Name: 2018 Burn Severity

Display Field: FireNum

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This burn severity classification is based on the near infrared (NIR) and short wave infrared (SWIR) bands of pre- and post-fire Landsat 8 imagery. This data was created using post-fire imagery from shortly after a fire was declared out or was considered to have stopped growing in size. Burn severity run immediately post-fire may not capture the true impact on vegetation; heat damage to vegetation (i.e. needle drop) may not be fully realized until a full growing season has passed, and so this classifcation may over- or under-estimate some burn severity catgories, particularly in areas of dense canopy cover where the ground may not be visible in the post-fire satellite imagery.Early season fires may be fully classed as unburned due to a comination of lower fire intensity and rapid vegetation green-up in the spring.Default breakpoint values (based on research by the US Forest Service) are used for all fires across the province, regardless of fuel/timber types:0-75 = unburned76-109 = low110-187 = medium/moderate188-255 = high
