Turbinicarpus subterraneus
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Turbinicarpus subterraneus faces severe pressure from illegal collection for the international cactus trade, where its rarity makes it highly sought after by collectors. The species' extremely limited range in northeastern Mexico makes entire populations vulnerable to overcollection events. Habitat degradation from livestock grazing and agricultural expansion further threatens the specialized limestone substrate conditions this cactus requires for survival.
Habitat
This species inhabits specialized limestone outcrops and rocky slopes in the Chihuahuan Desert of northeastern Mexico. It grows in extremely arid conditions among sparse desert scrub vegetation, often in crevices and shallow soils derived from limestone substrates.
