Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2016-08-18
Assessor(s): Henttonen, H.
Reviewer(s): Amori, G.
This species has a wide range. The population size has not been quantified, but it is not believed to approach the thresholds for the population size criterion of the IUCN Red List (i.e. less than 10,000 mature individuals in conjunction with appropriate decline rates and subpopulation qualifiers). Although there may have been some population declines as a result of logging, it is not believed to approach the threshold for the population decline criterion of the IUCN Red List (i.e. declining more than 30% in ten years or three generations). For these reasons, it is evaluated as Least Concern.

Geographic Range [top]

Range Description:Myopus schisticolor has a wide distribution in the northern Palaearctic, ranging from western Norway, through Sweden and Finland through northern and central Russia to the Pacific coast and Sakhalin island (Russia) (Shenbrot and Krasnov 2005). It occurs at altitudes from 600 to 2,450 m (Nowak 1999).

Population [top]

Population:Population densities in this species are typically very low, although infrequently there may be population irruptions and local migrations. Such events occurred in northern Finland in 1910, 1957-58 and 1963 (Sulkava 1999). In Fennoscandia local population declines may have occurred as a result of logging (Sulkava 1999, H. Henttonen pers. comm. 2006).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:The species inhabits old spruce forest and taiga forest, where breeding tends to occur in areas with abundant mosses (Pleurozium, Dicranum, and Hylocomium spp.), which provide a critical winter food source. In the summer, marshy areas within forests and pine-bogs with a high dwarf shrub layer are used, and in years of high population density dry forests and even clear-cuts may be occupied (Sulkava 1999). The species is found in the taiga and not above the treeline.
Generation Length (years):0-1

Threats [top]

Major Threat(s): There are no major threats. The species may be locally affected by logging of old-growth spruce forest, its main habitat, in some parts of its range (H. Henttonen pers. comm. 2006).

Conservation Actions [top]

Conservation Actions: The species is found in protected areas.

Errata [top]

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