Phelsuma andamanense has been assessed as Least Concern due to its ability to tolerate anthropogenic environments. However, as this species has a small range, monitoring of the population is still recommended to identify any potential declines.

Geographic Range [top]

Range Description:This species inhabits the Andaman and Nicobar islands which have a total land area of 8,120 km².
Countries occurrence:
India (Andaman Is., Nicobar Is.)

Population [top]

Population:Sharma (2002) states that the overall population status of this species is undetermined, but it is common in many localities.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species is able to inhabit highly modified environments. It has been recorded in gardens containing smooth palms and plantain trees, as well as in and around human habitation (Whitaker and Whitaker 1978, Sharma 2002, Daniel 2002). It has also been found in peepal, papaya, and occasionally exotic street trees (Whitaker and Whitaker 1978).

Threats [top]

Major Threat(s): The Nicobar and Andaman Islands have been and continue to be deforested, leading to extensive grasslands in certain areas (Khatri 1993). The main drivers are clearance for cash crops and monoculture plantations. The Andaman and Nicobar islands were also hit by the Asian Tsunami of 2004. The effect of the influx of salt-water and wreckage into the interior of islands is yet to be assessed (BirdLife International 2006).

Conservation Actions [top]

Conservation Actions: There are no known species-specific conservation measures in place for this species. There are a number of protected areas in the Andaman and Nicobar islands, but this network is still considered inadequate for the effective conservation of the endemics to the region (BirdLife International 2006). As a result, population monitoring is recommended.
