Cyathea microdonta

Unknown

Overview

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

Cyathea microdonta faces severe population decline primarily due to deforestation and habitat conversion for agriculture in its limited montane forest range. The species' restricted distribution makes it particularly vulnerable to localized threats, with logging activities and human encroachment fragmenting the remaining suitable habitat. Climate change poses an additional threat by altering the specific temperature and humidity conditions required by this tree fern in its high-elevation ecosystem.

Threat summary

Habitat

Cyathea microdonta inhabits montane cloud forests and humid tropical forests at elevations typically between 1,000-2,500 meters. This tree fern requires consistently moist conditions with high humidity and filtered sunlight, thriving in the understory of primary and secondary forests with rich, well-drained soils.

Frequently asked questions

Why is Cyathea microdonta classified as Critically Endangered?
Cyathea microdonta 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 microdonta faces severe population decline primarily due to deforestation and habitat conversion for agriculture in its limited montane forest range. The species' restricted distribution makes it particularly vulnerable to localized threats, with logging activities and human encroachment fragmenting the remaining suitable habitat. Climate change poses an additional threat by altering the specific temperature and humidity conditions required by this tree fern in its high-elevation ecosystem.
