Cynanchum spruceanum
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Cynanchum spruceanum faces severe threats from ongoing deforestation and agricultural expansion throughout its limited range in the Amazon Basin. The species' specialized habitat requirements make it particularly vulnerable to forest fragmentation, as it depends on specific canopy conditions and host trees for support. Mining activities and infrastructure development have further reduced available habitat, while climate change may alter the humid conditions essential for this vine's survival.
Habitat
This climbing vine inhabits humid lowland rainforests of the Amazon Basin, typically growing in the understory and lower canopy where it relies on host trees for structural support. The species requires consistently moist conditions and appears to be restricted to primary forest environments with minimal human disturbance.
