|Scientific Name:||Martes gwatkinsii|
|Species Authority:||Horsfield, 1851|
Martes flavigula subspecies gwatkinsii Horsfield, 1851
|Taxonomic Notes:||This species has been sometimes been included in Martes flavigula (Corbet 1978, Honacki et al. 1982, Corbet and Hill 1992), but has been separated as a valid taxon by other authors (Bonhote 1901; Pocock 1936, 1941; Ellerman and Morrison-Scott 1951; Anderson 1970; Rozhnov 1995). A revision of taxonomy is required (Wozencraft 2005).|
|Red List Category & Criteria:||Vulnerable B1ab(iii,iv) ver 3.1|
|Assessor(s):||Choudhury, A., Wozencraft, C., Muddapa, D. & Yonzon, P.|
|Reviewer(s):||Duckworth, J.W. (Small Carnivore Red List Authority) & Schipper, J. (Global Mammal Assessment Team)|
This species is listed as Vulnerable because its entire extent of occurrence is less than 20,000 km², its distribution is severely fragmented, and there is continuing decline in the extent and quality of its forest habitat in the six discontinuous national parks where is occurs. In addition, remaining populations are severely fragmented due to a continuing decline in the extent and quality of habitat.
|Range Description:||The nilgiri marten is endemic to the Western Ghats of India (Balakrishnan 2005). The species is habitat specific and localized within its distribution. This species has been recorded across a wide range of elevations from 300 to 1,400 m with an average of around 990 m for preferred habitat (Mudappa 1999; Balakrishnan 2005). Most of the records known for this species are from protected areas (Muddapa pers. comm.).|

|Population:||The population trend for the nilgiri marten is unknown, but it is thought to naturally occur at low densities, or indeed lower densities than the closely related yellow throated marten (Duckworth pers. comm.). This species was considered rare by Pocock (1941), but more recently was seen regularly (12 sightings) in Kalakad-Mundanthurai Tiger Reserve (KMTR) in India between May 1996 and December 1999 (Mudappa 2002).|
|Habitat and Ecology:||
The nilgiri marten has been reported from moist tropical rainforests (Mudappa 1999), montane evergreen forests (Yoganand and Kumar 1999), and moist deciduous forests adjoining wet evergreen forests (J. Joshua pers. comm.), as well as somealtered habitats such as coffee and cardamom plantations (Schreiber et al. 1989) and acacia plantations (Yoganand and Kumar 1999). The majority of sightings have come from areas with little canopy and sub-canopy cover, far from human paths and in relative proximity to water (Balakrishnan 2005).
This species is partly frugivorous and insectivorous (Balakrishnan 2005), but will prey opportunistically on almost any small bird or mammal (Pocock 1941), including Indian chevrotain and monitor lizards (Varanus bengalensis; Mudappa 1999), mouse deer (Moschiola memmina; Mudappa 2002), and it occasionally even feeds on nectar (Hutton, 1944).
|Major Threat(s):||The nilgiri marten is threatened by habitat loss and fragmentation throughout its area of occupancy. These threats, as well as hunting, are all detrimental to this species, especially in the lower altitudes of its range (Balakrishnan 2005).|
The nilgiri marten is listed in Schedule II part II of the Indian Wildlife (Protection) Act, 1972, and Appendix III of CITES (India).
This species occurs in several protected areas. Some of these include Rajamala Eravikulam National Park (Madhusudan 1995), Mukkurthi National Park (Yoganand and Kumar 1995, 1999), Peppara Wildlife Sanctuary and Silent Valley National Park (Christopher and Jayson 1996), Sholayar (Vijayan 1979), Upper Bhavani (Gokula and Ramachandran 1996), Brahmagiri (Schreiber et al. 1989), Kalakkadu-Mundanthurai Tiger Reserve (Mudappa, 2001), Periyar Tiger Reserve (Kurup and Joseph, 2001), and Chinnar Wildlife Sanctuary (Balakrishnan, 2005). It was also sighted in Silent Valley National Park, Attappadi Reserve Forest, Muthikkulam South Reserve Forest, and Nilambur South Reserve Forest by Balakrishnan (2005).
Schreiber et al. (1989) recommended field surveys to locate remaining populations and determine if existing reserves give adequate protection. Accordingly, a systematic survey has been conducted following the recommendation of the action plan. Although poaching incidents are not frequent in protected areas, measures to regulate hunting outside of these areas are ineffective, especially in lowland forests (Balakrishnan 2005). There is a need for more survey work, and more protected areas, especially in the lower altitudes of its range, and in particular the forests contiguous to Silent Valley National Park (Balakrishnan 2005).
