Duvaliandra dioscoridis
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Duvaliandra dioscoridis faces severe threats from habitat destruction due to agricultural expansion and urban development across its limited range in the Arabian Peninsula. Overgrazing by livestock has degraded the arid shrubland ecosystems where this succulent species occurs, while climate change intensifies drought conditions in an already water-stressed environment. The species' extremely restricted distribution makes it particularly vulnerable to localized disturbances and collection pressure from succulent enthusiasts.
Habitat
This species inhabits rocky outcrops and gravelly slopes in arid shrubland and semi-desert environments of the Arabian Peninsula. It typically grows in well-drained soils among sparse vegetation at elevations between 200-800 meters.
