Landscaping

• All Holmen Skog’s districts draw up an

ecological landscape plan for their geographic

area.

• The ecological landscape plan comprises:

– Description of the area’s forest history, climate,

aquatic environments, the forest’s age and the

species of wood in the area.

– Inventory of existing natural, cultural and social

assets.

– Assessment of what habitats are wholly or

partially lacking in the current forest landscape.

• Based on the results, long-term targets are

drawn up for preserving or improving the natural

assets by re-establishing missing habitats.
