Dorstenia rocana

Unknown

Overview

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

Dorstenia rocana faces severe threats from habitat destruction due to urban expansion and agricultural development on Roca Island. The species' extremely limited range makes it particularly vulnerable to any environmental disturbance, while invasive plant species compete for the limited suitable habitat. Climate change poses additional risks through altered precipitation patterns that could affect the specialized microhabitats this endemic species requires.

Threat summary

Habitat

Dorstenia rocana is endemic to Roca Island in the Gulf of Guinea, where it inhabits rocky outcrops and cliff faces in coastal and montane environments. The species grows in crevices and on ledges with well-drained soils, typically in areas with partial shade and high humidity.
