Overview

Distribution

Range Description

The species is distributed from the Mahavavy River to the south-west (separating it from P. deckenii) and the Betsiboka River to the north-east (separating it from P. coquereli). Petter et al. (1977) subsequently pointed out that hybridization between P. coronatus and P. deckenii probably occurred along the upper reaches of the Mahavavy River. Collections made in the forests of Ambararatabe (to the west of the Mahavavy River) and sightings along the Bongolava Massif (west of Tsiroanomandidy) also appear to include individuals of P. coronatus. Also, reliable reports of Crowned Sifakas as far south as the Sakay River, as far east as Andanotongo, and south-east beyond Tsiroanomandidy suggest that the distribution of this species is more complicated than originally believed (Tattersall 1986). Sea level to 700 m.

Justification
Listed as Endangered as although the range of this species is not well known, it is thought to have undergone a reduction of more than 50% over the past 30 years (assuming a generation length of 10 years) due primarily to a decline in area and quality of habitat within the known range of the species, and also due to the effects of hunting.

Threats

Major Threats
The main threat to this species is habitat loss, as forests within this species’ range have been lost to provide pasture for livestock and to produce charcoal. In some parts of the range they may be hunted, and captured for the pet trade.

Management

Conservation Actions

Conservation Actions
This species is included on Appendix I of CITES. There are reports of its occurrence in two special reserves (Ambohijanahary and Kasijy), although the status of populations in these protected areas is questionable. Efforts should be made to secure protection for populations at Katsepy and Anjamena that have been the subject of brief studies and are also visited by tourists. In addition, there is a need for further survey of a few classified forests within the crowned sifaka’s possible range that may also harbor viable populations (Mittermeier et al. 2008). A project called Antrema is conserving coastal forest around Katsepy. There is a European captive breeding programme, with very few founders, but apparently showing some success (C. Schwitzer pers. comm.).

Crowned sifaka

The crowned sifaka (Propithecus coronatus) is a sifaka endemic to Madagascar. It has a length of 87 to 102 centimeters, of which 47-57 centimeters are tail.[3] The crowned sifaka lives in western Madagascar.[3] It lives in dry deciduous forest.[3]

Its pelage is mostly creamy white, with head, neck and throat dark brown.[3] Group size is between 2 and 8 individuals.[3]
