Calycophyllum papillosum

Declining

Overview

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

Calycophyllum papillosum faces severe pressure from deforestation and agricultural expansion throughout its limited range in the Amazon basin. The species' valuable timber properties have led to selective logging pressure, while cattle ranching and crop cultivation continue to fragment its remaining forest habitat. Climate change poses an additional threat through altered precipitation patterns that may affect the seasonal flooding cycles critical to this species' reproductive success.

Threat summary

Habitat

This tree species inhabits lowland rainforests and seasonally flooded forests of the Amazon basin, typically growing in areas with rich alluvial soils. It occurs in both primary and secondary forest formations, often along riverbanks and in areas subject to periodic inundation.
