Priorities in plant species conservation are often based on national Red Lists. In an international context, however, the Red List status (threat) of a species within a limited territory may be misleading because the local disappearance of a species may or may not have serious implications for its global persistence. A second important aspect to consider in species conservation is therefore the responsibility of a country for the species, i.e. the importance of the conservation of local populations for the persistence of the species worldwide. In this contribution, we assess the responsibility of Switzerland for its vascular flora using three biogeographical criteria: (1) the Swiss portion of the species range (high responsibility for species with a large fraction of the range in Switzerland), (2) the degree of endemism (high responsibility for species with a small total range) and (3) the degree of isolation (high responsibility for isolated outposts, which may contain a large part of a species’ genetic variation). The three criteria were derived for each species from global and European distribution maps, and were then combined to an overall index of responsibility. On this basis, 397 taxa for which Switzerland has an intermediate to high international responsibility were identified. These are almost 15% of the whole vascular flora of Switzerland. Of the 397 taxa, 75% are endemic species of the Alps, and 48% are threatened taxa within Switzerland. The Responsibility List can be used together with the Red List to set priorities in plant conservation or to identify areas of particular floristic value.
