Cadaba insularis

Declining

Overview

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

Cadaba insularis faces severe threats from its extremely restricted range on small islands, making it vulnerable to habitat destruction and environmental changes. The species is threatened by coastal development, invasive plant species that compete for limited resources, and potential sea-level rise affecting its low-lying island habitats. Human activities including tourism infrastructure and agricultural expansion further fragment its already limited habitat.

Threat summary

Habitat

Cadaba insularis is endemic to small islands where it inhabits coastal scrublands, rocky shores, and dry woodland areas. The species typically grows in well-drained soils near the coast, often in association with other drought-tolerant vegetation adapted to saline conditions.
