Rudgea obesiflora

Unknown

Overview

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

Rudgea obesiflora 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 crop cultivation, continues to reduce and isolate remaining forest patches where this endemic shrub occurs. Urban development and infrastructure projects further fragment the species' already restricted habitat, while climate change may alter the specific microclimatic conditions this species requires in montane forest environments.
