28 existing species accounts name this island or island group. This index shows the current sourced collection, not a complete island checklist.
Sumatra · Regional landscape
Place the record in context.
The UNESCO rainforest property links Gunung Leuser, Kerinci Seblat and Bukit Barisan Selatan. These protected landscapes preserve lowland and mountain forest along Sumatra’s western spine.
This describes the wider region. Local vegetation and the habitat of an individual species require their own evidence.

Behind the occurrence.
Choose an account recorded in Belitung. Its country-level evidence retains the named islands and qualifications; it is not a record of a sighting at an exact map point.
The shared collection
Snakes recorded here.
Each card opens the same species account used by the country lists. A shared island record does not imply occurrence in all countries sharing that island.
