Rudgea erythrocarpa

Declining

Overview

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

Rudgea erythrocarpa faces severe pressure from ongoing deforestation and habitat fragmentation across its limited range in Atlantic Forest remnants. Agricultural expansion, particularly cattle ranching and crop cultivation, continues to reduce and isolate the remaining forest patches where this endemic shrub occurs. Urban development and infrastructure projects further fragment its already restricted habitat, while the species' apparent narrow ecological requirements make it particularly vulnerable to these landscape-level changes.

Threat summary

Habitat

This endemic Brazilian shrub inhabits understory areas of Atlantic Forest remnants, typically occurring in humid montane and submontane forests. It appears to favor shaded environments with well-developed canopy cover and rich organic soils characteristic of mature forest ecosystems.
