Data for: When do contemporary wildfires restore forest structures in the Sierra Nevada?

This dataset contains GeoTIFF raster layers derived from the analyses described in Chamberlain et al. (2024) ("When do contemporary wildfires restore overstore structures in Sierra Nevada forests"). Each layer represents classified predictions of the probability (using a 0.5 threshold) of restorative fire effects for the year 2020 under a mild (burning index = 53) and moderate (burning index = 71) fire weather scenario. The three layers include predicted probabilities for cover restoration, partial restoraiton, and full restoration. Cover restoration suggests that only canopy cover is likely to be restored in subsequent first-entry wildfires, partial restoration indicates that canopy cover and ladder fuel densities are likely to be restored, and full restoration indicates that canopy cover, ladder fuel density, and clump complexity are all likely to be restored. Please refer to the text in Chamberlain et al. (2024) for complete descriptions of each forest structure metric and how the restoration indices were defined.  The codes in each raster layer are as follows: NoData = outside study area 0 = restoration unlikely (probability < 0.5) under mild or moderate fire weather conditions 1 = restoration likely (probability > 0.5) under mild fire weather conditions 2 = restoration likely (probability > 0.5) under moderate fire weather conditions Terms of use: These data are solely for the purpose of general public information; the user should not rely upon the contents of this data for any specific purpose without making independent investigation. The authors assume no responsibility for any risk, loss, or liability that may result from the use of the data.

Shading and bars represent 95% credible intervals. Substrate categories are silt (Slt), sand (Snd), fine gravel (FGrav), coarse gravel (CGrav), cobble (Cob), boulder (Bld), and bedrock (Bed).
