Reviewer(s): Amori, G. (Small Nonvolant Mammal Red List Authority) & Temple, H. (Global Mammal Assessment Team)
Justification:
This species has a large population size and a wide distribution. No decline in population size has been detected, and there are no known widespread major threats. Least Concern.

Population [top]

Population: Europe: It is generally less common than its congener the common shrew, but it is nevertheless a widespread and abundant species (Sulkava 1990). Populations are thought to be stable, with interannual fluctuations that follow no particular cycle (Pucek 1999). In eastern Karelia, where population density has best been studied, tenfold fluctuations have been recorded (Sulkava 1990). Japan: Common in the forests of Hokkaido. Mongolia: Abundant and widespread, most common in Hentii Mountain Range. This species can survive in most habitat types, preferentially forested habitats.
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: It occurs mainly in coniferous, deciduous and mixed forests in the taiga zone, although it is also found in a range of tundra habitats including birch and willow scrub in river valleys (Pucek 1999, Finch and van der Kooij 2005). In northern Fennoscandia, it tends to be found in shrub-rich mires, alpine birch forests, and open mires, and at the south-western edge of its range in Norway it occurs in alpine habitats (Finch and van der Kooij 2005). In general moist habitats are preferred, such as damp parts of forests with thick moss cover (Pucek 1999). Cultivated land is avoided (Sulkava 1990). The masked shrew feeds on a wide range of insects, spiders, and centipedes (Stone 1995). As it has a lower net food intake than larger shrews such as S. araneus, it can survive in less productive habitats (Finch and van der Kooij 2005).
Systems: Terrestrial

Threats [top]

Major Threat(s): Extensive logging is a general threat to habitat and may affect local populations. However, at the global scale the population is not considered under serious threat from this.

Conservation Actions [top]

Conservation Actions: It is listed on Appendix III of the Bern Convention. It occurs in many protected areas.
