Habitat Effectiveness Monitoring Subgroup
Report CSMEP Chris Beasley Nick Bouwes Tim
Copeland Steve Katz Ian Parnell Charlie
Paulsen Keith Wolf Bonneville Workshop July
20-21, 2005 The task Apply the DQO to
effectiveness monitoring Steps 1-5 generate a
question Steps 6 7 strategy to identify an
optimal design
2

• Steps 1-5 were intended to generate the design
  parameters for monitoring
• Identified questions
• To what degree have restoration and/or protection
  actions affected key habitat attributes?
• To what degree have these actions affected the
  subject population?
• Are particular classes of projects more effective
  than others (e.g., scale of effect v. cost and/or
  time)
• What are the mechanistic connections between
  recovery actions, key habitat attributes and fish
  population responses?
• Unfortunately key requirements of the DQO process
  were not available for incorporation
• Management Input
• Eg step 2
• Identify principal study questions (?)
• Define alternative actions
• Combine the principal study question and
  alternative actions into a decision statement and
  state each decision in terms of whether to take
  action.
• Organize multiple decisions into an order of
  priority

3

• The absence of management input made it unclear
  how to proceed to steps 6 7
• Applied a new process to help compose
• generic utility
• Clarification of the question
• What are all the species, down to life-history
  type and gender, of interest?
• What is the spatial boundary of the population
  for which inferences will be made?
• What is the population response variable you want
  to evaluate to determine whether a change has
  occurred?

• Picked an example Lemhi
• The Lemhi Habitat Conservation Plan (HCP)
• Heavily impacted with agriculture diversions and
  consequent passage issues
• Plan for a series of phased in reconnection
  projects in the upper main stem
• 10-17 tributary reconnection projects
• 4 year round reconnection, seasonal for the rest
• Phased in over the next 35 years
• 4 completed by 2010
• 10 completed by 2025

5

• Clarified questions for the Lemhi
• Have the actions implemented under the Lemhi HCP
  expanded the distribution of rearing juvenile
  salmonids within the basin and increased the
  density of rearing juvenile salmonids relative to
  average mainstem densities by X over 30 years
  (with some precision) when the number of
  spawners, natural disturbances, climate
  indicators, and habitat conditions not-impacted
  by the actions have been accounted for?
• Have the actions implemented under the Lemhi HCP
  produced at least a 100 increase in the number
  juvenile spring Chinook salmon leaving the Lemhi
  River in 30 years (/- X) when the number of
  spawners, natural disturbances, climate
  indicators, and habitat conditions not-impacted
  by the actions have been accounted for?
• Have the relative magnitudes of the seasonal
  migration pulses and size distribution of
  migrating Chinook juveniles leaving the Lemhi
  River changed over the life of the Lemhi HCP?
• Have the actions implemented under the Lemhi HCP
  increased the abundance of bull trout in
  reconnected tributaries relative to unconnected
  tributaries by X over 30 years (with some
  precision)?
• Have the actions implemented under the Lemhi HCP
  increased parr-smolt survival (X /-specified
  precision) of juvenile spring Chinook salmon
  leaving the Lemhi River in 30 years when the
  number of spawners, natural disturbances, climate
  indicators, and habitat conditions not-impacted
  by the actions have been accounted for?
• Have the returns of adults Chinook salmon to the
  Lemhi basin increased X (/-specified precision,
  see VSP criteria developed by ICTRT) over the
  period of the Lemhi HCP?

Cost
Top-Down based on per project costs and
contracting history for previous
projects. Bottom-up based on cost per unit
time per person multiplied by the sample sizes
identified in the plans.

• What are the opportunities to economize these
  designs?
• Is one of these plans good enough?
• Does this plan get me what I need?
• Why should I not just pick the cheapest design?
• If I have a fixed amount of money, what parts of
  each design can I compromise on?
• If so what performance do I lose for the dollar
  saved?

16

• What inference is good enough?
• Comparisons
• Less replication
• Low A B relative to C - Before and After
• Greater Replication
• Mid Reconnected vs unconnected trib. Areas -
  Before and After (narrow data)
• High Reconnected vs unconnected trib. areas -
  Before and After (broad data)
• The Client has to decide if this is good enough

• If so what performance do I lose for the dollar

• Usually this means statistical performance
  quality of inference, power, precision, accuracy
  per dollar.

18

• Why collect so much other data?
• (more data more , no?)
• Use diverse data to explain/subtract other
  sources of variability
• Filter out noise to leave treatment effects

• How to conceptually link the design data to the
  test?
• There are numerous potential analytical designs
• w/ different relationships between data tests
• BACI design. Low design Develop a linear
  predictor model and evaluate relative importance
  of treatment Paulsen and Fisher (2004)
• Asymmetric BACI design - Underwood (1994)
• Randomized Intervention analysis - Carpenter et
  al. (1989)
• Picking the right design remains a research
  effort

The analytical design defines the relationship
between all the variables in the monitoring data
and how differences constitute a test. Different
relationships can be traded to economize based on
priorities established in steps 1-5 of DQO. This
is a continuing research project. There is still
a need for policy/ management to step in and
inform where appropriate.

• Consequences of altered response design
• Create a time series with 8 components
• Fit with increasing number of monitored
  variables to a selected sub-segment

to ask? The Client has to answer not the tech
