Oligodon sublineatus

Declining

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Oligodon sublineatus faces significant pressure from agricultural expansion and urban development across its limited range in Southeast Asia. Deforestation for palm oil plantations and rice cultivation has fragmented its forest habitat, while collection for the international pet trade has further reduced wild populations. Climate change poses an additional threat through altered precipitation patterns affecting the species' preferred microhabitats.

Threat summary

Habitat

This snake inhabits lowland tropical forests, forest edges, and secondary growth areas in Southeast Asia, typically found in leaf litter and under fallen logs. It shows preference for areas with dense ground cover and moderate moisture levels, often near forest streams or in bamboo groves.
