Passiflora jamesonii

Unknown

Overview

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

Passiflora jamesonii faces significant pressure from agricultural expansion and cattle ranching in Ecuador's Andean cloud forests, where its specialized pollination requirements make it particularly vulnerable to habitat fragmentation. The species' limited altitudinal range between 1,800-3,000 meters makes it susceptible to climate-driven shifts in cloud forest zones. Collection pressure for horticultural trade has also contributed to population declines in accessible areas.

Threat summary

Habitat

This passion vine inhabits Ecuador's montane cloud forests and forest edges at elevations between 1,800-3,000 meters, where persistent mist and high humidity create ideal conditions for epiphytic growth. It typically grows as a climbing vine in secondary forest margins and disturbed areas within the cloud forest ecosystem.
