Rudgea insignis

Declining

Overview

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

Rudgea insignis faces severe pressure from ongoing deforestation and habitat fragmentation across its limited range in the Atlantic Forest of southeastern Brazil. Agricultural expansion, particularly cattle ranching and sugarcane cultivation, continues to reduce and isolate remaining forest patches. Urban development and infrastructure projects further fragment the species' already restricted habitat, while selective logging degrades forest quality even in protected areas.

Threat summary
