Kingdom Phylum Class Order Family
ANIMALIA CHORDATA MAMMALIA RODENTIA SCIURIDAE

Scientific Name: Sciurus lis
Species Authority: Temminck, 1844
Common Name(s):
English Japanese Squirrel

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Ishii, N. & Kaneko, Y.
Reviewer(s): Amori, G. (Small Nonvolant Mammal Red List Authority) & Chanson, J. (Global Mammal Assessment Team)
Justification:
Listed as Least Concern, because it is relatively widespread, common throughout most of its range, and there are no major threats to the species overall.

Geographic Range [top]

Range Description: This species is endemic to Japan. It is widely distributed in north-eastern Honshu, and is rare in western Honshu, from the Chugoku District (Japan RDB, 2002; Abe, et al., 2005). It is also found on Shikoku (Japan RDB, 2002; Abe, et al., 2005), and on Awaji Island, where there have been no recent sightings (Abe, et al., 2005). It is unclear whether the species ever occurred on Kyushu.

Population [top]

Population: It is common over most of its range, but rare in some parts, such as western Honshu. It can occur at relatively large densities in lower montane pine forests (Abe, et al., 2005).
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: This species is found in lowland to subalpine primary and secondary pine forests.
Systems: Terrestrial

Threats [top]

Major Threat(s): There are no major threats, although the population has possibly been affected by die-offs of native pine trees due to an invasive disease (Japan RDB, 2002). The impact of the introduction of Sciurus vulgaris around Tokyo (in the late 1990s) and other areas requires further investigation to determine whether the two species are competing or hybridizing.

Conservation Actions [top]

Conservation Actions: It is present in a number of protected areas. Research into the impact of the introduced species Sciurus vulgaris is needed.
