Helicteres calcicola

Unknown

Overview

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

Helicteres calcicola faces severe threats from limestone quarrying and mining activities that directly destroy its specialized calcareous habitat. The species' extremely restricted range on limestone outcrops makes it particularly vulnerable to habitat fragmentation and complete local extinctions. Agricultural expansion and infrastructure development in the surrounding areas further reduce available habitat and create edge effects that degrade remaining populations.

Threat summary

Habitat

This species is endemic to limestone outcrops and calcareous soils in tropical regions, requiring the specific chemical and physical properties of calcium-rich substrates. It typically grows in rocky crevices and thin soils over limestone formations where few other plant species can establish.

Frequently asked questions

Why is Helicteres calcicola classified as Critically Endangered?
Helicteres calcicola 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. Helicteres calcicola faces severe threats from limestone quarrying and mining activities that directly destroy its specialized calcareous habitat. The species' extremely restricted range on limestone outcrops makes it particularly vulnerable to habitat fragmentation and complete local extinctions. Agricultural expansion and infrastructure development in the surrounding areas further reduce available habitat and create edge effects that degrade remaining populations.
Where does Helicteres calcicola live?
Helicteres calcicola occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Helicteres calcicola?
The main threats to Helicteres calcicola 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.
