CRCritically Endangered

Billbergia ambigua

Unknown

Overview

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

Billbergia ambigua faces severe population decline due to extensive deforestation and habitat fragmentation within its restricted range in Brazil's Atlantic Forest. Urban expansion and agricultural conversion have eliminated much of its native bromeliad habitat, while remaining populations are increasingly isolated in small forest fragments. The species' specialized epiphytic lifestyle makes it particularly vulnerable to canopy loss and microclimate changes.
Threat summary

Habitat

This epiphytic bromeliad inhabits the canopy and understory of Brazil's Atlantic Forest, growing on tree trunks and branches in humid, shaded environments. It occurs in both primary and secondary forest remnants at elevations typically below 800 meters.
