Although Oligodon sublineatus has a small distribution within a region that has high rates of habitat loss and degradation, this species can inhabit a variety of habitats, suggesting that it has more generalist habitat preferences. Therefore, a Least Concern category has been assigned. Monitoring of this species should be carried out because if threat levels increase, significant population declines may occur. Currently, however, O. sublineatus remains common in parts of its range..

Habitat and Ecology [top]

Habitat and Ecology:This terrestrial and diurnal species is known to occur in the wet zone of Sri Lanka, a mainly wet tropical forest region. It is known to shelter among debris, under stones and in cracks in the earth and loose soil (de Silva 2008). It has also been recently reported from Bundala National Park, an area of dry, thorny scrubland and dry forest, and from home gardens (IUCN 2002). It is frequently found in environments modified by humans, including plantations and houses (R. Somaweera pers. comm.).

Threats [top]

Major Threat(s): This species is likely to be experiencing the loss and fragmentation of its natural habitat. However, as this species is tolerant of environments affected by humans, these should not be considered major threats at this time. This species resembles venomous snakes of the region and is often killed when encountered by humans, so that persecution constitutes a major threat.

Conservation Actions [top]

Conservation Actions: There are no known species-specific conservation measures in place for this species at the present time. There are protected areas within its range.
