Passiflora trisulca

Unknown

Overview

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

Passiflora trisulca faces severe pressure from agricultural expansion and urban development across its limited range in the Atlantic Forest region. Habitat fragmentation has isolated remaining populations, reducing genetic diversity and limiting natural regeneration. The species' specialized pollination requirements make it particularly vulnerable to ecosystem disruption, while invasive plant species compete for resources in degraded forest edges.

Threat summary

Habitat

This passion vine inhabits remnant Atlantic Forest fragments, typically growing in forest edges and clearings with partial shade. It requires well-drained soils and relies on intact forest ecosystems to support its specialized pollinator relationships.

Frequently asked questions

Why is Passiflora trisulca classified as Endangered?
Passiflora trisulca is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Passiflora trisulca faces severe pressure from agricultural expansion and urban development across its limited range in the Atlantic Forest region. Habitat fragmentation has isolated remaining populations, reducing genetic diversity and limiting natural regeneration. The species' specialized pollination requirements make it particularly vulnerable to ecosystem disruption, while invasive plant species compete for resources in degraded forest edges.
Where does Passiflora trisulca live?
Passiflora trisulca occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Passiflora trisulca?
The main threats to Passiflora trisulca are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
