Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2015
Date Assessed: 2015-07-21
Assessor(s): Fisher, R., Hamilton, A., Allison, A., Tallowin, O. & Oliver, P.
Reviewer(s): Cox, N.A. & Bowles, P.
Gehyra oceanica has been assessed as Least Concern in view of its wide distribution and presumed large overall population. It occurs in multiple protected areas and thrives in modified habitats. Further taxonomic research is recommended, and monitoring of populations in areas where it may be locally affected by invasive species is necessary.

Geographic Range [top]

Range Description:

Habitat and Ecology [top]

Habitat and Ecology:This is a nocturnal, arboreal gecko. It occurs in primary and secondary forested habitats and coastal thickets. It also occurs in edificarian habitats such as rural gardens and urban areas and many populations are commensal with humans (Buden 2007).

Use and Trade [top]

Use and Trade: There is no trade or use information for this species.

Threats [top]

Major Threat(s): It is unlikely that any major threats are impacting this species. The population of this species on Guam may be extirpated due to predation from the introduced Brown Tree Snake (Boiga irregularis) and may be threatening this species on other islands where the snake has been introduced, likewise house geckos (Hemidactylus frenatus) may also impact this species. On atolls, sea level rise is a real threat to this species.

Conservation Actions [top]

Conservation Actions: There are no specific conservation measures in place for this species. This species is likely to occur in multiple protected areas in New Guinea, Bismarck Archipelago, Admiralty islands and north Solomon islands. Further research into this species' taxonomy is required.
