Euphorbia hamaderohensis

Unknown

Overview

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

Euphorbia hamaderohensis faces severe pressure from overgrazing by livestock, particularly goats and camels, which browse on the succulent stems and prevent natural regeneration. The species' extremely limited range on Socotra Island makes it vulnerable to habitat degradation from expanding agricultural activities and infrastructure development. Climate change poses an additional threat through altered precipitation patterns that could affect the delicate moisture balance required for this desert-adapted euphorbia.

Threat summary

Habitat

This endemic euphorbia inhabits rocky limestone plateaus and steep escarpments in the arid interior of Socotra Island, typically growing in crevices and on cliff faces where it receives minimal rainfall. The species thrives in well-drained, alkaline soils at elevations between 200-800 meters, often associated with other Socotran endemic succulents.
