The purpose of the Southern Wildfire Risk Assessment (SWRA) is to provide foundational information about wildfire hazard across all land ownership in the United States Forest Service Southern Region (Region 8). Such information supports fuel management planning decisions, as well as revisions to land and resource management plans. A wildfire risk assessment is a quantitative analysis of potential impacts by wildfire. |

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This spatial dataset was produced with the Wildfire Exposure Simulation Tool (WildEST), a cloud-based geospatial fire behavior characteristic simulation system. WildEST performs multiple deterministic simulations under a range of weather types (wind speed, wind direction, fuel moisture content) and weights those results based on weather type probabilities (WTP).</SPAN></P><P><SPAN /></P><P><SPAN STYLE="font-weight:bold;">This dataset represents a classification of the land near and surrounding buildings into zones that describe the wildfire risk mitigation activities appropriate for each zone. </SPAN></P><P><SPAN STYLE="font-weight:bold;">1: Direct Exposure--Burnable land cover within 75 m of a building > 40 m2. Buildings in this zone are exposed to ignition from convective and radiative heat from a wildfire, embers, and adjacent burning structures/outbuildings.</SPAN></P><P><SPAN STYLE="font-weight:bold;">2: Indirect Exposure--Nonburnable land cover within 75 m of a building > 40 m2 and less than 1530 m from a 500-ha contiguous block of wildland fuel. </SPAN></P><P><SPAN STYLE="font-weight:bold;">Buildings in this zone are exposed to ignition from embers and/or adjacent burning structures</SPAN></P><P><SPAN STYLE="font-weight:bold;">3: Little-to-no Exposure--Nonburnable land cover within 75 m of a building > 40 m2 and more than 1530 m from a 500-ha contiguous block of wildland fuel. Buildings in this zone are relatively safe from ember ignition and building-to-building spread. </SPAN></P><P><SPAN STYLE="font-weight:bold;">4: Critical Fireshed--the burnable land cover from which a wildfire can reach a significant number of buildings within a single burning period.</SPAN></P><P><SPAN STYLE="font-weight:bold;">8: Sources of Ember Load to Buildings--Burnable land cover more than 75 m from a building > 40 m2 that produces embers capable of reaching nearby buildings. Ember production is a function of fire type and intensity; ember travel is a function of wind speed and direction. Ember modeling is based on fire modeling based on gridded historical climatology.</SPAN></P></DIV></DIV></DIV> |
