Karwinskia orbiculata

Unknown

Overview

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

Karwinskia orbiculata faces severe population decline primarily due to habitat destruction from agricultural expansion and urban development in its restricted range. The species' extremely limited distribution makes it particularly vulnerable to localized threats, with remaining populations fragmented and isolated. Overgrazing by livestock has further degraded the dry forest and scrubland habitats essential for this shrub's survival.

Threat summary

Habitat

Karwinskia orbiculata inhabits dry tropical forests and thorny scrublands in arid and semi-arid regions of Mexico. The species typically grows in rocky soils and limestone substrates at elevations between 200-800 meters, often associated with other drought-adapted shrubs and cacti.
