Red List Category not transferable; e. g. for a taxon that has been listed in the previous Red List but not in identical taxonomic coverage.
Change of category compared to previous Red List
The change of category is not assessable, for example because the previous Red List does not list the taxon or the taxon has not been assessed in the previous Red List.
Further comments
Die wahrscheinlich überwiegend aus einem Tierpark stammenden Kanadischen Biber im nördlichen Rheinland-Pfalz werden auf Initiative der Gesellschaft für Naturschutz und Ornithologie Rheinland-Pfalz (GNOR) eingefangen, genetisch überprüft (Chromosomenzahl), kastriert und wieder freigelassen. Hierdurch wird langfristig eine Vermehrung der Art unterbunden (IPOLA 2018).
Status
