This layer contains a footprint that represents the intersection of the "Wildfire Footprint (> 100 acres) (2000-2022)" data layer and the "Bark Beetle Footprint (2000-2022)" data layer.Wildfires (2000–2022). This dataset illustrates how increasing atmospheric dryness increases vegetation's flammability and susceptibility of trees to mortality by bark beetles. The dataset covers the years 2000–2022. It was derived from this data source: cumulative wildfire and wildland fire use perimeters greater than 1,000 acres in the western US and 500 acres in the eastern US ( MTBS - https://mtbs.gov/project-overview).Areas With Bark Beetle Mortality (2000–2022). This dataset illustrates how chronic precipitation deficits increase vegetation's flammability and susceptibility of trees to mortality by bark beetles. The dataset covers the years 2000–2022. It was derived from this data source: cumulative areas with bark beetle mortality mapped by Forest Health Protection and Partners (https://www.fs.usda.gov/science-technology/data-tools-products/fhp-mapping-reporting/detection-surveys).
