The River Mur forms the border between Austria and Slovenia. The river flow is completely regulated. Riverine forest still exists but parts are no longer flooded. The agricultural land compromises a mosaic of arable fields, patches of forest and woodland, and small fish-ponds. Mixed forests dominate the valley sides, although in many places they have been replaced by Picea plantations.
The site is important for a number of breeding riverine forest and river species.
