Current and future (end 21st-century) habitat suitability projections for Reynoutria and Ludwigia in Pacific Northwest watersheds using ensemble SDMs (6 model algorithms, 5 GCMs) under two societal climate scenarios

August 31, 2026

The data in this package includes the suitable habitat probability (SHP) rasters for the five-algorithm habitat suitability model ensemble. Multiple scenarios are included based on two shared-socioeconomic pathways (SSP245 and SSP585) and five global circulation models (GCM). The rasters include the SHP for each GCM (average, median, and standard deviation layers based on the five-algorithm ensemble), the GCM ensembles (average, median, standard deviation across GCM scenarios and average of the GCMs differenced with the hindcast representing the change in SHP), hindcast rasters centered on 1985, and the stream network buffers used to crop the rasters to the study area of interest. Data are provided for both Ludwigia spp. and Reynoutria spp. within their respective study areas: the Willamette Basin and the Washington Coastal Basin. The rasters are at a 1-km gridcell resolution and are provided as TIFF files. The stream network buffers are provided as shapefiles.
