Species Profile
Hornungia petraea is a small flowering plant in the family Brassicaceae. It is native to Europe and parts of North Africa and the Middle East.
Hutchinsia petraea (Rock Hutchinsia) faces severe population declines primarily due to habitat loss and degradation of its specialized rocky outcrop and limestone pavement habitats. Urban development, quarrying activities, and changes in land management practices have significantly reduced available suitable habitat. Climate change may also be affecting the species through altered precipitation patterns and temperature regimes in its restricted range.
