Cynanchum nielsenii

Unknown

Overview

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

Cynanchum nielsenii faces significant pressure from habitat degradation in its limited range within the Canary Islands. The species is particularly vulnerable to urban development and agricultural expansion that fragments its specialized coastal and semi-arid habitats. Invasive plant species compete directly with this endemic milkweed, while climate change threatens to alter the delicate moisture balance required for its survival.
