Dichrostachys dehiscens

Unknown

Overview

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

Dichrostachys dehiscens faces significant pressure from agricultural expansion and livestock grazing across its limited range in Madagascar's dry forests. Slash-and-burn agriculture for rice cultivation and cattle ranching has fragmented its habitat, while overgrazing by zebu cattle prevents natural regeneration of seedlings. The species' slow growth rate and specific soil requirements make recovery particularly challenging once populations are disturbed.
