The Fireshed Registry is a geospatial dashboard and decision tool built to organize information about wildfire transmission to communities and monitor progress towards risk reduction for communities from management investments. The concept behind the Fireshed Registry is to identify and map the source of exposure rather than mapping the value at risk across all lands in the conterminous United States. Risk is composed of three components: (1) ignition likelihood, (2) expected fire intensity, and (3) effects related to expected fire intensity. Wildfire exposure, by contrast, only concerns the juxtaposition of threatened values in relation to predicted fire occurrence and intensity without estimating potential loss. Exposure is the measure of structures that are exposed to fires that originate within the Fireshed or Project Area. The annual average measure is constructed by averaging potential exposure from the \"FSIM\" fire simulation database. Fire simulations are based on fuel conditions in 2014. Structures are based on Microsoft Building Footprints identified using a computer vision algorithm on imagery from 2012 - 2016. Exposure measures are adjusted where wildfire or management activities have changed the fuel conditions since 2014. While the Fireshed Registry was organized around mapping the source of fire risk to communities, the framework does not preclude the assessment of other resource management priorities and trends such as water, fish and aquatic or wildlife habitat, or recreation. The Fireshed Registry is also a multi-scale decision tool for quantifying, prioritizing, and geospatially displaying wildfire transmission to buildings in adjacent or nearby communities. Fireshed areas in the Fireshed Registry are approximately 250,000 acre accounting units that are delineated based on a smoothed building exposure map of the conterminous United States. These boundaries were created by dividing up the landscape into regular-sized units that represent similar source levels of community exposure to wildfire risk. Project areas are approximately 25,000 acre accounting units nested within firesheds. The fireshed and project area boundaries are designed to delineate hotspots of fire transmission to adjacent or nearby communities to facilitate cohesive cross-boundary risk mitigation planning.<\/SPAN><\/P><\/DIV><\/DIV><\/DIV>", "summary": "The Project Area exposure data are designed to be joined to the Fireshed Registry Project Areas, matching on the PA_ID field.
