Pandanus calcis
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Pandanus calcis faces severe threats from limestone quarrying activities that directly destroy its specialized habitat on limestone outcrops. The species' extremely restricted range makes it particularly vulnerable to habitat modification, while its slow growth rate and specific soil requirements limit natural recovery. Urban development pressure in the region further fragments the remaining suitable habitat patches.
Habitat
This endemic pandanus species occurs exclusively on limestone karst formations and rocky outcrops in tropical regions. It requires well-drained, alkaline soils derived from limestone substrates and is typically found in open to semi-shaded conditions on cliff faces and limestone terraces.
