Distribution, Range

This species is endemic to Indonesia, where it is found only on Sulawesi and Buton Island off the southeast coast, with no records of either species of Anoas from other small neighbouring islands adjacent to Sulawesi (Burton et al. 2005). This species has been typically recorded from 1,000 to 2,300 m, but can be found at near sea level (National Research Council 1983, Sugiharta 1994, G. Semiadi pers. comm. 2006). It remains uncertain whether the two putative species, Bubalus depressicornis and Bubalus quarlesi, are sympatric or parapatric in their distribution (Burton et al. 2005). Across the island, local distribution of anoa species remains unclear, as they may occur in forest patches at different altitudes or sympatrically (Burton et al. 2005). Records of skulls and morphological descriptions of this species recently could only confirm that it was present across most of the Central region of Sulawesi and in the north of Buton Island (Burton et al. 2005). However, slightly earlier reports suggest the Mountain Anoa also occurs in the north peninsular and part way along the southeastern peninsular (Groves 1969). Both of these areas still sustain anoa populations, so these may include populations of Mountain Anoa. Identifying Mountain Anoa, and therefore their range, is made difficult by the fact that they cannot be differentiated from young Lowland Anoa. Historically, anoas of one species or other were present throughout the majority of the island's forests (Weber 1890, Sarasin and Sarasin 1901, Mohr 1921, Harper 1945, Groves 1969, Burton et al. 2005).

Justification

This species is considered Endangered because its population is estimated to be less than 2,500 mature individuals, its rate of decline is believed to be greater than 20% over two generations (14 to 18 years), and no subpopulation is believed to number more than 250 mature individuals.

Ecology Discription

Appearance

 

Habitat

There is very little is known about the ecology and life history of the Anoas (Burton et al. 2005). This species is typically found in dense forest as opposed to more open subalpine habitats, and prefers habitats with dense understory vegetation (Foead 1992, Sugiharta 1994, G. Semiadi pers. comm. 2006). Mountain Anoas typically live near abundant water sources in areas with low human activity (Sugiharta 1994), and in the past there are records at sea level.

IUCN

Population size

Too few data exist to precisely quantify the current abundance of Mountain Anoa. Nevertheless, they still appear to be distributed relatively widely within their known historical range on Sulawesi. However, there is little doubt that they have been in decline (i.e., there has been a decrease in their range and abundance) since the end of the 19th century. They have declined over the 1980 to 2000 period (ca. three generations), precipitously in some areas. The population size is unknown because there have been no island-wide surveys to estimate this, even for the largest populations. Estimating the population size is further complicated by the uncertain distribution of the two anoa species. It is thought that there are less than 2,500 mature individuals. There have been declines of this species throughout Sulawesi, especially in the southern and northeastern peninsulas, with the decline attributed to hunting for meat and habitat loss (Burton et al. 2005). Most populations are becoming rapidly fragmented, suggesting that conservation of viable populations may soon require management of metapopulations (Burton et al. 2005). It is thought no subpopulation exceeds 250 mature individuals. The current status of the species is consequently a matter for concern because even the subpopulations in large protected areas (e.g., Lore Lindu National Park) and other large forest blocks are reported to be in decline as a result of heavy hunting pressure. There are two areas where the declines have been most serious, Gorontalo and Buol Toli-Toli (G. Semiadi pers. comm. 2006). Overall, the decline rate is not well known, however, based on distribution surveys and questionnaires, the range of this species is retreating to the central parts of forested areas. The rate of population decline across their range is thought to be 20% over two generations (generation length of 7 to 9 years).

IUCN

Behavior

Like other wild buffalo, Anoas wallow and bathe in pools of water and/or mud. It is probable that mineral springs or licks are also required, although Anoa are reported to drink seawater, which might fulfil their mineral needs in areas without licks or springs. The species is solitary and is a browser, feeding on grasses and other vegetation (Whitten et al. 1987, Foead 1992). The typical life span in captivity is reported to be 20 to 30 years, with age at sexual maturity at 2 to 3 years old (in captivity), with typically one offspring per year (NRC 1983, Jahja 1987), though in wild conditions this may be less.

Threat

Major Threat(s)

The two major threats to this species are hunting, for food, and habitat degradation (Burton et al. 2005) due to agriculture, mining (gold mining) (G. Semiadi and D. Gunaryadi pers. comm. 2006). Illegal international trade in live animals or body parts is not thought to present a serious threat.

Conservation and Measurement

International

This species is listed in CITES under Appendix I, and fully protected under Indonesian law (Jahja 1987, Burton et al. 2005).

IUCN

National

This species is listed in CITES under Appendix I, and fully protected under Indonesian law (Jahja 1987, Burton et al. 2005). Mountain Anoa occur in a number of protected areas. There are several key protected areas thought to hold significant populations of this species, including Lore Lindu National Park, Bogani Nani-Wartabone National Park, and Tanjung Peropa Nature Reserve on Sulawesi (Burton et al. 2005). There is an on-going status survey, as well as genetic and morphological research that aims to clarify the confusion that surrounds anoa systematics. A small number of Mountain Anoa are in captivity, but the breeding program has been greatly hindered by the difficulties of assigning captive anoa to appropriate taxa. The captive population has around five individuals in a Mountain Anoa breed line (J. Burton pers. comm.), although the taxonomic status of most individuals remains uncertain (Notzold 1999).

IUCN

Other Coservation Projects

According to Burton et al. (2005) this species requires the following conservation actions: (1) protection from hunting, (2) prevention of habitat loss at key sites, (3) complete genetic studies to better determine the taxonomy of this species, and (4) determination of the status of remaining populations. Law enforcement combined with education should be employed to reduce hunting pressure.
