Room for all species to thrive
Holmen works hard to ensure that all the species that live in the forest can continue to thrive. We have therefore been working actively for many years on nature conservation that makes a positive contribution to biodiversity. Biodiversity is made up of a complex interaction between many species in different natural habitats and different types of forest environments must be nurtured in order to preserve it.
Forests with special assets
Some forests have large or unique assets that should be preserved. At Holmen we have procedures in place to identify such forests, within Holmen’s own holdings, when purchasing wood from other forest owners and through group certification of private forest owners. Forests have high conservation value for various reasons. For Holmen these include:
- Areas with high concentrations of endangered species and/or key biotopes and that the Swedish Environmental Protection Agency has classified as being of national interest for nature conservation
- Forest along the tree line
- Forest in water protection areas
We take the assets of these forests into account in our forest management and this is incorporated in our ecological landscape plans. When harvesting in water protection areas, we follow the requirements set for activities in the area.
Planning is the basis of active and sustainable forestry that takes into account natural, cultural and social assets.
Every ten years we conduct a survey of all of our forest holdings and calculate the potential harvest in a hundred years’ time. The calculations also take into account montane forests, conservation efforts, reindeer husbandry and social values. Both volumes of standing forest and the forest’s growth continue to increase.
Holmen’s forests and their values are also described extensively in local ecological landscape plans. These are living documents kept constantly up to date. The plans contain strategies on how to plan areas set aside for nature conservation, and how the forests are to be managed in the long term in order to preserve natural assets and create new ones.
Wetlands and watercourses
Wetlands are important for the balance of nature. They clean the water and benefit biodiversity, not least birdlife. Wetlands also offer an attractive environment for recreation and birdwatching.
In partnership with the Swedish Wetlands Fund, Holmen has so far created or restored around 40 wetlands. These form habitats for a wealth of animal and plant species. Many birds nest here and the wetlands also serve as stopover sites on long migrations.
The extensive system for floating timber in Sweden resulted in many smaller watercourses being cleared or straightened. Later forest road construction also affected many watercourses, creating obstacles for fish and aquatic organisms because of poor culvert designs. Extensive work has been carried out to address such obstacles to migration in different parts of Sweden.
