The changes begin with a more detailed timeline and role description for each involved authority, particularly in relation to natural hazards like avalanches and landslides. The updated Chapter 2 introduces a stepwise description of how regional regulations are now to be drafted and coordinated between counties and municipalities, including legal requirements for public hearings and national publication of regulations.

In Chapter 3, the guide now includes extended criteria and new typologies for protective forest classification. It distinguishes between forests that prevent snow avalanches, rockfalls, or floods and redefines each skredtype’s area of effect, such as løsneområde and utløpssone. New visual diagrams clarify the impact zones and the effectiveness of forest cover in each hazard type.

Chapter 4 revises how logging activity is governed within protective forest boundaries. The concept of småflatehogst (small patch logging) has been moved from “closed” to “open” felling forms, and new enforcement principles have been added regarding stopping unauthorized logging activity. Additionally, restrictions are now differentiated more explicitly by the type of hazard the forest protects against.

The 2025 revision also fully rewrites Chapter 5, detailing new requirements for timber harvesting notices (hogstmelding) and how authorities must process them. Similarly, Chapter 6 overhauls the structure and required content for future regional forest regulations.

Appendices in Chapter 7 are updated to include a new product specification for digital mapping data, along with simplified templates that allow regional authorities to tailor local forest regulations. It also includes revised illustrations showing principles for mapping various natural hazard types.

These changes aim to create consistency across Norway’s counties by enforcing updated definitions of protective forests, hazard types, and forest management roles in light of increasing climate-related risks​.
