Geographic Range [top]

Range Description:This species has been recorded only from relict populations in montane areas of central Honshu, Japan, at altitudes of 900 to 2,900 m asl. It has been found in the Japan Alps, Okuchichibu and Shigayama (Abe et al. 2005). The species has not been found on northern Honshu where the mountains are usually lower in height (usually less than 1,500 m asl), and where the Shinto Shrew (Sorex shinto) is more common.

Population [top]

Population:The population appears to be small, though stable. It is not as common as Sorex shinto.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It inhabits grasslands, shrublands and coniferous forests in subalpine to alpine habitat; and is rarely found in forests at lower altitudes.
Generation Length (years):1

Threats [top]

Major Threat(s): The species occurs primarily at elevations above 1,000 m asl, and so there currently are very few major threats. However, human encroachment and development of tourist facilities, such as ski resorts, may be a localized threat. Competition with Sorex shinto may be a problem. Because the species is restricted to montane habitat fragments it may be susceptible to climate change in the future.

Conservation Actions [top]

Conservation Actions: This species has been recorded from several National Parks and protected areas, although the degree of protection within these areas varies greatly.
