Senecio pseudoarnica Less. (Asteraceae) – a new non-native invading coastal areas in arctic and subarctic Europe.

Study Extent

Northern Europe

Sampling

We searched all available data sources to find information on the time of first importation of the species to Iceland and Norway including gardening books and catalogues, data from botanical gardens and other relevant sources. Data on the distribution of the species in Iceland and Norway were collected during field excursions carried out by the authors, by searching local databases in both countries as well as by directly contacting individuals reporting sightings of the species. Each occurrence point was confirmed by either collection stored in AMNH and TROM herbaria or at least by a hi-quality photograph. All occurrence points were georeferenced either directly by a GPS unit or indirectly
