Kerianthera longiflora

Declining

Overview

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

Kerianthera longiflora faces severe pressure from deforestation and agricultural expansion across its limited range in the Atlantic Forest of Brazil. The species' specialized pollination requirements and narrow habitat preferences make it particularly vulnerable to forest fragmentation, which disrupts ecological relationships essential for reproduction. Mining activities and urban development continue to reduce available habitat, while climate change threatens to shift suitable growing conditions beyond the species' adaptive capacity.

Threat summary

Habitat

Kerianthera longiflora is endemic to the Atlantic Forest (Mata Atlântica) of southeastern Brazil, where it grows in humid montane forests and forest edges at elevations between 800-1,500 meters. The species requires well-drained soils and partial shade conditions typical of the region's highly biodiverse but severely fragmented forest ecosystem.
