Regulation No. 1655 on protection of Søndre Versvik natural reserve, Porsgrunn municipality, Telemark.

The purpose of this Regulation is to preserve a distinctive geological feature that is important for understanding of the Oslo field's fossil-bearing rocks and rare and vulnerable nature in the form of rich and threatened ash-dominated swamp forest types. The area extending to approx. 35 acres has a special scientific importance in terms of sediments with high educational and research value and particular importance for biodiversity due to elm-linden forests, reel-ash forest and alder-ash forests with species-rich and moss flora. The objective is to maintain conservation values in the most untouched state, and possibly developing them.
The natural reserve protection shall include the following safety regulations: vegetation, including dead trees and bushes, are protected against damage and destruction – it is therefore forbidden to remove plants and fungi or parts thereof from the reserve.

Littering is prohibited. d) Use of the natural reserve to major events is prohibited. e) hammering, drilling and blasting is prohibited. Collection of samples from bedrock or loose stones is prohibited. It is forbidden to inscribe in or paint on rock or boulders. f) Bonfires are forbidden.
