- 1. Introduction to nature restoration Part 2 Ecology Astrid B. Skrindo Astrid.Skrindo@nina.no Date: Autumn 2024
- 2. We need knowledge about: 2 Society's framework conditions Practical knowledge and experience Ecology This varies greatly from project to project, we won't go into it in depth here, but REMEMBER it's important! You know this better than I do, and we'll come back to it in practical courses! Knowledge of ecology makes nature restoration different from other construction work, so everyone needs a little refresher and/or new knowledge. It starts now:
- 3. Why do we need knowledge about ecology? 3
- 5. Climate + nature = true Nature needs more space and intact nature copes better with extreme weather... Examples from the extreme weather "Hans" in 2023:
- 6. Legislation -NATURMANGFOLDLOVEN § Section 1 Purpose of the Act The purpose of the Act is to ensure that nature with its biological, landscape and geological diversity and ecological processes is preserved through sustainable use and protection, also so that it provides a basis for human activity, culture, health and well-being, now and in the future, also as a basis for Sami culture. Figure from WWF Photo: A.B.Skrindo The most important threats to biodiversity: 1. Area change 2. Overharvesting 3. Climate change 4. Pollution 5. Harmful alien species 6. Others...

- 9. What are the differences between nature and nature and how is everything connected? 9
- 10. Classification of nature Nature in Norway - NiN Nature systems - main types: Sea Snow and ice systems Marine bottom systems Marine water mass systems Country Snow and ice systems Fastmark systems Wetland systems Fresh water Limnic water body systems Seabed systems Riverbed systems Main ecosystem map for Norway 10 https://nibio.brage.unit.no/nibio-xmlui/ https://naturinorge.artsdatabanken.no

- 12. Some relevant ecological processes and concepts • Succession • Resistance and robustness • Alternative stable stages • Eye theory and connectivity • Symbiosis and other dependent relationships • Biological diversity • Individual, population and society • Niche and habitat • Supply chain and business networks 12 Ecological theory helps us understand the effects of restoration measures
- 13. Succession
- 14. Resistance and recilience Resistance Resillience Completely destroyed Restoration? The ability to resist disruption The ability to recover quickly after disruption An ecosystem that has been completely destroyed. Can you restore what was or create something completely new?
- 15. Eye theory and connectivity
- 16. Eye theory and connectivity
- 17. Symbiosis and other cohabitation 17 Lichen is a symbiosis between a fungus and a blue-green algae. The different parts cannot survive on their own. Bees need nectar from the flower in order to live, the flower needs the bees to carry out propagation
- 18. Biological diversity And: individual, population and community 18 A forest is not a forest...
- 19. Ecosystems, food chains, niches, habitats.... 19
- 20. Now it's time to integrate ecological knowledge into practice and framework conditions! 20 Society's framework conditions Practical knowledge and experience Ecology This varies greatly from project to project, we won't go into it in depth here, but REMEMBER it's important! You know this better than I do, and we'll come back to it in practical courses! Knowledge of ecology makes nature restoration different from other construction work, so everyone needs a little refresher and/or new knowledge. It starts now:

Editor's Notes
- #4: Risk of restoration becoming "all or nothing" In order to "categorise", this division into three axes may be useful - to find your place in space. NB - there can be mutual exchange of knowledge, restoration methods, solutions, actors, collaborative relationships ++ between the three axes
- #7: Nature encroachment is still the biggest threat Click here
