WWETAC is committed to providing tools to visualize wildland threats and the resources they potentially affect using the latest geospatial technology. The TRM family of web maps and tools can be used to explore relationships between wildland threats and high value resources, or to focus on a specific topic such as phenology, seed zones, or climate change.
The TRM WebMap is an interactive 2D map that displays in your web browser - no software installation required. It contains CONUS -wide wildland threat (wildfire risk, insect and disease risk, fragmentation, climate change) and highly-valued resource data (residential structures, energy infrastructure, watersheds, recreation and historical sites) wildland threats in relation to highly valued resources.

To navigate around the map - L click and drag your mouse to pan, use your mouse wheel or the slider control in the upper left to zoom, and Shift L click and drag to define a new map extent.
TRM Open-Source Cloud WebMap
This version of the TRM WebMap utilizes Open-Source Software and Cloud Server technology. Use the ‘Customizable Map’ to add new map services and save the map and share with other users.
Intersecting wildland threat spatial data can provide meaningful information to policymakers, but doing so in a valid manner is critical. This map presents intersected threat data for the Northwestern US developed using a novel neighborhood analysis technique. Future research will extend these methods to the conterminous US.
Selection of seed sources that are well adapted to a specific site is essential in restoration project. Using climate data and common garden studies, seed zones have bee developed to help in the selection of sit-adapted seed sources. Use the above link to access the web map and associated GIS data.
This web map displays the current "greeness" of the vegetation across the western US using products derived from eMODIS NDVI data. These layers are updated weekly to provide a near-real-time assessment of land surface phenology.
The Western Wildfire Risk Explorer (WWRE) application summarizes burn probability and conditional flame length by subwatershed level for western US national forests (west of 100th meridian). Tabular reports of mean burn probability and flame length by watershed are available for all western US national forests.
Climate change data models typically use global atmospheric circulation models and other inputs that limit their spatial resolution, making these products difficult to interpret at larger scales. To address this issue, global climate change data have been downscaled by the Climate Impacts Group. These downscaled products are 5 km in resolution and are presented in this web map for the western US.
Annual aerial surveys are conducted over all forested lands in the US and the data collected are used in a variety of formats to support management activities and in monitoring forest health. USFS Region 6 (OR and WA) have developed a product that summarizes the tree mortality and defoliation recorded by the aerial surveyors.
BioMAP is a dynamic global vegetation model created by hybridizing the Biome-BGC ecosystem model and the MAPSS biogeography model and adding a process-based fire model. It simulates vegetation response to climate change over centuries, and can be used to predict vegetation type shifts, carbon storage, evapotranspiration and runoff for at scales from a single plot to regions, continents and the globe. This web map presents vegetation simulations for several climate models and emission scenarios for the state of CA. .
USDA APHIS researchers have developed a risk of gypsy moth establishment model using BioSIM software; inputs include life history of the gypsy moth, historic climate records, and available host. This web map shows the establishment probability for OR with 1 = high probability, 0 = low probability for the years 2010 and 2012.
