Mongolian Red List of Reptiles and Amphibians - Web - Zoological ...

STATUS OF MONGOLIAN REPTILES AND AMPHIBIANS
Of the 24 native Mongolian reptile and amphibian species that were assessed, 25% are
categorised as regionally threatened, all of which are categorised as Vulnerable (VU) (Figure
2). A further 21% are categorised as Near Threatened (NT). Just 4% are categorised as Data
Defi cient (DD). Fifty percent of the reptiles and amphibians of Mongolia were categorised as
Least Concern (LC). A further three species were categorised as Not Applicable, as they did
not meet the requirements for regional assessment (see notes on application of the guidelines).

Figure 2. Regional conservation status of the 24 native Mongolian reptiles and amphibians according to the
IUCN Red List Categories and Criteria. VU = Vulnerable, NT = Near Threatened, DD = Data Defi cient,
LC = Least Concern.
Figure 3 illustrates that there are different trends highlighted when the species are divided into
reptiles and amphibians. It has long been known that reptile and amphibian species display
many differences between the two orders, and are infl uenced by entirely different factors.
Amphibians
The majority (67%) of Mongolia’s amphibian species (orders Anura and Caudata) are
categorised as VU. This includes Pewzow’s toad (Bufo pewzowi) and the Siberian salamander
(Salamandrella keyserlingii). The remaining 33% are categorised as LC.
Reptiles
Categorisation of the reptile species (order Squamata) was more varied, with 11% classifi ed as
VU, 28% as NT, and 6% being DD. The remaining 55% were classifi ed as LC.
