Regulation No. 168 on the preservation of Geislafoss nature reserve, Audnedal municipality, Vest-Agder.

The purpose of this Regulation is to preserve a forest area dominated by deciduous forest on one side of Audna and a wooded area near the western boundary of continuous spruce forest on the east side of Audna, all-natural plant and animal life. The area has great ecological variation and contains habitats that are rich in elm-lime, alder-buckthorn forests with alder-design and old coniferous forests. The area is of special scientific interest, due to its diverse layout with native spruce east and west of the river, in an area where trees are of natural migration.
