Scientific Name: Ochotona koslowi (Büchner, 1894)
Common Name(s):

Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii) ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Smith, A.T. & Johnston, C.H.
Reviewer(s): Boyer, A.F. & Johnston, C.H. (Lagomorph Red List Authority)
Ochotona koslowi was first described in 1884 and was subsequently not seen again until the 1980s (Smith et al. 1990). It is listed as Endangered because its extent of occurrence is less than 5,000 km², it is known from fewer than five locations, and there is a continuing decline in the extent and quality of its habitat.

Geographic Range [top]

Range Description:Ochotona koslowi is endemic to China (Smith and Xie 2008). A 1999 survey concluded that O. koslowi occurs in three localities; "(i) the Valley of the Winds, where the type specimens were collected (the exact location is not clear, but it is conjectured to be in the central or west Kunlun Mountains); (ii) the juncture of the Kunlun and Kala-Kunlun mountains, which is located south-east of Mount Kongke; and (iii) in the Arjin Mountain Nature Reserve, including the areas verified in 1984, 1988 and during the current survey. During the present investigation, it was verified that the distribution is nearly continuous between Aqik Lake, Yueya River and Tuzi Lake. The distance between these three limits is 800 km east to west, running parallel to the Kala-Kunlun mountains, where the distribution of Koslov's pika is limited and discontinuous" (Li et al. 2006). It is speculated that its distribution may extend further west than is currently known. This species was previously recorded in two additional localities, "Kuzyuk-Kakty Pass" and near Arkatag village by the Przehevalski expedition in 1884 (Smith et al. 1990). The locality of Ikhe-Tsaidemin Nur requires confirmation (Smith et al. 1990). This species occurs at elevations of 4,200-4,800 m (Smith and Xie 2008).

Population [top]

Population:Ochotona koslowi was found to be locally abundant in a recent survey (Smith 2008). However, this species has been characterized as rare (Smith et al. 1990).
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species occupies alpine meadow tundra and digs holes in the swelling mounds of saline loess on the Guldsha Pass (Büchner 1894). The burrows constructed by this species are shallow (Smith et al. 1990). These pikas live communally at high densities (Smith and Xie 2008). Ochotona koslowi is characterized as general herbivore and is a diurnal species of pika (Smith et al. 1990). The total length of this species is 22.0-24.0 cm (Smith and Xie 2008). Only a single litter is produced each year (Zheng 1986), with four to eight young per litter (Smith and Xie 2008).

Threats [top]

Major Threat(s): It was speculated that Ochotona koslowi populations may have been negatively affected by vertebrate control programs in the region (Smith et al. 1990). Regional assessment in China indicated that this species is threatened by severely fragmented extent of occurrence and continuing decline in extent of occurrence, area of occupancy and area, extent and/or quality of habitat (Wang and Xie 2004).

Conservation Actions [top]

Conservation Actions: Research is needed in the areas of ecology, reproduction, population status, and distribution. Conservation measures should be drafted and implemented for this species (Smith 2008). This species was regionally assessed, in China, as Endangered under criteria B1ab(i,ii,iii) (Wang and Xie 2004). This species occurs in Aerjinshan Nature Reserve (CSIS 2008).
