Utvärdering av lockmedel för marklevande predatorer under midvintermånader i Norrbottens inland
Many invasive species propose a big threat against the native fauna in the area that they colonise. Today the raccoon dog (Nyctereutes procyonoides) is speeding from Finland over the border in to northern Sweden.
