Euphorbia randrianijohanyi

Unknown

Overview

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

Euphorbia randrianijohanyi faces severe pressure from agricultural expansion and slash-and-burn farming practices that destroy its specialized dry forest habitat in Madagascar. Mining activities and charcoal production further fragment the remaining forest patches where this endemic succulent occurs. The species' extremely limited range makes it particularly vulnerable to habitat conversion, as entire subpopulations can be eliminated by single development projects.
