One of the main reasons cited for inadequate representation of biodiversity is a lack of readily available information on the status and distribution of inland water taxa.

In response to this need for information, the IUCN Species Programme, in collaboration with Zoo Outreach Organisation (ZOO) conducted the Eastern Himalaya Freshwater Biodiversity Assessment, a review of the global conservation status of 1,073 freshwater species belonging to three taxonomic groups – fishes (520 taxa), molluscs (186 taxa), and odonata (dragonflies and damselflies) (367 taxa). 

Other groups that include freshwater species that have been comprehensively assessed are freshwater crabs (assessed in 2008, and 57 species of crab are present within the assessment region), mammals, birds, and amphibians and their assessments can be accessed on the IUCN Red List.
