| Summary: | Datasets used in: Young, A.M., Higuera, P.E., Duffy, P.A., and F.S. Hu. Climatic thresholds shape northern high-latitude fire regimes and imply vulnerability to future climate change. In Review at Ecography as of 10/2015. Description: The 'AK_VEG.tif' file contains vegetation classifications for each pixel in Alaska. There are five different vegetation types. Values 1-5 represent the following vegetation classifications: 1 - Wetland Tundra 2 - Shrub Tundra 3 - Graminoid Tundra 4 - Barren Tundra 5 - Boreal Forest Methods to use these maps to create the 'AK_VEG.tif' file are described in Young et al. (In Review). The 'ecor.tif' file is a map that classifies pixels in Alaska by ecoregion. The original ecoregion map is from (Nowacki et al. 2001). The main modification to the original ecoregions map was the addition of the Noatak River Watershed. The spatial coverage of the Noatak River Watershed was obtained from the perimeter of the Noatak National Preserve, available from: (). The original ecoregions map of Alaska is is in vector data format (i.e., polygons). We converted these data to a raster format using the "Feature to Raster" conversion tool in the "Conversion Toolbox" in ESRI Software ArcMap 10.1 Ecoregion identifications can be found in Fig. 1 of Young et al. (In Review). The 'TR.tif' file is a map of topographic ruggedness measured in meters. Methods used to create the topographic ruggedness are described in Young et al. (In Reveiw).
