Changing aims over time 1920 -What are the forest resources Improving forest state Subsidies 1940 - status of regeneration Cutting level 1980 environmental and ecological considerations 1990 Biodiversity, changed forestry act and forestry practises, carbon Ulf Söderberg, Long-term continuity for NFI © SLU 1/11/2022 • Slide no. 2

Use of NFI data • • Forest policy decisions Forestry programmes Planning of forest industry investments Nature conservation policy Carbon accounting and reporting Large scale forest management planning Data for research Ulf Söderberg, Long-term continuity for NFI © SLU 1/11/2022 • Slide no. 3

Use of NFI data (cont. ) • Data for long-term scenarios of forest resources development on national level • County forestry planning • Information forest land taxation Ulf Söderberg, Long-term continuity for NFI © SLU 1/11/2022 • Slide no. 4

Main scenarios Reference Environment Present silviculture, decided environmental policy until year 2010 and effects of changed climate. Increased environmental ambitions that are considered to fulfil the environmental quality objectives. Production Increased wood production based on a high but reasonable level of investments in forestry. Ulf Söderberg, Long-term continuity for NFI Environment + Production Both increased environmental ambitions and increased wood production. © SLU 1/11/2022 • Slide no. 8

The Heureka regional simulator • Will enable integrated analyses of the development of the forest ecosystem at the regional level (100 years). • Initial forest state described by NFI data and other data • Simulation of management alternatives specified by user. • Will handle many utilities such as timber, forest fuel, biodiversity, recreation, carbon sequestration and soil. • Results (tables, charts and maps) output to users for decision support. Ecosystem processes and Management activities Period t Description of initial state (NFI data and other data) Period t + 2 Period t + 1 Future forest state and production of goods and services (timber, forest fuel, biodiversity, recreation, carbon, etc) Ulf Söderberg, Long-term continuity for NFI © SLU 1/11/2022 • Slide no. 11
