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

Princilpal Study Question Alternative Action
Are there significant levels of lead in floor dust at a childrens residence? Remove the children from the residence
Are there significant levels of lead in floor dust at a childrens residence? Initiate a clean-up removal of lead-based paint.
Are there significant levels of lead in floor dust at a childrens residence? Take no action.

  • 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?

   
4
  • 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?

6
  • 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?
  • Information Needs
  • Distribution of juvenile salmonids
  • Density of juvenile salmonids
  • Abundance of juvenile Chinook
  • Size distribution of juvenile Chinook
  • Parr-smolt survival of juvenile Chinook
  • Abundance of Bull trout
  • Trend in Adult Chinook
  • Number of Spawners

  • 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
    Not monitoring technicians.

  • If I have a fixed amount of money, what parts of

  • If so what performance do I lose for the dollar
    saved?
  • 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.

to ask? The Client has to answer not the tech
