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.

The wider region

Sumatra

Sumatra and associated offshore islands, including Bangka–Belitung, Riau and Natuna.

These guides describe documented environments in the wider Sumatra region. They do not assign every listed species to every habitat or protected site.
