Rudgea stenophylla

Unknown

Overview

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

Rudgea stenophylla 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 understory species requires.

Rudgea stenophylla is endemic to the Atlantic Forest (Mata Atlântica) of southeastern Brazil, where it grows as an understory shrub in humid montane forests. The species typically occurs in shaded forest environments with high humidity and stable temperatures, often on slopes and in valleys within the remaining forest fragments.
