Ecology

Habitat

Habitat and Ecology

Habitat and Ecology
This species has been recorded in primary forest (both evergreen and deciduous), secondary forest and plantations (Duckworth et al. 1997; Azlan, 2003) and is often said to have even wider habitat use (e.g. Lekagul and McNeely 1977). It has been recorded up to 1,600 m (Than Zaw et al. in press). It is solitary, nocturnal although there are occasinal day-time records of active animals (e.g. Than Zaw et al. in press) and it is usually active on the ground (Lekagul and McNeely, 1977, Duckworth 1997). An adult male was radio-tracked in Thailand and had a home-range of 12 km² (Rabinowitz, 1991). Occupancy of suitable habitats varies within Indochina.

Its diet consists of a wide range of animals, including fish, birds, lizards, frogs, insects, scorpions (and other arthropods) and crabs, as well as poultry and garbage (Lekagul and McNeely 1977).

In Lao PDR, this species is found in tall forest, both evergreen and deciduous, and adjacent degraded areas, over at least 200 to 1000 m, with few recent records from below 400 m (Duckworth et al. 1999); however, there are many records from other countries, e.g. Myanmar, below this altitude (Than Zaw et al. in press). They are believed to breed throughout the year, with two litters per year, and two to four young per litter (Lekagul and McNeely 1977). Breeding and resting dens are usually holes in the ground which were originally dug by other species. It was recorded in secondary forest, that was logged in the 1970s, and which surrounds a palm estate, in Malaysia in 2000-01 by Azlan (2003).

Like Viverricula and Civettictis, but to a generally much lesser extent, this civet has been used as a source of civetone, an oil-like substance secreted by the perineal gland used by the animal for territorial marking.

Reproduction

Reproduction

Females are polyestrous, breeding throughout the year. They have two litters per year and each litter can have up to four young. They are born in a hole in the ground or in very dense vegetation. Young can open their eyes in ten days and begin being weaned at one month of age. Weight at birth is less than 100g and doubles in 12 days. At the end of one month, the birth weight has increased four fold. The females raise the young on their own.

Average number of offspring: 3.

Justification
This species is listed as Near Threatened through circumstantial evidence of trapping-driven declines in heavily hunted and fragmented areas (notably China) and even within some large tracts of little-encroached habitat and the known heavy trade in the species as wild meat. Throughout most if its range non-selective snaring and other forms of trapping, hunting with dogs and projectile hunting are at very high levels. As a ground-dwelling species it is therefore exposed to heavy trapping pressure in much of its range. It remains widely distributed, retains large populations over much of its range, occurs in many protected areas, tolerates some degree of habitat modification (perhaps a lot more than is generally apparent today, given that the most degraded areas are among the most heavily hunted), and it is unlikely to be declining at nearly the rate required to qualify for listing as Vulnerable under criterion A. Currently, region-wide habitat conversion pressures are sufficiently high in the level lowlands to threaten ground-dwelling civets (e.g. Large-spotted Civet), but Large Indian Civet has a wide altitudinal range, with large populations in the hills and mountains. Therefore habitat loss and fragmentation rates are not sufficient to drive densities declines sufficient for listing as Vulnerable. Because it is such a widespread species, it is difficult to determine the population trajectory across its entire range. The overall population decline rate past, present and future is difficult to judge but it is unlikely that it exceeds 30% in three generations, i.e. sufficient to list this species as ‘Vulnerable’. This species could become Vulnerable if habitat conversion (particularly for rubber plantations in hill areas of northern South-east Asia) and fragmentation continues at current rates, and if regional demand for civet meat in luxury restaurants, particularly in China and Viet Nam, remains high and the international trade remains effectively unconstrained.

Population

Population
This species lives at a naturally fairly high density for a carnivorous animal and was almost universally considered common by historical collectors (Pocock 1939). It remains common in much of its range: it is possible to see several in a single night of spotlighting on foot even in heavily-hunted Lao PDR ( Duckworth 1997), it is among the most common mammals camera-trapped across Cambodia (J. L. Walmart pers. comm.) and Myanmar (Than Zaw et al. in press), and is one of the most commonly recorded civets in Viet Nam (Roberton et al. in prep.). However, in some areas (such as Southeastern China) it has become effectively extinct over large areas (M. W. N. Lau pers. comm.). Few other parts of the range are as severely impacted by habitat fragmentation and degradation coupled with hunting. It is likely that populations are widely reduced in the most heavily hunted parts of its range where habitat has been heavily fragmented, e.g. much of northern Viet Nam and lowland Lao PDR. Recent camera-trapping in the Nakai–Nam Theun national protected areas, Central Lao PDR, found rather few animals (Johnson and Johnston 2007), suggesting the possibility for very heavy ground-level trapping (as occurs in much of this area) to reduce populations greatly even in large tracts of little-encroached forest.

Threats

Threats

Major Threats
Habitat loss and degradation are a threat to this species (Schreiber et al., 1989). Across its range, there has been loss and degradation of forests through logging and conversion of forests to non-forest land-uses. It is hunted for food, probably throughout its range, and certainly in Viet Nam, China, Lao PDR, Myanmar, NE India and Thailand, and for scent glands in Viet Nam and China. Ground-living small carnivores are exposed to high levels of non-specific hunting, particularly with snares, throughout most of South-east Asia. Dogs are widely likely to be a problem for this ground-dwelling species, even though it is largely within burrows by day. Snaring and other forms of ground-level trapping occur in much of its range, including Lao PDR (Duckworth et al. 1997), Viet Nam, and Thailand, with trapping found both inside and outside protected areas (Kanchanasaka, pers. comm.). There has been an increased demand for civet meat in Chinese and Viet Namese markets (Bell et al. 2004; Lynam et al. 2005).

Large Indian civet

The large Indian civet (Viverra zibetha) is a member of the Viverrid family native to Southeast Asia. In 2008, the IUCN classified the species as Near Threatened, mainly because of trapping-driven declines in heavily hunted and fragmented areas, and the heavy trade as wild meat.[1]

Contents

Characteristics

Large Indian civets are generally grizzled greyish brown, with white and black bars along their neck, usually two white stripes and three black stripes on the tail, and a white muzzle. The hair on their back is longer. Their claws are retractable. They have hair in between their paw pads. This a large vivverid, measuring behind only the binturong and the African civet in size. The head-and-body length can range from 50 to 95 cm (20 to 37 in), the tail measuring 38 to 59 cm (15 to 23 in) and the hindfoot measuring 9 to 14.5 cm (3.5 to 5.7 in) long. Weight ranges from 3.4 to 9.2 kg (7.5 to 20 lb).[2][3]

Distribution and habitat

The large Indian civet ranges from Nepal, northeast India, Bhutan to Myanmar, Thailand, the Malay peninsula and Singapore to Cambodia, Laos, Vietnam and China.[1]

Subspecies

Viverra zibetha from Hodgson's drawings
Skull

Five subspecies are recognized:[4]

Six subspecies have been proposed but a taxonomic revision is needed. The validity of the new species Viverra tainguensis described in 1997 by Sokolov, Rozhnov and Pham Chong from Tainguen Plateau in Gialai Province in Vietnam has been seriously questioned, and it is now generally considered a synonym of V. zibetha.[1] Today research DNA confirm that be comprises the schedule of genes Viverra zibetha picta subspecies.

Ecology and behaviour

Diet

Large Indian civets are mostly carnivorous. They eat birds, frogs, snakes, small mammals, eggs, crabs, and fish, but also fruit and roots.

Social behavior

Large Indian civets are solitary and nocturnal. They spend most of their time on the ground, though they are agile climbers. During the day, they sleep in burrows in the ground that have been dug by other animals and abandoned. They are territorial and mark their territories with excretions from their anal glands. Their territory can range from 1.7 to 5.4 km2 (0.66 to 2.1 sq mi).

Reproduction

Females breed at any time of the year, and generally have two litters a year. A litter usually consists of four young. They are born in a hole in the ground or in dense vegetation. They open their eyes at 10 days and are weaned at one month of age.

Conservation

Viverra zibetha is totally protected in Malaysia under the Wildlife Protection Act of 1972 and listed on Category II of the China Wildlife Protection Law. China listed it as ‘Endangered’ under criteria A2acd, and it is a class II protected State species (due to trapping for food and scent glands). It is protected in Thailand, Vietnam and Myanmar. It is found in several protected areas throughout its range. The population of India is listed on CITES Appendix III.[1]

In Hong Kong, it is a protected species under Wild Animals Protection Ordinance Cap 170.

Local names

In Assamese it is called Gendera.

In Bengali it is called Bham or Bham Biral and Gandho Gokul or Khatas. Biral= cat, Gandho= smell or scent. Gokul= the place of Lord Krishna (Govinda) . In Bengal there is a delicate variety of sweet and pleasant smelling rice known as Govindabhog rice (the rice which is offered to Lord Govinda). The secretion from prene gland of civet cat smells like that variety of rice, so it is often called as "Gandho Gokul".
