Overview

Distribution

Range Description

The collared mongoose is found on the islands of Borneo (Malaysia: states of Sarawak and Sabah [Wells et al. 2005; Wong Siew Te pers. comm., J. Hon, pers. obs.]), Indonesia [van Strien 2001] and presumably Brunei, although no records have been traced) and on Sumatra (Indonesia Robinson and Kloss, 1919). The range on Borneo is much more extensive than depicted in Corbet and Hill (1992), with records from the Balikpapan area, Gunung Palung, and Kutai and museum records from Balikpapan, Kendawangan, Pontianak, and Sanggau (see van Strien 2001). In Sumatra, there are only two confirmed historical locality records; two individuals (including the holotype of H. s. uniformis) from Ayer Taman in Ophir District in W. Sumatra (300 m) adjacent to Gunung Paseman (Robinson and Kloss, 1919). The southern record from Jentink (1894) mentions one specimen from Soekadana, South Sumatra. No recent records have been traced from Sumatra.

Habitat and Ecology

Habitat and Ecology
The ecology of the collared mongoose remains to be studied. Payne et al. (1985) states that this species occurs in a number of different habitats, including primary forest, disturbed habitat, lowlands and hills, and in both disturbed and primary habitat. The species has been recorded from primary lowland rainforest by Wells et al. (2005), and Robinson and Kloss (1919) record this species in Borneo as occurring at 4000 feet Mt. Dulit. Further studies into distribution, suitable habitat types, tolerance to habitat conversion and general life history are required.

Justification
This species is listed as Data Deficient in view of the absence of recent information on its status and ecological requirements. Very little is known about this species, and therefore it requires more survey work. More specifically there is no information available on its adaptability to plantations or degraded forest, its upper altitudinal range limit is unclear (hence it could turn out to be very threatened by current forest conversion in the Sunda), and it is suspected to be threatened, however, to what extent is not currently understood. In addition, it is often not found in forests areas where is has been presumed to occur. It is unknown whether its rarity is natural, or due to human threats and therefore this species cannot be assessed against the categories and criteria until further information becomes available. This species is a priority for future research.

Population

Population
The population status of the collared mongoose is not known. Wong Siew Te (pers. comm.) suggests that this species is not common. Robinson and Kloss (1919) state that this species was rare in historical collections. Wong Siew Te (in litt. to J. W. Duckworth) only has camera trapped it once in Sabah over the last few years and suggests that this species is not common. Only two confirmed camera trap photos in Upper Baram in Sarawak (Jason Hon pers. comm.), which represents 30% of all mongoose photos both identified and unidentified. However, camera traps may not be a good indicator to show whether this species is common or rare as the chances of it passing the sensor without being detected are high (Azlan pers. comm.).

Threats

Major Threats
Forest conversion is taking place at very high rates in lowland Borneo and Sumatra (Shreiber et al. 1989). The effects of this on the collared mongoose are unknown because (i) it’s adaptability to secondary habitat is unclear and (ii) its extension into upland zones where forest conversion is currently lower is unclear. A number of people studying mammals in some of the best Bornean and Sumatran forests have not come across the species, suggesting a localised occupancy even of primary habitat. The causes for this are totally unknown.

Management

Conservation Actions

Conservation Actions
The collared mongoose is protected in all of Malaysia. While previously listed by Schreiber et al. (1989) as not definitely recorded from any protected area and never kept in a zoological garden, this species was recorded from a protected area, Mount Kinabulu National Park in Borneo, in 2003-04 (Wells et al. 2005). Schreiber et al. (1989) recommends field surveys to define more accurately the current status of the Sumatran collared mongoose, and to assess its conservation requirements. Urgent field surveys, field research and assessments of any possible threats are needed.
