Conservation Actions

While there are no direct conservation measures for this species in place at present, most of Tioman was declared a 'state wildlife reserve' in 1972 (Ng et al. 1999). However, the island is not part of the protected area system (I. Das pers. comm. 2011). Further research into the abundance, habitat requirements, threats and ecology of this species is suggested, and population monitoring is recommended.
Twenty additional lizards and snakes are endemic to the same forest patch, making this a priority area for conservation in Malaysia (I. Das and G. Vogel pers. comm. 2011). Conservation measures should be undertaken, along with further research into trends in abundance and impact of altered habitat on this species. Due to the number of endemic species known to be present on the island, the distribution should be included within the national protected area system.

Location Information

This species is endemic to the Seribuat Archipelago in West Malaysia, where it is only known to occur on Tioman island (Grismer et al. 2006). The maximum extent of occurrence is the area of forest on the island, which is approximately 100 km².

Geographic Range



Population Information

Two specimens were recorded at 98 m. asl. in one pitfall trap (I. Das pers. comm. 2011). There are no additional population data available for this species. Due to the current rate of forest loss, which may result in the removal of all forest on the island within the next ten years (and therefore also within the longer of ten years or three generations), this species is likely to become extinct without preventative action to preserve its habitat.


The forests of Tioman are not protected and are currently subject to private management. The island is a well-known tourist destination and development for both residential and tourist areas is both ongoing and expanding, which is degrading and removing this species' forest habitat at a rate which may result in the complete loss of forest from the island within ten years.
