Dialium holtzii

Unknown

Overview

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

Dialium holtzii faces severe pressure from agricultural expansion and logging activities throughout its East African range. The species' slow growth rate and specific soil requirements make it particularly vulnerable to habitat fragmentation, as remaining populations become isolated in forest patches too small to maintain genetic diversity. Charcoal production and fuelwood collection further threaten mature trees, while climate change is altering precipitation patterns critical for seedling establishment.

Threat summary

Habitat

Dialium holtzii occurs in lowland and montane forests of East Africa, typically growing in well-drained soils at elevations between 200-1,500 meters. The species favors forest edges and secondary growth areas, often establishing in gaps created by natural disturbances within both dry and moist forest ecosystems.
