|Scientific Name:||Uroplatus alluaudi|
|Species Authority:||Mocquard, 1894|
|Red List Category & Criteria:||Near Threatened ver 3.1|

Listed as Near Threatened on the basis that it has an extent of occurrence of 1,485 km², it occurs as a severely fragmented population, and further research may reveal that it is suffering a continuing decline in the extent and quality of its habitat that would require listing it as Endangered under criterion B1ab(iii).
This leaf-tailed gecko is endemic to northern Madagascar, where it is known from Montagne d'Ambre (Andreone and Aprea 2006), Binara at Daraina (Rakotondravony 2006), Besariaka (Glaw and Vences 2007) and Marojejy (Rakotomalala and Raselimanana 2003). It occurs between 650 and 950 m (Raxworthy and Nussbaum 1994), and has an estimated extent of occurrence of 1,485 km².

There is no quantitative information on the population of this species but it is regularly encountered in Montagne d'Ambre (Glaw and Vences 2007), where it appears to be localized in drier areas of the reserve. The known localities are widely separated, and the population is presumed to be severely fragmented.
|Habitat and Ecology:||This nocturnal lizard is found in mid-altitude humid forest; it is associated with patches of relatively dry vegetation in Montagne d'Ambre (Glaw and Vences 2007), but is known from the most humid forest in Daraina (Rakotondravony 2006). At least one specimen has been recorded from a banana plantation in Montagne d'Ambre, either outside the protected area or planted illegally within the reserve (F. Glaw pers. comm. May 2011), suggesting that the species exhibits some ability to persist in modified habitats. It has been observed at heights of two to three metres above the ground.|
|Major Threat(s):||Although this species occurs mostly within protected areas, it occurs close to degraded areas and within secondary forest, and it is likely to be affected by the loss and degradation of forest through cattle grazing, timber extraction and agriculture.|
|Conservation Actions:||This species occurs in three national parks. Further research is needed to clarify the distribution of and population densities in this species, and to establish whether threatening processes affect the habitats where this gecko occurs and its ability to tolerate disturbance.|
