Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA MAMMALIA RODENTIA MURIDAE

Scientific Name: Niviventer hinpoon
Species Authority: (J.T. Marshall Jr., 1976)
Common Name(s):
English Limestone Niviventer, Limestone Rat

Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Aplin, K. & Lunde, D.
Reviewer(s): Amori, G. (Small Nonvolant Mammal Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
Justification:
Listed as Data Deficient as the limits of distribution of this species are not well known, and there is no information on its current population status. It is likely confined to the Korat Plateau, although a large tract of habitat is protected within the Khao Yai National Park (where the species may occur, but has not yet been recorded). With further survey work, this species likely will warrant listing in a threatened category, either as Vulnerable under criterion D2 or, if not present in Khao Yai, in Endangered based on its restricted range and a concomitant decline of habitat.

Geographic Range [top]

Range Description: This species is currently known only from the Korat Plateau in south east Thailand (Musser and Carleton 2005). It is likely to be confined to this karst area of Thailand, but is currently known only around the immediate vicinity of the type locality.

Native:
Thailand

Population [top]

Population: It is patchily distributed, being tied to karst habitats, but there is no current information on population status.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: This species is closely associated with limestone cliff habitat. It was collected halfway up the face of a forested limestone cliff outside the entrance to a cave, while another record is from "high above the valley floor, in scrubby vegetation at the base of vertical limestone cliffs" (Lekagul and McNeely 1988).
Systems: Terrestrial

Threats [top]

Major Threat(s): The major threat is likely to be habitat loss and degradation, particularly of the limestone forest, although it may be shown to occur in the nearby Khao Yai National Park where there is improved habitat protection.

Conservation Actions [top]

Conservation Actions: It may occur in Khao Yai National Park, but as far as is known it has not yet been recorded. This species is in need of further survey work to establish whether it really is endemic to, and more widespread on, the Korat Plateau.
