The invasive raccoon dog (Nyctereutes procyonoides, gray) – an update of its distribution on the Balkans

The raccoon dog, which lives especially near water and is rare in areas with low humidity, has been spreading throughout Europe since its introduction to Western Russia in the beginning of the 20th century. Official accounts of its distribution in Europe are often inaccurate due to scarce data. A literature search was conducted to identify records of the raccoon dog in the Balkans. More than 60 records were identified, including ones unlisted by the cited source from central and western Bulgaria, southern Serbia, Macedonia, Bosnia, Herzegovina, and Greece. The raccoon dog can be found on the Balkans either along the Danube (which is a major corridor for its invasion) or along its tributaries, which might represent secondary invasion pathways
