The Biscutella rotgesii is listed as ‘Critically Endangered’ on the IUCN Red List of Threatened Species. This species grows on rocky grassland and serpentine rock in Corsica, managing the high concentrations of heavy metals in the soil and surviving on a limited supply of water.
Only several hundred individuals exist and sadly, these numbers are diminishing rapidly. As the Biscutella rotgesii is not internationally protected by any conventions, it is vulnerable to urbanization in its various forms, particularly the construction of roads and dams. In addition to these direct human pressures, flooding and fires also threaten this species’ existence.
The botanical garden of Porquerolles in France is storing and cultivating seeds. This important work should ideally be implemented by other botanical gardens. In addition, a management plan for the Natura 2000 site "Défilé de l'Inzecca" is being drafted and implemented as a way of raising awareness and saving this species.
