Calathea congesta

Unknown

Overview

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

Calathea congesta faces severe pressure from deforestation and agricultural expansion throughout its native range in tropical South America. The species' specialized habitat requirements make it particularly vulnerable to forest fragmentation, as it depends on the stable microclimatic conditions found in intact understory environments. Mining activities and infrastructure development have further reduced available habitat, while climate change threatens to alter the humid conditions essential for this moisture-dependent species.

Threat summary

Habitat

Calathea congesta inhabits the humid understory of lowland tropical rainforests, typically growing in areas with consistent moisture and filtered sunlight. The species thrives in well-drained but moisture-retentive soils along forest edges and in secondary growth areas within its native range.
