  1. A spatial framework formanaging Hawaii’s aquatic resources: Improved conservation and restoration opportunities in a changing world Dana Infante infanted@msu.edu Department of Fisheries and Wildlife, Michigan State University

  2. www.fishhabitat.org Protect, restore and enhance nation’s aquatic communities through partnerships Objectives • Conduct an objective condition analysis of fish habitats • Identify priority habitats for conservation, enhancement, or restoration

  3. 2010 Hawaiian River Condition Assessment: Built from a landscape approach Landscape factors Habitat Condition index Good Biology Poor Landscape-scale disturbances • Agriculture, urban land use Roads • Former plantations Dams • Ditch intersections, length Quarries • Injection wells TRI Sites • NPDES sites

  4. Spatial framework and database • National HydrographyDataset (1:24,000 NHD) • Local and network catchments delineated using ArcHydro • Confluence to confluence reaches • Breaks implemented based on elevation • Assessment data and other variables have been attributed to each spatial unit Network catchment Local catchment Reach Reach Reach

  5. Flexibility and benefits of a spatial framework Moku Network catchments Island Ahupua’a Island Local catchments and reaches, NHD

  6. Current applications • NFHAP coastal condition assessment for Hawaii • “Assessment of coral and fish disease in three priority watersheds and their relationship to land-based pollution loads,” R. Oram, G. Aeby, T. Work • Plans to compare results with Hawaii Watershed Atlas

  7. Plans to refine the assessment • Integrate additional landscape-scale disturbance data • Golf courses • Refined fragmentation statistics • Downstream disturbances measures • “Calibrate” scores using biological data Target reach

  8. Next step • “Managing the Nations Fish Habitat at Multiple Spatial Scales in a Rapidly Changing Climate” • USGS-funded project to determine vulnerability of fish habitat to projected changes in climate and land use • Project builds on elements of current condition assessment • Goal: Conduct a similar type of assessment in Hawaii, using current conditions scores as a base • Consider freshwater, marine and terrestrial systems • “Integrated” vulnerability assessment • Currently working with PICCC, USGS to coordinate a planning meeting

  9. Thank you! • Gordon Smith • Dan Polhemus • Bob Nishimoto • Glenn Higashi • Jim Parham • Malie Beach Smith • Gary Whelan • Doug Beard • Andrea Ostroff • NFHAP Science and Data Committee

  10. Gary Whelan (MDNRE), Doug Beard (USGS), Andrea Ostroff (USGS) • NFHAP Science and Data Committee “More people working for more fish”

  11. Disturbance variables: Urban and point source

  12. Disturbance variables: Former plantation, fragmentation, ditches, agriculture, 303D listings

  13. Benefits of a spatial framework • Summarizes amounts, types, and locations of natural and anthropogenic system influences • Integrates data and results of other studies across different scales • Allows decision makers to easily compare regions, identifying priority areas for protection, enhancement, or restoration • Establishes a consistent reporting framework Reach • A Hierarchical Spatial Framework and Database for the National River Fish Habitat Condition Assessment, In Review.
