Method

Method Overview: Our study’s methodology was based on a vulnerability assessment framework developed by Oliveira et al. (2018). Structurally, vulnerability is modeled as the combination of exposure, sensitivity and coping capacity. Exposure data represents burnable assets, sensitivity is a modifier of exposure, representing the degree to which exposure variables may be affected by wildfire. Coping capacity, represents protective factors at the regional or community level. The procedure involved processing individual map layers covering the study areas, and representing the measure of interest (see below for thorough description). Each individual layer was normalized to range from 0 to 1, unless the variable was dichotomous. The Oliveira et al. (2018) framework relied on joining the individual normalized layers to a 1ha squared grid, with each grid cell acting as a raster grid cell throughout all study phases. For each individual layer, we linked   In contrast to the Oliveira (2018) framework, we converted the individual layers into raster layers and combined them into four indices.
