In Slovenia, the olm is considered to be a vulnerable and potentially endangered species due to the high degree of endemism or limited spatial distribution. This is particularly true for the black olm subspecies: according to the criteria set out by the Red List and our current knowledge of the situation, we could even classify it as a critically endangered species, meaning it belongs among the most endangered vertebrates in the world.


Due to its rarity, the black olm is classified as vulnerable on the Red List of the Republic of Slovenia.

The main part of the black and white olm habitat is considered as a special Natura 2000 protected zone.


In terms of Slovenian legislation, the most important laws are the

Nature Conservation Act and the

Decree on Protected Wild Animal Species
