regions.

WWETAC Project with the the GMWEST Model

The GMWest was specifically developed to evaluate the risk of establishment for detected gypsy moth introductions in the state of Utah, although from the beginning we envisioned a risk assessment system that would be applicable to all portions of the Western United States. System development first required acquiring a variety of databases regarding landscape features, vegetation, and weather/climate variables. Next, "probability of establishment" maps were produced using weather and climate variables from the database as input to a validated gypsy moth phenology model. A "hazard of establishment" map layer was produced that could be combined using GIS with other layers in the database (host distribution, land use, demographic, topographic and transportation) to produce a "risk of establishment" map. As GMWest produces geo-referenced data layers that are combined and manipulated by a GIS, the system is extremely flexible and adaptable.

The National Invasive Species Information Center (NISIC)

The National Invasive Species Information Center (NISIC) was established in 2005 at the National Agricultural Library to meet the information needs of users including the National Invasive Species Council (Council). NISIC creates and manages the www.invasivespeciesinfo.gov Web site. The Web site serves as a reference gateway to information, organizations, and services about invasive species.
