Cycas javana

Declining

Overview

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

Cycas javana faces severe population decline primarily due to extensive habitat destruction from agricultural expansion and urban development across Java's lowland regions. The species is further threatened by overcollection for horticultural trade, as cycads are highly valued ornamental plants. Climate change compounds these pressures by altering rainfall patterns and increasing drought stress in remaining forest fragments.

Threat summary

Habitat

Cycas javana inhabits lowland tropical forests and forest margins across Java, typically growing in well-drained soils at elevations below 800 meters. The species occurs in both primary and secondary forest environments, often persisting in degraded forest patches and along forest edges.

Frequently asked questions

Why is Cycas javana classified as Critically Endangered?
Cycas javana 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. Cycas javana faces severe population decline primarily due to extensive habitat destruction from agricultural expansion and urban development across Java's lowland regions. The species is further threatened by overcollection for horticultural trade, as cycads are highly valued ornamental plants. Climate change compounds these pressures by altering rainfall patterns and increasing drought stress in remaining forest fragments.
Where does Cycas javana live?
Cycas javana 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 Cycas javana?
The main threats to Cycas javana are 5.3, ai-1, ai-2, and ai-3. The full IUCN-classified threat record for this species is detailed on the species page.
