Cnidoscolus magni-gerdtii

Declining

Overview

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

Cnidoscolus magni-gerdtii faces severe threats from agricultural expansion and urban development within its extremely restricted range in northeastern Brazil. The species' limited distribution makes it particularly vulnerable to habitat fragmentation, as even small-scale land conversion can eliminate significant portions of its remaining population. Overgrazing by livestock and collection pressure for traditional medicinal uses further compound the decline of this endemic spurge.

Threat summary

Habitat
