Pavonia cauliflora

Declining

Overview

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

Pavonia cauliflora faces severe threats from ongoing deforestation and agricultural expansion within its extremely limited range in Brazil's Atlantic Forest. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation, while urban development pressures continue to reduce available forest patches. Climate change poses additional risks through altered precipitation patterns that could affect the specific microhabitat conditions this endemic shrub requires.

Threat summary

Habitat

This endemic Brazilian shrub inhabits remnant patches of Atlantic Forest (Mata Atlântica) in southeastern Brazil, typically growing in understory environments with high humidity and filtered sunlight. The species requires specific soil conditions and microclimate characteristics found only in well-preserved forest fragments.
