Assessment Information [top]

Red List Category & Criteria: Vulnerable A3c ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Supriatna, J.
Reviewer(s): Mittermeier, R.A. & Rylands, A.B. (Primate Red List Authority)
This species is considered Vulnerable due to a continued decline estimated to be more than 30% over the next 40 years (3 generations), as a result of a projected increase in oil palm, cacao and cotton plantations and human settlement.

Geographic Range [top]

Range Description:This species is found on Sulawesi, Indonesia, and on the adjacent islands of Muna and Butung; it possibly occurs on the islet of Palau Labuan Blanda, as well.

Macaca ochreata ochreata
Occurs on Sulawesi. Found on the whole of the southeastern peninsula, extending to the north of the lakes region. In the east, the border between M. o. ochreata and M. tonkeana is the La River; in the west, M. o. ochreata extends west along the coast, across the Karaena River in its lower course, but does not reach into the uplands further inland (Groves 2001).

Macaca ochreata brunnescens
Occurs on Muna, Butung, and possibly the neighbouring islet of Palau Labuan Blanda (Groves 2001).

Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species is found in rainforests at moderate elevations, up to 800 m. It is frugivorous, but will eat immature leaves, arthropods, stalks of newly flowering plants, and cultivated crops (fruits, vegetables, and maize).

Threats [top]

Major Threat(s): There is extensive habitat loss within its range. Shifting cultivation by local communities is an increasing threat, as are oil palm and cacao plantations, as well as cotton cultivation, are displacing the natural habitat. Expanding human settlements are also a problem. There is extensive illegal "small scale" open area gold mining, using mercury, within protected areas. All of these factors are combining to increase the rate of habitat loss. Animals are also poisoned for crop raiding.
