4. Ground Water and Ecosystems Restoration Division Research to evaluate ecosystem benefits of restoration actions

5. Ground Water and Ecosystems Restoration Division How can we evaluate the effectiveness of stream restoration? Metrics Index of Biological Integrity (IBI) Ecosystem Services (denitrification, carbon sequestration,etc.) Stream Geomorphic Stability Stream Flow Sediment Transport Water Quality

15. Comprise less than 2% of land area in the Great Basin Contain a large percentage of the region’s biodiversity Impacted by stream entrenchment and loss of valuable habitat Riparian and wet meadow ecosystems

16. Ground Water and Ecosystems Restoration Division

17. Depth to WT vs Vegetation Type

18. Ground Water and Ecosystems Restoration Division 1)Hydrogeological conditions leading to meadow formation 2)Sensitivity of existing vegetation to changes in water table depth 3)Challenge traditional restoration approaches because of unique groundwater/surface water dependency. 4)What techniques will work? What metrics can be applied? Factors to consider when evaluating management/restoration alternatives

19. Ground Water and Ecosystems Restoration Division Research to translate ecosystem benefits into economic benefits

20. Ground Water and Ecosystems Restoration Division How can we estimate the costs/benefits of stream restoration? Benefits: Existing Metrics-Can we value the change? Index of Biological Integrity (IBI) – Benthic and Fish communities improve Ecosystem Services (denitrification,etc.)-Water quality improvements, lower pollutant load downstream Stream Geomorphic Stability-Protect infrastructure, land, maintain aquatic environment Sediment Transport-Protect in stream and downstream habitats Costs :Accessible and Defined

21. Ground Water and Ecosystems Restoration Division Current Reality: Willingness to Pay

22. Ground Water and Ecosystems Restoration Division Partnerships between ORD and Canaan Valley Institute The Highlands Action Program model for implementing sustainable resource management decisions in the MAHA. Research to develop tools for cost/benefit analysis of restoration Develop restoration prioritization methodologies including cost/benefit
