Scientific Name: Uroplatus guentheri Mocquard, 1908

Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii) ver 3.1
Year Published: 2011
Date Assessed: 2011-01-28
Assessor(s): Raxworthy, C.J., Rabibisoa, N. & Bora, P.
Reviewer(s): Cox, N.A. & Bowles, P.
Listed as Endangered on the basis that it has an extent of occurrence of 3,554 km², it occurs as a severely fragmented population, and there is a continuing decline in the extent and quality of its habitat.

Geographic Range [top]

Range Description:This leaf-tailed gecko is endemic to Madagascar, where it has been recorded from scattered localities in the west of the island, at Ankarafantsika (Greenbaum et al. 2007, Ramanamanjato and Rabibisoa 2002, Raselimanana 2008), Andranomanintsy, Ambalimby/Masoarivo, Bemaraha and Kirindy (Raselimanana 2008), and Ankilogoa and Ranotsara  (Bora et al. 2010). It has been found at elevations between 30 and 120 m (Raselimanana 2008). The extent of occurrence, based on the area of known sites, is estimated to be 3,554 km².

Population [top]


This forest-dependent species is likely to be declining, but there is no quantitative population information. It occurs at low densities at known sites. Recorded localities are widely-separated, and dry deciduous forest occurs as isolated patches in western Madagascar, so the population is considered to be severely fragmented.

Current Population Trend:Decreasing
Additional data:
Population severely fragmented:Yes

Habitat and Ecology [top]

Habitat and Ecology:

This nocturnal lizard lives in intact dry deciduous forest. It has been observed roosting and foraging on bushes and low trees at height of between one and six metres. It lays spherical eggs in leaf-litter.

Continuing decline in area, extent and/or quality of habitat:Yes

Use and Trade [top]

Use and Trade: This species is exported annually from Madagascar for the international pet trade. The export quota in 2010 was 125 individuals, and it is likely that this will continue or stricter controls will be imposed.

Threats [top]

Major Threat(s): The intact forest on which this species depends is threatened by fires, cattle grazing, selective logging and charcoal production, and forest clearance for agriculture.

Conservation Actions [top]

Conservation Actions: This species occurs in Bemaraha and Ankarafantsika national parks. More information is needed on the population status of this gecko and the extent of its exposure to threats at known localities.
