Dialium rondoniense

Declining

Overview

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

Dialium rondoniense faces severe pressure from agricultural expansion and cattle ranching throughout its limited range in the Brazilian Amazon. Deforestation rates in Rondônia state, where this species is endemic, remain among the highest in Brazil, with soybean cultivation and pasture conversion eliminating critical forest habitat. The species' restricted distribution makes it particularly vulnerable to localized habitat destruction, while selective logging targets mature trees of the Dialium genus for their valuable timber.

Threat summary

Habitat

This endemic tree species inhabits lowland tropical rainforests of Rondônia state in the Brazilian Amazon. It occurs in primary forest areas with well-drained soils, typically as part of the forest canopy in areas with high biodiversity and complex forest structure.
