Cyathea varians

Unknown

Overview

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

Cyathea varians faces severe population decline primarily due to deforestation and habitat conversion for agriculture and urban development across its limited range. The species' restricted distribution makes it particularly vulnerable to localized threats, with remaining populations fragmented and isolated. Climate change poses an additional threat through altered precipitation patterns and temperature shifts that affect the humid conditions essential for tree fern survival.

Threat summary

Habitat

This tree fern inhabits humid montane forests and cloud forests, typically growing in shaded understory conditions with consistent moisture levels. It requires well-drained but permanently moist soils and is often found along stream banks and in forest ravines where humidity remains high year-round.

Frequently asked questions

Why is Cyathea varians classified as Critically Endangered?
Cyathea varians 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. Cyathea varians faces severe population decline primarily due to deforestation and habitat conversion for agriculture and urban development across its limited range. The species' restricted distribution makes it particularly vulnerable to localized threats, with remaining populations fragmented and isolated. Climate change poses an additional threat through altered precipitation patterns and temperature shifts that affect the humid conditions essential for tree fern survival.
Where does Cyathea varians live?
