to prevent significant adverse impacts to the primary

limiting factors that affect listed anadromous salmonid

species in a planning watershed”

• Rules lack SPATIALLY-RELEVANT GUIDANCE for where factors are limiting

• Otherwise,

SERM PrinciplesSERM PrinciplesSERM Principles

PrinciplesPrinciples

• SERM achieves riparian goals through spatially-explicit, context-specific objectives

Established by actual site conditions, not rule assumptions


•SERM treatments are based on a Transparent, Science-Based Rationale

Uses the best-available technical tools and

empirical data


• SERM institutes a rigorous 4-Tier Accountability System

– Transparent Objectives

– Performance Standards

– Monitoring

– System-Wide Adaptive Management

Next StepsNext Steps

• Simplify Rule Language: Refer to Guidance Documents – similar to County Regulations throughout

California

• Develop SERM Design Manual– Collaborative Effort

– Living Document

– Updates Require Board Approval

Wood Supply– wood budgets

– site-based source distance curves

– surveys of streamside riparian forest composition

– forest growth modeling

– LWD accumulation types???

– Wood supply maps


Thermal Loading– analysis of seasonal vs perennial streams

– reach to watershed scale thermal loading (stream size, orientation, topographic shading, flow, vegetation shading, etc.)

– analysis of canopy density etc. of existing riparian stands and role of harvest

– role of stream type/groundwater/hyporheiccharacteristics on heating potential


Erosion Controls– analysis of bank erosion potential

– upstream sources and sinks

– equipment exclusion

– legacy mitigation (e.g. roads, landings, etc)

– local drainage pathways (swales, roads, etc)

Why is SERM the RIGHT SolutionWhy is SERM the RIGHT Solution

It’s supported by a 4-Tier

Accountability System


•Applied using available data and tools, –Does not require significant

development of data or tools by state agencies.

•Subject to existing standards and protocols for agency review


•It’s cost effective

•Does not depend on extensive State-funded programs.
