Pseudobombax calcicola

Declining

Overview

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

Pseudobombax calcicola faces severe pressure from limestone quarrying and mining activities that directly destroy its specialized habitat. Agricultural expansion and urban development in the Dominican Republic continue to fragment the remaining populations of this endemic tree. The species' extremely restricted range on limestone substrates makes it particularly vulnerable to habitat conversion, with several known populations already lost to quarrying operations.

Threat summary
