Cleistanthus robustus

Unknown

Overview

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

Cleistanthus robustus faces severe population decline primarily due to extensive deforestation and habitat conversion for agricultural expansion across its limited range in the Western Ghats. The species' restricted distribution makes it particularly vulnerable to localized threats, with remaining populations fragmented by human settlements and infrastructure development. Mining activities and quarrying operations in the region have further degraded critical habitat areas where this endemic tree species occurs.

Threat summary

Habitat

This endemic tree species occurs in the tropical evergreen and semi-evergreen forests of the Western Ghats biodiversity hotspot in India. It typically grows in moist, well-drained soils at elevations between 200-800 meters, often found along forest edges and in secondary growth areas within its highly restricted range.

Frequently asked questions

Why is Cleistanthus robustus classified as Critically Endangered?
Cleistanthus robustus 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. Cleistanthus robustus faces severe population decline primarily due to extensive deforestation and habitat conversion for agricultural expansion across its limited range in the Western Ghats. The species' restricted distribution makes it particularly vulnerable to localized threats, with remaining populations fragmented by human settlements and infrastructure development. Mining activities and quarrying operations in the region have further degraded critical habitat areas where this endemic tree species occurs.
Where does Cleistanthus robustus live?
Cleistanthus robustus occurs in Laos, Sri Lanka, and Vietnam. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Cleistanthus robustus?
The main threats to Cleistanthus robustus are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
