Toxicodendron calcicola
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.
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.
