PNAMP Habitat Status and Trends
Monitoring
Management Question:
Are the Primary Habitat Factors Limiting the Status of the
Salmon and Steelhead Populations Increasing or Decreasing?
Project Goal:
Develop a Coordinated Habitat Monitoring Program that
Addresses Key Regional (Priority) Monitoring Questions and
Develop Study Designs of Sufficient Quality and Quantity to
Determine the Status of LCR Habitat Conditions.
Note: Statement doesn’t refer to fish performance…separate
process? Coordination required.
PNAMP Habitat Status and Trends Monitoring
5 –Objectives:
1. Document and prioritize habitat monitoring goals, objectives, and
habitat indicators for management agencies in the LCR.
2. Determine the adequacy of existing monitoring programs to meet
priority habitat monitoring goals and potential for reducing gaps by
improving monitoring program coordination, data sharing, and data
translation.
3. Describe possible monitoring designs, sampling frames, protocols, and
analytical tools to meet needs of priorities identified in Objective 1 and
refined in Objective 2.
4. Habitat monitoring recommendations for the LCR based on regional
priorities established in Objective 1, cost-effectiveness, and a range of
budgets.
5. Develop process for monitoring implementation, data management,
reporting mechanisms, and adaptive management of monitoring.
Conceptual Framework
…the array of local instream conditions found within fluvial systems are created
and constrained by predictable hydrologic and geomorphic processes…
…these processes operate hierarchically….
....large scale processes constrain the expression of processes at smaller
scales…
…riverine systems can be divided into discrete scales that reflect the
relationship between hydrologic and geomorphic processes and local river
features…
…local river features determine biological assemblage…

Worldview (WQ, Resource Management, Fish Centric)
Terminology
Meaningful Spatial Units- (Watershed, Catchment, Valley Segment,
Network, Reach etc.)
Measurements and Metrics taken over space and time
Appropriate Analysis Tools (GIS, Satellite, Survey Crews)
Accuracy and repeatability of analysis
Ability to pool monitoring resources (cost effectiveness)
Knowledge of linkages between metrics, stream conditions, Fish
Performance
Ability and Time required to detect change
Organization of data, analysis and presentation

NPPC Framework- EDT Habitat Database
1. Worldview- Fish Centric
2. Metrics – In or Near-Channel
3. Methods- Measured, Opinion, Inferred
4. Scale- Reach (Tributary to Tributary)
5. Temporal- Point Estimate
6. Repeatability- Varies by stream
PNAMP Habitat Status and Trends Monitoring
Are the Primary Habitat Factors Limiting the Status of the Salmon and Steelhead
Populations Increasing or Decreasing?
So What Are These?
LCSRP- Limiting Factors (In-Channel)
1. Passage Obstructions
2. Stream Flow
3. Water quality
4. Habitat/Complexity
5. Substrate and Sediment
6. Large Woody Debris
7. Channel Stability
8. Riparian Function
9. Floodplain Function
Threats (Landscape)
Habitat threats are the human‐derived activities that have created and/or are
perpetuating the habitat limiting factors
1. Water Withdrawals
2. Barriers
3. Forest Practices
4. Agriculture/Grazing
5. Urban and Rural Development
6. Mining
7. Channel Manipulations
8. Recreation
Does M&E Need to Account for All Limiting Factors?

Example Framework
Hierarchy
1.Landscape- Areas that have indirect connections with the river channel through contribution of
surface water and groundwater, sediments and other materials (catchment area beyond the
floodplain and riparian zone)
2. Floodplain- Areas within the floodplain and riparian zone
3. Stream Channel- Areas at or below bank-full conditions
Scale(s)
Select based on limiting factor or threat being addressed
