Calathea anulque

Unknown

Overview

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

Calathea anulque faces severe pressure from deforestation and agricultural expansion throughout its limited range in the Atlantic Forest of Brazil. The species' specialized habitat requirements make it particularly vulnerable to forest fragmentation, as it depends on the humid understory conditions of intact rainforest. Mining activities and urban development have further reduced available habitat, while climate change threatens to alter the moisture regimes essential for this moisture-dependent plant.

Threat summary

Habitat

Calathea anulque inhabits the humid understory of Atlantic Forest rainforests in southeastern Brazil, typically growing in shaded areas with consistently moist soils. The species requires the stable microclimate conditions found beneath the forest canopy, including high humidity and protection from direct sunlight.
