Geostachys rupestris

Declining

Overview

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

Geostachys rupestris faces severe threats from habitat destruction due to limestone quarrying and mining activities in its restricted range. The species' extremely limited distribution makes it highly vulnerable to localized disturbances, while invasive plant species compete for the specialized rocky crevice habitats it requires. Climate change poses additional risks through altered precipitation patterns affecting the delicate moisture balance of its limestone cliff ecosystems.

Threat summary

Habitat

This critically endangered plant species is endemic to limestone cliffs and rocky crevices in highly specialized karst environments. It requires specific moisture conditions and soil chemistry found only in narrow bands of exposed limestone formations.

Frequently asked questions

Why is Geostachys rupestris classified as Critically Endangered?
Geostachys rupestris is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Geostachys rupestris faces severe threats from habitat destruction due to limestone quarrying and mining activities in its restricted range. The species' extremely limited distribution makes it highly vulnerable to localized disturbances, while invasive plant species compete for the specialized rocky crevice habitats it requires. Climate change poses additional risks through altered precipitation patterns affecting the delicate moisture balance of its limestone cliff ecosystems.
Where does Geostachys rupestris live?
Geostachys rupestris occurs in Malaysia. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Geostachys rupestris?
The main threats to Geostachys rupestris are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
