Columnea poortmannii

Unknown

Overview

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

Columnea poortmannii faces severe population decline primarily due to deforestation and habitat fragmentation in its restricted Colombian range. Agricultural expansion and urban development have eliminated much of its native cloud forest habitat, while climate change threatens the specific moisture and temperature conditions this epiphytic species requires. The species' extremely limited distribution makes it particularly vulnerable to localized habitat destruction.

Threat summary

Habitat

This epiphytic plant inhabits the humid cloud forests of the Colombian Andes, typically growing on tree branches and trunks in areas with consistent moisture and filtered sunlight. It requires the specific microclimate conditions found in montane forests between 1,500-2,500 meters elevation.
