  1. MAV Potential Natural Vegetation (PNV) Mapping Spring Steering Committee Meeting June 8, 2011 Tom Foti, Charles Klimas, Jody Pagan, Amy Keister

  2. PNV Mapping: The Problem • Vast portions of the Lower Mississippi Alluvial Valley have been converted to agriculture • Hydrology has been changed at the landscape and local levels • The pre-settlement vegetation is no longer the appropriate restoration target • “Potential Natural Vegetation” refers to the native plant communities best adapted to establish and persist as the predominate cover on the landscape under the current hydrologic regime

  3. PNV Mapping: The Problem 1927 Flood Current Levee System

  4. PNV Mapping: The Problem • Goal • Support ecosystem restoration planning • Support impact assessment and mitigation calculations • Objectives • Map and describe PNV communities at a scale useful for both landscape analysis and site-specific restoration • Use an HGM-based classification system to support functional assessment using HGM guidebooks for the region

  5. PNV Mapping: Where • Arkansas sub-basins • Bayou Meto-Grand Prairie (Memphis District, CE) • Western Lowlands (EPA/State) • Boeuf-Tensas (Vicksburg District, CE) • St. Francis (EPA/State) • Louisiana sub-basins • Tensas (USFWS Joint Venture) • Ouachita-Boeuf-Macon Ridge (USFWS Joint Venture) • Mississippi • Yazoo Basin (Walton Family Foundation/ USFWS Joint Venture/CE)

  6. PNV Mapping: How • Identify and describe appropriate communities for specific combinations of site factors: • Hydrology/hydrography • Geomorphology • Soils

  7. PNV Mapping: How • Approach • Assemble or develop required spatial data • Classify and describe plant communities based on field studies and literature • Develop additional data as needed and specify mapping criteria • Produce and document PNV maps

  8. PNV Mapping: How • Approach • Assemble or develop required spatial data

  9. PNV Mapping: How • Approach • Assemble or develop required spatial data

  10. PNV Mapping: How • Approach • Assemble or develop required spatial data • Ducks Unlimited Flood model

  11. PNV Mapping: How • Approach • Assemble or develop required spatial data • Ducks Unlimited Flood model • National Hydrography Dataset

  12. PNV Mapping: How • Approach • Assemble or develop required spatial data • Ducks Unlimited Flood model • National Hydrography Dataset • Geomorphology Saucier 1:250k

  13. PNV Mapping: How • Approach • Assemble or develop required spatial data • Ducks Unlimited Flood model • National Hydrography Dataset • Geomorphology Saucier 1:250k • Soils – Parish level

  14. PNV Mapping: How • Approach • Assemble or develop required spatial data • Classify and describe plant communities based on field studies and literature

  15. PNV Mapping: How • Approach • Assemble or develop required spatial data • Classify and describe plant communities based on field studies and literature

  16. PNV Mapping: How • Approach • Assemble or develop required spatial data • Classify and describe plant communities based on field studies and literature • Develop additional data as needed and specify mapping criteria

  18. PNV Mapping: How • Approach • Assemble or develop required spatial data • Classify and describe plant communities based on field studies and literature • Develop additional data as needed and specify mapping criteria

  19. PNV Mapping: How • Approach • Assemble or develop required spatial data • Classify and describe plant communities based on field studies and literature • Develop additional data as needed and specify mapping criteria • Produce and document PNV maps

  20. PNV Mapping: How • Approach • Assemble or develop required spatial data • Classify and describe plant communities based on field studies and literature • Develop additional data as needed and specify mapping criteria • Produce and document PNV maps • 118 processes

  21. PNV Mapping: Result & Applications • Goal • Support ecosystem restoration planning • Support impact assessment and mitigation calculations • Objectives • Map and describe PNV communities at a scale useful for both landscape analysis and site-specific restoration • Use an HGM-based classification system to support functional assessment using HGM guidebooks for the region

  22. PNV Mapping: Result & Applications Rethinking Flood Control? 1927 Flood Current Levee System

  23. PNV Mapping: Result & Applications Rethinking Flood Control? • Arkansas sub-basins • Bayou Meto-Grand Prairie (Memphis District, CE) • Western Lowlands (EPA/State) • Boeuf-Tensas (Vicksburg District, CE) • St. Francis (EPA/State) • Louisiana sub-basins • Tensas (USFWS Joint Venture) • Ouachita-Boeuf-Macon Ridge (USFWS Joint Venture) • Mississippi • Yazoo Basin (Walton Family Foundation/ USFWS Joint Venture/CE)
