Eugenia janeirensis

Declining

Overview

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

Eugenia janeirensis faces severe pressure from urban expansion and infrastructure development throughout the Rio de Janeiro metropolitan region, where its Atlantic Forest habitat has been reduced to small, fragmented patches. The species is particularly vulnerable to habitat degradation from residential construction, road building, and industrial activities that continue to encroach on remaining forest fragments. Additional threats include invasive plant species that compete for resources and alter the understory composition where this endemic tree naturally occurs.
