Dorstenia nummularia

Unknown

Overview

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

Dorstenia nummularia faces severe threats from habitat destruction due to urban expansion and agricultural conversion in its limited range. The species' extremely restricted distribution makes it particularly vulnerable to localized disturbances, while collection pressure for horticultural trade has further reduced wild populations. Climate change poses an additional threat through altered precipitation patterns affecting the specialized microhabitats this succulent requires.
