Taxonomy [top]

Kingdom Phylum Class Order Family
Animalia Chordata Mammalia Eulipotyphla Talpidae

Scientific Name: Mogera tokudae Kuroda, 1940
Common Name(s):
English Sado Mole, Tokuda's Mole
Taxonomic Notes: Yoshiyuki and Imaizumi (1991) named the Honshu population as a separate species, Mogera etigo, but Abe (1995, 1996) ascribed the differences between the Sado and Honshu population to geographical size variation. However, considerable genetic (Tsuchiya et al., 2000) and karyological differences exist (Kawada et al. 2001) and hence they are both recognised here.

Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2016
Date Assessed: 2015-10-15
Assessor(s): Kennerley, R.
Reviewer(s): Amori, G.
Contributor(s): Abe, H. & Hashimoto, T.
Listed as Near Threatened, because its extent of occurrence is less than 2,000 km², it is confined only to Sado Island, and although common, the species has experienced a decline due to a reduction in the quality of its habitat. However, populations are now thought to be stabilizing as threats to habitats are declining and overall it does not qualify for a more threatened category. Almost qualifies as threatened under criterion B1.

Habitat and Ecology [top]

Habitat and Ecology:It is present in a range of habitats, including temperate forest, shrubland, grassland and cultivated fields (Abe et al. 2005).

Use and Trade [top]

Use and Trade: Use and trade information is unknown.

Threats [top]

Major Threat(s): The species mainly occurs in alluvial plain with deep soil, where agricultural reclamation has been carried out since the 1970s and consequently the species' preferred habitats have decreased. The habitat alteration continues but the pace is currently slowing down. Therefore, it is expected that their population is stabilizing although currently it is still in decline. Unlike the situation with Mogera etigo, there are no competitors, and therefore the species is probably not in decline as with the conspecific on the Etigo Plain.

Conservation Actions [top]

Conservation Actions: It has not been recorded from any protected areas. Quasi National Park on the island is primarily for shoreline habitats. It is listed as Near Threatened (NT) in the Japanese Red List (2007).

Errata [top]

Errata reason: This errata assessment has been created because the map was accidentally left out of the version published previously.
