Cyathea strigillosa

Unknown

Overview

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

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

Threat summary

Habitat

This tree fern inhabits humid montane forests and cloud forest environments, typically growing in shaded understory conditions with consistent moisture levels. It requires well-drained but permanently moist soils and thrives in the stable microclimatic conditions found in intact forest ecosystems.

Frequently asked questions

Why is Cyathea strigillosa classified as Critically Endangered?
Cyathea strigillosa 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 strigillosa faces severe population decline primarily due to deforestation and habitat conversion for agriculture and development in its limited range. The species' restricted distribution makes it particularly vulnerable to localized threats, with remaining populations fragmented across increasingly isolated forest patches. Climate change poses an additional threat through altered precipitation patterns and temperature shifts that affect the humid microhabitats essential for tree fern survival.
Where does Cyathea strigillosa live?
Cyathea strigillosa occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Cyathea strigillosa?
The main threats to Cyathea strigillosa 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.
