  1. Michael Liquori, VTAC Chair and others… The VTAC Committee: Developing Guidance for an Alterative Regulatory Pathway to the Anadromous Salmonid Protection Rules

  2. Introduction

  3. ASP Rule Section V • The 2009 Anadromous Salmonid Protection (ASP) Rules • Section V allows for site-specific riparian design • This approach is voluntary

  4. VTAC Objectives • To establish principles, guidelines and procedures • Broaden Incentives • Establish permitting efficiencies & reduce regulatory uncertainty

  5. Incentives to Use 14 CCR § 916.9(v) • Landowners will have increased flexibility to manage riparian zones based on site-based needs (vs. a fixed, prescriptive standard).

  6. VTAC Outreach Survey

  7. VTAC Survey Responses n=123 responses

  8. VTAC Survey Summary

  9. VTAC Survey Summary

  10. VTAC Survey Summary

  11. VTAC Survey Summary

  12. Survey: Take-Home Messages • Widespread agreement that site-based riparian management can be used where it is justified • Need increase level of certainty for extensive use of Section V process • Need successful pilot projects & guidance to demonstrate to landowners that approach can work

  13. Framework for Riparian Design

  14. Framework for Riparian Design • Relative importance of riparian function inputs for forming aquatic habitat & improving water quality • Transport of riparian inputs to downstream channels

  15. Geomorphic Influences

  16. Types of Section V Projects

  17. Additional Key Factors

  18. Large Wood Placement

  19. Thinning to Affect Recruitment 200 trees/acre Unthinned 300 trees/acre 100 trees/acre

  20. Litter Inputs

  21. Biotic Diversity & Nutrients “Riparian stands dominated by deciduous vegetation (overstory and understory) within 10-20m of the stream may increase biomass of consumers, including fish, as a result of nutritious litter inputs and terrestrial invertebrate subsidy” (Allan et al. 2003, Richardson et al. 2004, Wipfli & Musselwhite 2004, Hoover et al. 2007)”

  22. Biotic Diversity & Nutrients • a sufficient number of nitrogen-fixing deciduous trees distributed at key locations within the stream network; • a sufficient number of riparian canopy gaps that support primary and aquatic macroinvertebrate production while balancing effects on other riparian functions. (Wilzbachet al. 2005; Kiffney and Roni 2007; Modenke and Ver Linden 2007; Poor and McDonnell, 2007; others)

  23. Fuel Hazard Reduction “Dense stands of trees in the Angora SEZ likely contributed to the rapid [fire] spread upslope to Angora Ridge…” -Murphy et al. 2007

  24. VTAC Guideline Document • Criteria for site suitability • Site-based objectives • Treatment option alternatives • Data necessary to justify proposed actions • Administrative procedures for agency approvals
