Below you will find links to the original spatial data compiled during the Pan-Africa freshwater assessment. The data are held in shapefiles, in ESRI native format, and contain the known range of each species mapped to the USGS Hydro 1K catchment layer (ranges are depicted as polygons). Currently this data is being migrated to the Hydrosheds catchment layer and these new shapefiles will be made available as soon as this process is complete. DBF files accompanying each polygon contain taxonomic information, and contain information on distribution status, sources and other details about the maps (see metadata document). To limit the size of the shapefiles that are available to download, the higher taxonomy is not included in the data sets, only the genus and species name.
