  3. Overview • Need to better assess mitigation success • Need web-based GIS to manage project information • Give public access to information • Link to other databases

  4. Goals • Make it a program and project management tool for water board manager and staff • Make it a planning tool to provide better watershed context for local entities to plan for priority development and conservation areas • Make it a permit application tool to guide project proponents on mitigation and restoration

  5. Project Map

  6. Project Map

  7. Wetland Tracker Data AnalysisAugust 2006 –- December 2007

  8. 45 Projects Resulting in habitat loss to: 11.5 acres and 6,125 linear feet. Acres Linear Feet Restored: 12 17,082 Created + 10 + 1,089 TOTAL: 2218,171 Enhanced 145 8,663 Preserved +10 + 1,203 TOTAL: 1559,866 GAINS Improvements Wetland Tracker as a 401 Condition in Region 2

  9. Estuarine: Brackish Salt Pond Tidal Depressional Seep Riparian Riparian Vernal Pool WETLAND TYPES in Wetland Tracker:

  10. Project Types That Required Compensatory Mitigation. (Total = 36)

  11. Riparian Linear Feet and Acres Lost and Gained

  12. ACRES: Estuarine (acres)

  13. Project Review Findings • Estuarine and depressional habitats had highest replacement ratios; • Vernal pools had highest impacts to existing habitats and the lowest replacement ratios; • Riparian habitats were impacted 3 times more than other habitats; replacement ratios were mid-range using linear feet and very low for acres.

  14. Next Steps To insure the accuracy of Wetland Tracker as a tool: • Review and correct wetland tracker forms • Follow up on late or inaccurate forms • Conduct field verifications • Analyze 2008 data to determine if 2006-07 trends continue or differ

  15. Management Decisions • Develop general permit for maintenance activities • Avoid and minimize impacts to vernal pools and riparian systems • Inform policy development
