Serjania occidentalis

Unknown

Overview

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

Serjania occidentalis faces severe population decline primarily due to extensive habitat destruction from agricultural expansion and urban development across its limited range. The species' restricted distribution makes it particularly vulnerable to localized threats, with remaining populations fragmented and isolated. Invasive plant species compete directly with this native vine for resources and growing space, further reducing available habitat quality.

Threat summary
