Scientific Name: Zonosaurus tsingy Raselimanana, Raxworthy & Nussbaum, 2000
Taxonomic Notes:

The population of Zonsaurus tsingy on the offshore island of Nosy Hara may represent a new species; as this form is so far known from only a single individual, further studies in this locality are needed to clarify this issue (Raselimanana et al. 2009).

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2011
Date Assessed: 2011-01-26
Assessor(s): Raxworthy, C.J. & Raselimanana, A.
Reviewer(s): Cox, N.A. & Bowles, P.
Listed as Least Concern because, although this species has a fairly restricted range (below 5,500 km²), it does not occur as a severely fragmented population and, although there may be some localized pressures in sites where this species is dependent on forest, there is no evidence of continuing decline in the extent and quality of its karst habitat.

Geographic Range [top]

Range Description:

This species is endemic to Madagascar where it is known from two mainland localities in the extreme north of the island, Ankarana and Montagne des Français, at around 100 m elevation (Raselimanana et al. 2000) and from the small off-shore island Nosy Hara (Metcalf et al. 2007). The lizard's estimated extent of occurrence is 5,459 km².

Habitat and Ecology [top]

Habitat and Ecology:

This terrestrial plated lizard is found in lowland dry, deciduous forest associated with karst outcrops, and also occurs in karst outside the forest. It is diurnally active and strongly associated with rock faces and crevices (Raselimanana et al. 2000), although juveniles occur in nearby leaf litter. On Nosy Hara islands its presence was significantly related to the availability of rocks and it was absent in sites with high ground vegetation cover (Metcalf et al. 2007). Conversely, in a survey of Montagne des Français all records of this species were from relatively undisturbed forest (D'Cruze and Kumar 2011).


Use and Trade [top]

Use and Trade:

There is no information to suggest that this species is traded or used.

Threats [top]

Major Threat(s): This species might be affected by the loss and degradation of low dry forest (through logging). While this is not thought to be a significant threat at present, it has been suggested that the lizard may be at high risk of local extinction in Montagne des Français, where it appears reliant on forest (D'Cruze and Kumar 2011).

Conservation Actions [top]

Conservation Actions: This species is found in Ankarana Special Reserve and conservation management is planned for Montagne des Français. The taxonomic status of the recently-discovered Nosy Hara subpopulation requires clarification, and further surveys are needed to establish the limits of this species' distribution, its reliance on forest habitats, and its ability to withstand the effects of logging.
