“Every timber operation shall be planned and conducted

to prevent significant adverse impacts to the primary

limiting factors that affect listed anadromous salmonid

species in a planning watershed”

• “sediment load increase where sediment is a primary limiting factor;”

• “thermal load increase where water temperature is a primary limiting factor;”

• Etc.

Why is SERM the RIGHT Solution?Why is SERM the RIGHT Solution?

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

• Otherwise,

ALL FACTORS are Limiting

SERM PrinciplesSERM PrinciplesSERM Principles

PrinciplesPrinciples

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

Established by actual site conditions, not rule assumptions

PrinciplesPrinciples

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

Uses the best-available technical tools and

empirical data

PrinciplesPrinciples

• SERM institutes a rigorous 4-Tier Accountability System

– Transparent Objectives

– Performance Standards

– Monitoring

– System-Wide Adaptive Management
