Rudgea microcarpa

Unknown

Overview

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

Rudgea microcarpa faces significant pressure from ongoing deforestation and habitat fragmentation across its Atlantic Forest range in southeastern Brazil. Agricultural expansion, particularly cattle ranching and crop cultivation, continues to reduce and isolate remaining forest patches where this understory shrub depends on stable microclimatic conditions. Urban development and infrastructure projects further fragment the species' already restricted habitat, while climate change may alter the humid forest conditions essential for its survival.

Threat summary

Habitat

Rudgea microcarpa inhabits the understory of humid Atlantic Forest remnants in southeastern Brazil, typically growing in shaded areas with rich, well-drained soils. This shrub species requires the stable microclimatic conditions found in mature forest fragments, particularly areas with consistent moisture and protection from direct sunlight.
