Objectives of Subtidal Goals Report

Regional 50-year vision to improve subtidal habitats

Non-regulatory, interagency, collaborative approach

Science goals to address data gaps

Protection goals to maintain quality and function

Specific restoration targets based on phased approach

Audience: Resource managers, academics, non-profits, etc.

Ecosystem Services

Definition:

The benefits people derive, either directly or indirectly, from ecosystem functions (e.g., harvest, sense of place, recreation, visual aesthetics, nutrient cycling, primary production)

Ecosystem services identified for the SF Bay Subtidal Goals Project include only those that are not directly extractive or destructive of habitat.

Project Vision

  • Achieve a net improvement of the San Francisco Bay’s subtidal ecosystem over the next 50 years through restoration, science, and protection.

  • To achieve this improvement, the project proposes:

  • Increasing the quantity of desired but currently limited habitats;

  • Emphasizing support of native species;

  • Increasing our understanding of the physical and biological

  • processes that affect subtidal habitats and species.

Guiding Principles

  • Subtidal and intertidal habitats

  • Precautionary approach

  • Science, restoration, protection

  • Avoids prioritization of habitats

  • Adaptive management approach

  • 10 year review in 2020

  • Examples of Goals

  • Science Goals

  • Develop mechanisms to adapt to climate change.

  • Understand the factors controlling the development of oyster beds.

  • Determine suitable methods for protecting mudflats and beaches.

    Protection Goals

  • Protect existing eelgrass habitat through no net loss to existing beds.

  • Consider the potential ecological effects of contaminated sediments when developing, planning, designing and constructing restoration projects or other projects that disturb sediments.

  • Restoration Goals

  • Focus on quantifiable

  • and regionally-specific targets

  • Increase native eelgrass within 8,000 acres of potential suitable subtidal area through a phased pilot project approach.

  • Promote pilot projects to remove artificial structures and creosote pilings at targeted sites, in combination with Living Shoreline techniques.

  • Reduce habitat fragmentation and increase connectivity across upland, intertidal, and subtidal habitats.

Intrinsic Subtidal Connection to Wetlands


Transition zones on both edges

Transition Zones on Both Edges

Upland transition

Subtidal transition

Wetland edges: sand bars, shell beds, kelp and eelgrass fringe, rocky intertidal

Living Shorelines: A soft bioengineering approach


Marilyn latta north bay watershed association novato ca june 3 2011

Living Shorelines: Issues for study in SF Bay

  • Scale: what acreage is needed to slow wave action?

  • Suitability: must be matched to site conditions

  • Permitting: fill considerations in the subtidal zone

  • Monitoring: functional connections between habitats

  • Pilot: test effectiveness thru experimental designs
