Name: Exposure to Wildfire Exclusion

Display Field: Fireshed_N

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This data layer displays the percent of forested area in each fireshed that is experiencing a fire deficit over the last 100 years: Very Low (less than 45% of forested area); Low (45 to 58% of forested area); Moderate (58 to 70% of forested area); High (70 to 83% of forested area); and Very High (greater than 83% of forested area). Fire deficit was determined for each 30-m pixel by comparing observed fire frequencies from 1923 to 2023 to historical mean fire return intervals (MFRI from LANDFIRE). The ratio of observed to historical fire frequencies was used to determine pixels that are burning less frequently than expected and therefore have deficit in fire. The area represented by these pixels compared to the area forested within the fireshed was used to determine the percent of forested area in the fireshed experiencing a fire deficit. This percentage was the input value into the Mature and Old Growth Condition Assessment (MOG-CA, an Ecosystem Management Decision Support-based logic model) to produce the fire deficit scores. The MOG-CA leveraged thresholds to convert these values into scores ranging from +1 (Very Good Condition, Very Low Risk) to -1 (Very Poor Condition, Very High Risk).Spatial Extent: CONUSUnits: "Categories of % of area:Very Low (<45% of area)Low (45-58% of area)Moderate (58-70% of area)High (70-83% of area)Very High (>83% of area)"
