Kingdom Phylum Class Order Family
ANIMALIA CHORDATA MAMMALIA EULIPOTYPHLA SORICIDAE

Scientific Name: Crocidura hikmiya
Species Authority: Meegaskumbura, Meegaskumbura, Pethiyagoda, Manamendra-Arachchi & Schneider, 2007

Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii) ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Meegaskumbura, S. & Meegaskumbura, M.
Reviewer(s): Amori, G. (Small Nonvolant Mammal Red List Authority) & Cox, N. (Global Mammal Assessment Team)
Justification:
Listed as Endangered because its extent of occurrence is less than 5,000 km² (currently known only from a maximum of 110 km²), all individuals are in a single location (Sinharaja Forest), and there is probably continuing decline in the extent and quality of its habitat.

Geographic Range [top]

Range Description: This recently described species is currently known only from the Sinharaja World Heritage Site, Sri Lanka (Meegaskumbura et al. 2007). It has been recorded at two sites in Sinharaja Forest, at Kudawa (460 m asl) and Morningside (1,040 m asl) (Meegaskumbura et al. 2007). Sampling efforts at ten other sites in Sri Lanka have not located any additional populations, and it seems possible that this species is restricted to Sinharaja Forest with an available range of 110 km²; although it is still considered possible that it might be present in other nearby forested areas (Meegaskumbura et al. 2007).

Population [top]

Population: It is considered to be the most abundant shrew species in Sinharaja (Meegaskumbura et al. 2007).
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: Meegaskumbura et al. (2007) only recorded the species from recent secondary forest (regrowth since logging operations in the 1970s), although it is possible that animals initially identified as Crocidura miya by Wijesinghe and Brooke (2005) from unlogged forest habitat at Sinharaja might be C. hikmiya (Meegaskumbura et al. 2007). The forest at Kudawa is as a MesuaDoona community (mixed dipterocarp forest), while the forest at Morningside is transitional between the lowland wet-evergreen vegetation and low-elevation (~1,000 m asl) tropical montane forest (Meegaskumbura et al. 2007).
Systems: Terrestrial

Threats [top]

Major Threat(s): It seems probable that the habitat of this species is under a degree of degradation or loss, largely through conversion of these forested areas to agricultural use (including plantation systems).

Conservation Actions [top]

Conservation Actions: This species is present in the Sinharaja World Heritage Site. Additional studies are needed into the distribution, natural history and threats to this species.
