Mammillaria berkiana
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Mammillaria berkiana faces severe pressure from illegal collection for the international cactus trade, with its distinctive appearance making it highly sought after by collectors. Urban expansion and agricultural development in its limited range in Hidalgo, Mexico, continue to fragment and destroy its specialized limestone habitat. Mining activities and quarrying operations pose additional threats to the rocky outcrops where this species naturally occurs.
Habitat
This species is endemic to limestone hills and rocky outcrops in the state of Hidalgo, Mexico, where it grows in crevices and on steep slopes in semi-arid scrubland. It typically occurs at elevations between 1,200-1,800 meters in areas with well-drained, calcareous soils and sparse vegetation cover.
