Concluding Remarks About Freshwater Decapod Conservation

Invertebrates in general are the most species-rich group of organisms on the planet. At the same time invertebrates are the most poorly known and include the highest number of threatened species, and this is especially true for those species that live in freshwater habitats. The different aspects of freshwater decapod conservation covered in this book leave us in no doubt that a high proportion of this important group of organisms are threated with extinction, mainly from anthropogenic impacts. The IUCN Red List assessments quantify extinction threats for groups of organisms globally but the coverage, with only 3.4 % of all species represented, is far from complete, particularly invertebrates. For example, 61 % of vertebrate species are represented on the IUCN Red List compared to only 1.2 % of invertebrates. The current rate of description of new species of freshwater decapods is given, along with the recorded rates of species extinction, and future prospects are discussed.
