[1] Geologically, the Zelengora range is part of the Dinaric Alps and formed largely of secondary and tertiary sedimentary rock, mostly limestone.

The mountains of Zelengora were not part of the frontline during the 1990-1995 conflict and therefore have virtually no contamination with land mines and unexploded ordnance.

[3] Earlier though, in 1943, Zelengora became the scene of fierce combat during the Second World War, especially in a decisive phase of the Battle of the Sutjeska.

The wildness of the nature and the complete lack of signs of modern civilization gives these mountains a special appeal.

The protection as part of the Sutjeska National Park of a large area of these mountains safeguards the integrity of the wilderness.
