Aspidosperma nigricans

Declining

Overview

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

Aspidosperma nigricans faces severe pressure from deforestation and habitat fragmentation across its limited range in the Amazon Basin. The species is particularly vulnerable to selective logging operations that target valuable timber species, as well as agricultural expansion that converts primary forest to cattle pasture and cropland. Its slow growth rate and specific soil requirements make population recovery extremely difficult once local populations are eliminated.

Threat summary

Habitat

This tree species inhabits lowland tropical rainforests of the Amazon Basin, typically growing in well-drained soils on terra firme (non-flooded) forest areas. It occurs in primary forest environments with high canopy cover and is associated with specific soil chemistry conditions that limit its distribution.
