Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii) ver 3.1
Year Published: 2011
Date Assessed: 2011-01-25
Assessor/s: Jenkins, R.K.B., Andreone, F., Andriamazava, A., Anjeriniaina, M., Glaw, F., Rabibisoa, N., Rakotomalala, D., Randrianantoandro, J.C., Randrianiriana, J., Randrianizahana , H., Ratsoavina, F. & Robsomanitrandrasana, E.
Reviewer/s: Bowles, P. & Tolley, K.
Justification:
Listed as Endangered as the species is known only from Ankarafantsika in the northwest, considered to represent a single location at risk from fire, its extent of occurrence is 1,300 km² and there is a continuing decline in the quality of the habitat due to cattle grazing, fire and charcoal collection.

Geographic Range [top]

Range Description: This species is restricted to the island of Madagascar where it is only known from Parc National d'Ankarafantsika in the northwest (Ramanamanjato and Rabibisoa 2002, Glaw and Vences 2007) below 200 m. Surveys elsewhere in western Madagascar have failed to record the species (Raselimanana 2008; J.C. Randrianantoandro pers. comm. Jan 2011). As suitable dry forest occurs throughout Ankarafantsika (R. Jenkins pers. comm. June 2011) the lizard's extent of occurrence is estimated to be 1,300 km², the area of the national park.

Population [top]

Population:

This species is locally abundant (Mori et al. 2006). Abundance and presence of this species varies between sites within Ankarafantsika (Carpenter and Robson 2005), but it is unclear whether its distribution within the park is continuous or fragmentary.

Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology:

This species lives in dry deciduous forest (Razafimahatratra et al. 2008). Clutch sizes of 2-5 eggs have been recorded. It is diurnal and roosts in low vegetation at night at a mean height of 0.17 m (Carpenter and Robson 2005). Most individuals roost on small plants but fallen logs, lianes and small trees are occasionally used (Razafimahatratra et al. 2008). Animals bask on the leaf litter (Razafimahatratra et al. 2008).

Systems: Terrestrial

Threats [top]

Major Threat(s): The major threats to the species include bush fires, cattle grazing, and deforestation for charcoal collection (Ramanamanjato and Rabibisoa 2002). Fire is widespread within the park boundary (R. Jenkins pers. comm. June 2011).

Conservation Actions [top]

Conservation Actions:

This species is protected under Malagasy law but collection from the wild is permitted with authorization. Collection from within Parc National d'Ankarafantsika is prohibited. The species' distribution within Ankarafantsika is uncertain, and more information is needed to establish this species' extent of occurrence, area of occupancy and population status. The reserve itself should be managed to limit the encroachment of human activities that may threaten this chameleon.
