Gaylussacia oleifolia

Declining

Overview

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

Gaylussacia oleifolia faces severe pressure from agricultural expansion and urban development throughout its limited range in Brazil's Atlantic Forest region. The species' specialized habitat requirements make it particularly vulnerable to forest fragmentation, as remaining populations become increasingly isolated in small forest patches. Mining activities and infrastructure development have further reduced available habitat, while the species' slow growth rate and specific soil requirements limit its ability to colonize new areas or recover from disturbance.

Threat summary

Habitat

It shows a preference for partially shaded areas within secondary forest growth and forest margins, often associated with other endemic Atlantic Forest flora.
