Overview

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

Galium rotundifolium faces severe pressure from habitat destruction as its specialized limestone cliff and rocky outcrop environments are increasingly disturbed by quarrying activities and infrastructure development. The species' extremely limited distribution across fragmented populations makes it particularly vulnerable to local extinctions, while climate change threatens to alter the specific microclimatic conditions required for its survival on exposed rock faces.

Threat summary

Habitat

This specialized plant inhabits limestone cliffs, rocky outcrops, and crevices in calcareous substrates, typically found on exposed or semi-shaded rock faces in mountainous regions. It requires specific soil chemistry and drainage conditions provided by limestone geology, often growing in thin soil accumulations within rock fissures.
