Regulation No. 152 on the protection of the Gukilhøgda natural reserve, Trøgstad and Aurskog-Holand municipalities, Østfold and Akershus.

The purpose of this Regulation is to preserve an area of high proportion of highly productive forest with rough grown spruce. The sediment-rich sections of the site represent a forest vulnerable and very rare in Norway. The North-facing position and stabilizing soil moisture provides a particularly humid climate where its vegetation is of small fern type with elements of low herb. The goal is to maintain conservation values ​​in the most pristine conditions, and possibly developing them. National authorities may grant exemption with regard to measures in connection with the management of wildlife and fish; maintenance and management of cultural heritage; and the maintenance of old drainage ditches on land.
