Geissanthus lehmannii

Declining

Overview

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

Geissanthus lehmannii faces severe threats from ongoing deforestation and habitat conversion in Colombia's Andean cloud forests. The species' extremely restricted range makes it particularly vulnerable to localized disturbances, while agricultural expansion and infrastructure development continue to fragment its remaining habitat. Climate change poses an additional threat by altering the specific moisture and temperature conditions required by this cloud forest endemic.

Threat summary

Habitat

Geissanthus lehmannii is endemic to the cloud forests of the Colombian Andes, typically occurring at elevations between 1,800-2,400 meters. These montane forests are characterized by persistent cloud cover, high humidity, and epiphyte-rich vegetation that provides the specific microclimate conditions required by this specialized plant species.

Why is Geissanthus lehmannii classified as Critically Endangered?
Geissanthus lehmannii 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. Geissanthus lehmannii faces severe threats from ongoing deforestation and habitat conversion in Colombia's Andean cloud forests. The species' extremely restricted range makes it particularly vulnerable to localized disturbances, while agricultural expansion and infrastructure development continue to fragment its remaining habitat. Climate change poses an additional threat by altering the specific moisture and temperature conditions required by this cloud forest endemic.
Where does Geissanthus lehmannii live?
Geissanthus lehmannii occurs in Colombia. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
