Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA MAMMALIA PRIMATES INDRIIDAE

Scientific Name: Propithecus diadema
Species Authority: Bennett, 1832
Common Name/s:
English Diademed Sifaka
French Propithèque À Diadème
Synonym/s:
Propithecus diadema (Bennett, 1832) subspecies diadema
Taxonomic Notes: In the forests of Tsinjoarivo in south-central Madagascar, an unusual population of what appears to be P. diadema has been discovered. The animals are variably colored, including all black individuals, but preliminary genetic studies indicate that this population requires further study before subspecific status can be established (Mayor et al. 2004).

Assessment Information [top]

Red List Category & Criteria: Endangered A2cd ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor/s: Andrainarivo, C., Andriaholinirina, V.N., Feistner, A., Felix, T., Ganzhorn, J., Garbutt, N., Golden, C., Konstant, B., Louis Jr., E., Meyers, D., Mittermeier, R.A., Perieras, A., Princee, F., Rabarivola, J.C., Rakotosamimanana, B., Rasamimanana, H., Ratsimbazafy, J., Raveloarinoro, G., Razafimanantsoa, A., Rumpler, Y., Schwitzer, C., Thalmann, U., Wilmé, L. & Wright, P.
Reviewer/s: Mittermeier, R.A. & Rylands, A.B. (Primate Red List Authority)
Justification:
Listed as Endangered as the species 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 due to levels of exploitation.
History:
2000 Critically Endangered
1996 Endangered
1990 Endangered (IUCN 1990)

Geographic Range [top]

Range Description: This species occurs throughout eastern Madagascar from about the Mangoro and Onive Rivers north to the Mananara Nord River. Its occurrence between Antainambalana River near Maroantsetra and Mananara Nord River, as reported by earlier authors (e.g., Petter et al. 1977) has not been confirmed in recent years. At the southern limit of its range there seems to be a clinal gradient between P. diadema and P. edwardsi (Andriaholinirina and Rabarivola 2004). Ranges from 200-1,625 m.

Population [top]

Population: Rare. It occurs only at very low densities wherever it is found.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It is found in the eastern rainforests, and persists in smaller forest fragments. There have been no long-term field studies of the Diademed Sifaka. However, it is known to be diurnal and to live in multi-male/multi-female groups of up to eight or more individuals that defend home ranges of 20 - 50 ha by means of scent-marking (Mittermeier et al. 2008; and references therein).
Systems: Terrestrial

Threats [top]

Major Threat(s): Continued destruction of rain forest habitat in eastern Madagascar due to slash-and-burn agricultural practices and timber extraction is the principal threat to this sifaka’s survival, although hunting for food also can have a very serious impact on remaining populations, even within existing protected areas (Mittermeier et al. 2008). Furthermore, illegal rum production, necessitating the planting of sugar cane fields, is a threat to populations in Tsinjoarivo (Irwin and Ravelomanantsoa 2004).

Conservation Actions [top]

Conservation Actions: This species is listed on Appendix I of CITES. This species occurs in three national parks (Mananara-Nord, Mantadia, and Zahamena), two strict nature reserves (Betampona and Zahamena), and three special reserves (Ambatovaky, Mangerivola, and Marotandrano) (Mittermeier et al. 2008). Additional populations have been identified in the Andriantantely Classified Forest, Tsinjoarivo Classified Forest, the Marokitay Forest Reserve, and in the unprotected forests of Anosibe an’ala, Anjozorobe, Didy, Iofa, Maromiza and Sandranantitra (Mittermeier et al. 2008). The Tsinjoarivo Classified Forest has already been recommended as a new protected area. As of 2007 this species was represented in only a single zoological collection at the Duke University Primate Center in Durham, North Carolina, USA.
