Actinostemon roseliae

Declining

Overview

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

Actinostemon roseliae faces severe pressure from agricultural expansion and cattle ranching activities that fragment and destroy its native forest habitat. Urban development and infrastructure projects further reduce available habitat, while the species' limited distribution makes it particularly vulnerable to localized threats. Climate change poses additional risks through altered precipitation patterns that could affect the specific microhabitat conditions this endemic species requires.

Threat summary

Habitat

This endemic Brazilian species inhabits Atlantic Forest remnants and associated forest ecosystems, typically found in humid montane forests with specific soil and moisture requirements. It occurs in areas with well-drained soils and partial canopy cover that provide the precise microclimate conditions necessary for its survival.
