Cassine koordersii

Declining

Overview

Cassine koordersii is a species of plant in the family Celastraceae. It is endemic to Java in Indonesia. It is a critically endangered species threatened by habitat loss.

Cassine koordersii faces severe population decline primarily due to extensive deforestation and habitat conversion across its native range in Southeast Asia. The species' restricted distribution makes it particularly vulnerable to localized habitat destruction from agricultural expansion and urban development. Mining activities and logging operations have further fragmented the remaining forest patches where this species occurs.

Threat summary

Habitat

Why is Cassine koordersii classified as Critically Endangered?
Cassine koordersii is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Cassine koordersii faces severe population decline primarily due to extensive deforestation and habitat conversion across its native range in Southeast Asia. The species' restricted distribution makes it particularly vulnerable to localized habitat destruction from agricultural expansion and urban development. Mining activities and logging operations have further fragmented the remaining forest patches where this species occurs.
Where does Cassine koordersii live?
Cassine koordersii occurs in Indonesia. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Cassine koordersii?
The main threats to Cassine koordersii are 2.2, 5.3, ai-1, and ai-2. The full IUCN-classified threat record for this species is detailed on the species page.
