Dicksonia stuebelii

Unknown

Overview

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

Dicksonia stuebelii faces severe population decline primarily due to habitat destruction from agricultural expansion and logging activities in its native cloud forest ecosystems. The species is particularly vulnerable to climate change impacts, as rising temperatures and altered precipitation patterns threaten the cool, humid conditions essential for tree fern survival. Collection pressure for the horticultural trade has further reduced wild populations, with mature specimens being harvested for their ornamental value.

Threat summary

Habitat

This tree fern species inhabits cool, humid cloud forests and montane rainforests at elevations between 1,500-2,500 meters. It requires consistently moist conditions with high humidity and filtered sunlight, typically growing in the understory of primary and secondary forests.
