CALLIANTHEMUM KERNERANUM (Calliantemo di Kerner. Kerners Schumuckblume. Callianthème de Kerner). Ranunculaceae Callianthemum kernerianum occurs only at the narrow mountain ridge of Mt. Baldo in Italy with an extent of occurrence and an area of occupancy of 20 km. The population trend seems to be stable, but a population reduction in the near future is possible, due to increased tourist impact (trekking and skiing ). Callianthemum kernerianum occurs in a protected area and monitoring is underway but in addition to those measures, fences should be erected and the trekking paths should be changed in order to preserve this plant. Because of its rarity, the very small area it inhabits and the existing threats, it is classed as Critically Endangered.
