Columnea rubribracteata

Unknown

Overview

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

Columnea rubribracteata faces severe pressure from deforestation and agricultural expansion throughout its limited range in Costa Rican cloud forests. The species' specialized epiphytic lifestyle makes it particularly vulnerable to habitat fragmentation, as it requires mature forest canopy structure for survival. Climate change poses an additional threat by altering the moisture regimes essential for this cloud forest specialist, potentially shifting suitable habitat to higher elevations where less area is available.

Threat summary

Habitat

This epiphytic plant inhabits the canopy of tropical montane cloud forests in Costa Rica, typically growing on moss-covered branches and trunks in areas with persistent fog and high humidity. It occurs at elevations between 1,200-2,000 meters where cool temperatures and constant moisture create ideal conditions for epiphytic growth.
