Rudgea vellerea

Declining

Overview

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

Rudgea vellerea faces significant pressure from ongoing deforestation and habitat fragmentation within Brazil's Atlantic Forest region. Agricultural expansion, particularly cattle ranching and crop cultivation, continues to reduce the species' already limited range. Urban development and infrastructure projects further fragment remaining forest patches, isolating populations and reducing genetic diversity.
