Indonesia · Island occurrence guide

Yapen

6 existing species accounts name this island or island group. This index shows the current sourced collection, not a complete island checklist.

Papua · Regional landscape

Place the record in context.

Lorentz National Park spans a remarkable gradient from the central cordillera toward the Arafura coast, connecting mountain environments with southern lowlands and wetlands.

This describes the wider region. Local vegetation and the habitat of an individual species require their own evidence.

The wider region

Papua

Indonesian New Guinea and nearby Indonesian islands. Papua New Guinea is outside this chapter; Aru is indexed under Maluku.

Landscape context

Read the habitats.

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

Behind the occurrence.

Choose an account recorded in Yapen. 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.
