Cyathea estelae

Unknown

Overview

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

Cyathea estelae faces severe threats from deforestation and habitat conversion in its limited range within Costa Rican cloud forests. The species' extremely restricted distribution makes it particularly vulnerable to localized disturbances, while climate change poses additional risks by altering the specific temperature and humidity conditions required for this tree fern's survival. Agricultural expansion and infrastructure development continue to fragment the remaining suitable habitat.

Threat summary

Habitat

This tree fern is endemic to the montane cloud forests of Costa Rica, typically occurring at elevations between 1,200-2,000 meters. It requires the consistently moist, humid conditions characteristic of these cloud forest ecosystems, with their frequent fog cover and stable temperatures.

Why is Cyathea estelae classified as Critically Endangered?
Cyathea estelae 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 estelae faces severe threats from deforestation and habitat conversion in its limited range within Costa Rican cloud forests. The species' extremely restricted distribution makes it particularly vulnerable to localized disturbances, while climate change poses additional risks by altering the specific temperature and humidity conditions required for this tree fern's survival. Agricultural expansion and infrastructure development continue to fragment the remaining suitable habitat.
Where does Cyathea estelae live?
Cyathea estelae occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
