These species range tables contain the HydroBASINS ID field which can be joined to the HydroBASINS spatial data. Points as a csv (comma separated value) table including the latitude and longitude of each observation.įreshwater HydroBASIN Tables in csv format. Freshwater species are mapped to pre-defined river/lake catchment units called HydroBASINS. It is widely accepted that the river/lake catchment is the most appropriate management unit for inland waters. Note that sometimes the range is incomplete. ![]() Polygons in Esri shapefile format, containing the known range of each species. Most species will have either polygons or points, only some have both: The data are made available in three formats, including taxonomic information, distribution status, IUCN Red List Category, sources and other details about the maps (see metadata document). It is important to note that some species (such as those listed as Data Deficient) are not mapped and subspecies, varieties and subpopulations are mapped within the parent species. The spatial data provided below are mostly for comprehensively assessed taxonomic groups and selected freshwater groups. More than 82% of these (>123,600 species) have spatial data. The IUCN Red List of Threatened Species ™ contains global assessments for more than 150,300 species. ![]() Scientific Papers - Analyses Spatial Data Download ![]()
