Calathea ischnosiphonoides

Unknown

Overview

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

Calathea ischnosiphonoides 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 species.

Threat summary

Habitat

This species inhabits the humid understory of Atlantic Forest rainforests in southeastern Brazil, requiring consistent moisture and filtered light conditions. It typically grows in rich, well-drained soils beneath the forest canopy where humidity levels remain high year-round.
