Overview

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

Mammillaria manana faces severe threats from habitat destruction due to urban expansion and agricultural conversion in its extremely limited range. The species is further endangered by illegal collection for the horticultural trade, as its distinctive appearance makes it highly sought after by cactus collectors. Climate change poses an additional threat through altered precipitation patterns that could disrupt the delicate moisture balance this desert species requires.
