Iryanthera dialyandra

Declining

Overview

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

Iryanthera dialyandra faces significant pressure from deforestation and habitat fragmentation across its Amazonian range. Agricultural expansion, particularly cattle ranching and soy cultivation, continues to reduce available lowland rainforest habitat. Logging operations targeting valuable timber species also degrade the forest structure this nutmeg species depends upon for reproduction and dispersal.

Threat summary

Habitat

This Amazonian nutmeg species inhabits lowland tropical rainforests, typically found in terra firme forests on well-drained soils. It occurs in both primary and secondary forest formations across the western Amazon basin, particularly in areas with high canopy cover and diverse understory vegetation.
