Endangered taxon (abbreviation EN, from English Endangered) is a degree of threat according to the IUCN red list. Endangered taxa face a high risk of extinction in the near future. In the vast majority of cases, these are organisms threatened by the expanding human civilization.
List of endangered species
In addition to the list of endangered species / taxa issued by the International Union for Conservation of Nature (see IUCN Red List), individual states also have their own lists of local endangered species / taxa. A concrete example is, for example, the list of endangered animals in the Czech Republic (see also the degree of endangerment in the Czech Republic).
