Tibouchina rigidula

Declining

Overview

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

Tibouchina rigidula faces severe pressure from agricultural expansion and urban development across its limited range in Brazil's Atlantic Forest region. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation, while cattle ranching and sugarcane cultivation continue to reduce available forest patches. Climate change poses an additional threat through altered precipitation patterns that could affect the humid montane conditions this species requires.

Threat summary

Habitat

Tibouchina rigidula is endemic to humid montane forests and forest edges in Brazil's Atlantic Forest biome, typically occurring at elevations between 800-1,500 meters. The species favors areas with consistent moisture and partial shade, often found along forest margins and in secondary growth areas recovering from past disturbance.
