Cyathea kalbreyeri

Unknown

Overview

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

Cyathea kalbreyeri faces severe pressure from deforestation and agricultural expansion throughout its Andean range, with cloud forest habitats being converted for cattle ranching and crop cultivation. The species' restricted altitudinal range makes it particularly vulnerable to climate change, as warming temperatures force suitable habitat upslope into increasingly fragmented areas. Illegal collection for the horticultural trade has also impacted remaining populations, as tree ferns are prized for ornamental use.

Threat summary

Habitat

Cyathea kalbreyeri inhabits montane cloud forests and humid tropical forests at elevations between 1,500-3,000 meters in the Andes. The species requires consistently moist conditions and grows in the understory of primary and secondary forests, often along stream banks and in ravines where humidity levels remain high.
