Pavonia gerleniae

Declining

Overview

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

Pavonia gerleniae faces severe threats from agricultural expansion and urban development within its extremely 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 encroach on remaining forest patches. Climate change poses additional pressure through altered precipitation patterns that could affect the specific microhabitat conditions this endemic species requires.

Threat summary

Habitat

This endemic Brazilian species inhabits remnant Atlantic Forest fragments, typically found in understory environments with specific soil and moisture requirements. It occurs in areas with well-drained soils and partial shade conditions within the highly threatened Atlantic Forest biome.
