Acanthocladus santosii

Declining

Overview

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

Acanthocladus santosii faces severe pressure from habitat destruction as coastal development and agricultural expansion fragment its limited range. The species' restricted distribution makes it particularly vulnerable to localized threats, while collection pressure for horticultural trade has further reduced wild populations. Climate change poses an additional long-term threat through altered precipitation patterns affecting this drought-adapted species.
