Ground Water and Ecosystems Restoration Division The “Plus” sustainable economies flood reduction carbon sequestration species diversity recreation timber/wood production safe water supply liveability tourism Ecosystem Restoration Actions Research to evaluate ecosystem benefits of restoration actions Research to translate ecosystem benefits into economic benefits Restoration Plus Watershed Managers and Partners NRMRL GWERD NRMRL STD MAHA Region
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
6
Ground Water and Ecosystems Restoration Division Impacts of Stream Restoration on Nitrate Processing, Hydrology, Biology and Sediment Transport at Mine Bank Run in Baltimore, MD US EPA NRMRL GWERD Maryland District USGS Water Resources Division Institute of Ecosystem Studies Baltimore County Department of Environmental Protection and Resource Management Baltimore County Parks Department
7
Ground Water and Ecosystems Restoration Division Mine Bank Run Before Restoration
8
Ground Water and Ecosystems Restoration Division Comparison of restoration technologies to be employed at Minebank Run BEFORE Point Bars Pools Riffles AFTER Bank stabilization techniques Energy dissipating structures Stream channel relocation Relative effects on: a.Water Quality ( nutrient processing) b.IBI c.Sediment Transport
9
Ground Water and Ecosystems Restoration Division Bank Stabilization: Re-shaping Stream Corridor Restoration Handbook Organic Soils Saturated Zone? Organic Soils? Saturated Zone
10
Ground Water and Ecosystems Restoration Division Shallow/deep monitoring wells Piezometer well nests Shallow/deep monitoring wells Mine Bank Run Transect Design
11
Ground Water and Ecosystems Restoration Division Mine Bank Run Stream restoration plans and selected transect locations
12
Ground Water and Ecosystems Restoration Division Hypothetical relationship between carbon and denitrification among stream features Increasing Organic Matter Increasing Denitrification Activity RipRap Wing Vane Pool Riffle Re-shaping Slope After Point Bar Before
13
Ground Water and Ecosystems Restoration Division Hydrologic and Geomorphic Controls on Riparian Ecosystems in the Great Basin of Central Nevada David G. Jewett, U.S. EPA, ORD, NRMRL, Ada, OK Mark L. Lord, Western Carolina University, Cullowhee, NC Jerry R. Miller, Western Carolina University, Cullowhee, NC Jeanne C. Chambers, USDA Forest Service, Reno, NV
14
Ground Water and Ecosystems Restoration Division
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
23
Ground Water and Ecosystems Restoration Division Stable Channel Good IBI Balanced Sediment Transport Improved Water Quality Benefit>Cost Unstable Channel Poor IBI Sediment Transport Poor Water Quality We are hereOur Destination
