Toxicodendron calcicola

Unknown

Overview

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

Toxicodendron calcicola faces severe pressure from limestone quarrying and mining activities that directly destroy its specialized calcareous habitat. Urban development and agricultural expansion in its limited range further fragment remaining populations. The species' narrow ecological requirements and restricted distribution make it particularly vulnerable to habitat modification and climate-induced changes to soil chemistry.

Threat summary

Habitat

This species is endemic to limestone outcrops and calcareous soils in specialized karst environments. It typically grows on rocky slopes and cliff faces where calcium-rich substrates create unique microhabitat conditions.

Frequently asked questions

Why is Toxicodendron calcicola classified as Endangered?
Toxicodendron calcicola is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Toxicodendron calcicola faces severe pressure from limestone quarrying and mining activities that directly destroy its specialized calcareous habitat. Urban development and agricultural expansion in its limited range further fragment remaining populations. The species' narrow ecological requirements and restricted distribution make it particularly vulnerable to habitat modification and climate-induced changes to soil chemistry.
Where does Toxicodendron calcicola live?
Toxicodendron 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 Toxicodendron calcicola?
The main threats to Toxicodendron 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.
