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. Click here for data layer descriptions/metadata summaries and links. 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.
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 conterminous US using products based on eMODIS NDVI data. These layers are updated weekly to provide a near-real-time assessment of land surface phenology. NWS Weekly percipitation estimates are also displayed.
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.
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.
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.
