Acharagma aguirreana

Unknown

Overview

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

Acharagma aguirreana faces severe threats from limestone quarrying operations that directly destroy its specialized habitat in the Sierra de la Paila mountains. Urban expansion and agricultural development in the surrounding valleys continue to fragment the remaining populations. Climate change poses an additional risk through altered precipitation patterns that could affect the delicate moisture balance this desert cactus requires for survival.
