Cynanchum serpyllifolium
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Cynanchum serpyllifolium faces severe population decline primarily due to habitat destruction from urban development and agricultural expansion across its limited range. The species' extremely restricted distribution makes it particularly vulnerable to localized threats, with remaining populations fragmented and isolated. Invasive plant species compete directly with this rare milkweed for resources, while climate change alters the specific microhabitat conditions it requires for survival.
Habitat
This critically endangered milkweed inhabits specialized rocky outcrops, limestone cliffs, and serpentine soils in Mediterranean-climate regions. It requires well-drained, mineral-rich substrates with specific pH conditions and typically grows in open areas with minimal canopy cover.
