Dioscorea rosei

Unknown

Overview

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

Dioscorea rosei faces significant pressure from agricultural expansion and urban development throughout its limited range in Mexico. The species is particularly vulnerable due to its restricted distribution and specialized habitat requirements, with wild populations declining as traditional forest areas are converted to farmland and settlements. Overcollection for traditional medicinal uses has further reduced wild populations, as the tuberous roots are harvested for their therapeutic properties.
