Introduction to ER - Part 3 - Norway - ppt
- 1. Introduction to nature restoration Part 3 Carrying out a restoration project Restoration methods A little extra focus on soils and alien species... Astrid B. Skrindo Astrid.Skrindo@nina.no Date: Autumn 2024
- 2. All parts must be included in a restoration project 2 Society's framework conditions Practical knowledge and experience Ecology
- 3. Nature restoration is a process 3 NOW! Baseline/ Starting point. Map, describe how the area/ The area is now. AFTER! Evaluate the aftermath. This often needs to be done several times over a longer period. BEFORE! Is there knowledge about BEFORE the disturbance/interventi on. If so: Map this and use as a REFERENCE SYSTEM TAKE ACTION! What restoration measures are possible? Select and initiate restoration measures! Before? Reach Measures After GOAL! Formulating concrete goals is the key to success!
- 4. Just to make it a little more complicated... 4 https:// www.forsvarsbygg.no/ contentassets/ 1b24a6a488754283995 d7844f0dcbc56/ handbok-i-okologisk- restaurering.pdf
- 5. The goal depends on the starting point, the measures and the ecological conditions 5 Example : Removal of road Remove the asphalt Remove the asphalt, do further restoration measures
- 6. Restoration methods • Completely different restoration methods for different ecosystems, different species and different scales... • Above: A review of revegetation methods 6
- 7. What is the connection between REVEGETATION and nature restoration? 7 Here: Defines it as the vegetation phase of a restoration project...
- 8. Revegetation methods • Soil and terrain treatment • Natural revegetation • Supply of nutrients • Adding plant materials • So • Plant • Moving vegetation peat --- • Removing trees and shrubs • Removing alien species • Fencing/screening Combination of methods is almost always necessary - Natural revegetation from the surroundings will always happen...

Revegetation methods • Soil and terrain treatment • Natural revegetation from urban topsoil • Supply of nutrients • Adding plant materials • So • Plant • Moving vegetation peat --- • Removing trees and shrubs • Removing alien species • Fencing/screening Illustr: E. Kongsbakk https://hdl.handle.n et/11250/2833981 • Removing the top masses • Store the topsoil separately • Place the top soil loosely on top of the subsoil
- 11. The result can be so good... Photo: AB Skrindo
- 12. It will never be better than the content of the top masses... Burot Solidago canadensis Rumex sp But also like this... Photo: AB Skrindo
- 13. Revegetation methods • Soil and terrain treatment • Natural revegetation • Supply of nutrients • Adding plant materials • So • Plant • Moving vegetation peat --- • Removing trees and shrubs • Removing alien species • Fencing/screening Do commercial seeds have anything to do with nature restoration?
- 14. Example: Erosion in Iceland Step 1: Fertilise + seed commersial gras-seeds Step 2: Natural revegetation from the surroundings
- 15. Local (?) seeds! From high From NIBIO seeds

- 19. Revegetation methods • Soil and terrain treatment • Natural revegetation • Supply of nutrients • Adding plant materials • So • Plant • Moving vegetation peat --- • Removing trees and shrubs • Removing alien species • Fencing/screening Reynotria japonica
- 20. Revegetation methods • Soil and terrain treatment • Natural revegetation • Supply of nutrients • Adding plant materials • So • Plant • Moving vegetation peat --- • Removing trees and shrubs • Removing alien species • Fencing/screening Are measures for threatened nature having t he desired effect? (arcgis.com)
- 21. Choice of revegetation methods • If possible: Find a comparable ecosystem • Define goals and milestones • Choose the revegetation method that facilitates natural succession with as little work as possible.
- 22. Nature restoration is a process 22 NOW! Baseline/ Starting point. Map, describe how the area/ the area is now. AFTER! Evaluate the aftermath. This often needs to be done several times over a longer period. BEFORE! Is there knowledge about BEFORE the disturbance/interventi on. If so: Map this and use as a REFERENCE SYSTEM TAKE ACTION! What restoration measures are possible? Select and initiate restoration measures! Before? Reach Measur es After GOAL! Formulating concrete goals is the key to success! How did it go? REMEMBER AFTERCARE AND EVALUATION!! !
- 23. A little about alien species and mass handling 23 Does it have anything to do with nature restoration?
- 24. Regulations on alien organisms: §1 The purpose of the regulation is to prevent the introduction, release and spread of alien organisms that cause, or may cause, adverse effects on biodiversity.
- 25. Illustrative example: Gravbergknapp (Phedimus spurius) (SE) outcompetes axveronica (Veronica spicata), vulnerable (VU) on the Red List (2021) in the selected habitat type open shallow limestone soil in the boreonemoral zone Photo Siri Lie Olsen

- 27. 27 12.08.2025 Mass handling and due diligence... §Section 18...shall act with due care to prevent the activity from having consequences for biodiversity... • Must have knowledge... • Take preventive measures... How careful is careful enough §24 ... (4) Before moving loose masses or other masses that may contain alien organisms, the person responsible shall, to a reasonable extent, investigate whether the masses contain alien organisms that may entail a risk of adverse consequences for biodiversity if dispersed, and take appropriate measures to prevent such risk, such as the use of masses from other areas, covering, burying, heat treatment, or delivery to a legal waste facility.
- 28. Conduct an environmental risk assessment • Characteristics of the species • Propagation: By seed • Seed bank: Surviving more than 50 years • Vegetative survival: Roots survive several years • The surroundings • Nature that could be threatened? YES! Selected habitat type hay meadow in the neighbourhood without lupine... • Is there more in the area? No, there isn't. Just here on the roadside. • The activity • When to dig? Summer • Where will the excavation take place? Parts of the road • Other activities? - • Conclusion • Combat? YES! • Limit the spread? YES, if control does not work • Nothing at all? No -does NOT hold Exam ple: Hagelupin
- 29. Don't forget: Whatever is in the topsoil before the intervention, it will also be there when you lay it down...
- 30. Sometimes it does NOT matter! OTHER TIMES IT DOES MATTER

This often needs to be done several times over a longer period. BEFORE! Is there knowledge about BEFORE the disturbance/interventi on. If so: Map this and use as a REFERENCE SYSTEM TAKE ACTION! What restoration measures are possible? Select and initiate restoration measures! Befor e? Reach Measu res After GOAL! Formulating concrete goals is the key to success!
