Gigante Narrow-disked Gecko

Assessment Information [top]

Red List Category & Criteria:	Vulnerable D2 ver 3.1
Year Published:	2009
Assessor/s:	Diesmos, A., Brown, R., Gonzalez, J.C. & Paguntalan, L.M.
Reviewer/s:	Cox, N. & Hoffmann, M. (Global Reptile Assessment Coordinating Team)
Justification: Listed as Vulnerable because it is known from fewer than five locations, and there is a plausible threat that an increase in phosphate mining activities could negatively impact populations of this species.

Geographic Range [top]

Range Description:	This species is endemic to South Gigante Island and North Gigante Island, and nearby islets, located off of the northeast of Panay Island in the Philippines. It is found from sea level to around 200 m asl.
Countries:	Native: Philippines

Population [top]

Population:	In general, this is a very common species within its restricted distribution.
Population Trend:	Stable

Habitat and Ecology [top]

Habitat and Ecology:	Animals are found throughout much of the rocky limestone islands, and may be encountered in caves, in rock crevices, in the islands karst forest and on rocky coastal cliffs.
Systems:	Terrestrial

Threats [top]

Major Threat(s):	There is some phosphate mining within one of the caves that this species has been recorded within, and it seems possible that this disturbance may be a localized threat to the species. The islands are regularly visited by fishermen from the nearby fishing grounds, although the impact of this on the species is not known. Possibly the most significant threat would be extensive of mining for phosphate on the island, however, this is not taking place at present and there are no known plans to further develop mines on the islands.

Conservation Actions [top]

Conservation Actions:	In general, no conservation measures are currently needed for the species as a whole. There is a need to occasionally monitor the population of this lizard and the possibility of mining development on the islands.
