Reviews and recommendations

This information was not provided on the original proposals, but was generated during the review process.

Recommendation:
Fundable only if response is adequate
Date:
Aug 2, 2002

Comment:

This proposal builds on work begun under one-year innovative funding to examine the impact of regulation flows on riparian cottonwoods in the Yakima and Kootenai River Basins. The use of remote-sensing tools and field sampling methods for further studies of riparian cottonwoods in other alluvial reaches of the Columbia River Basin was the "proof of concept" aspect of the innovative project. This is worthwhile research project that should provide recommendations for normative changes in flow regimes in the Yakima that maximize recruitment of cottonwoods. The scientific background is extensive and well written. The project is related to other projects and regional programs. Objectives, tasks and methods are well written and complete. The sponsors need to address the following:
  1. The sponsors need to provide better evidence of the linkage of changes in flow regimes, geomorphic processes, and cottonwood recruitment to changes in stream habitat and in the aquatic community, especially the fish community. What kinds of habitat changes are to be expected from improved cottonwood recruitment? Perhaps the research needs an empirical component that specifically addresses the relationship between changes in cottonwood communities and changes in the channel and aquatic community. At a minimum a much more comprehensive discussion of the relevance and benefits of this research to fish communities is needed.
  2. How do differences in surface elevations (A and B in Figure 2 and Objective 2, Task a) relate to cottonwood recruitment? What relative values of A and B are desirable and what ones are not?
  3. In discussing the results of the innovative project some empirical evidence needs to be presented supporting the contention that the current flow regime disrupts recruitment processes (page 26). A more thorough and concise discussion of the kinds of flow management options that could improve recruitment would be beneficial.
  4. Objective 4 related to model development needs to be expanded. What kinds of models are being considered? What are the critical parameters in the models? Exactly how will the data collected in the previous three objectives be used in model development?
  5. The sponsors propose additional studies to extend research to other important reaches (with distinct flow regimes) within the Yakima. Observation of variation among reaches of the Yakima Basin is claimed to be critical to the extension of research findings to other alluvial reaches of the Columbia Basin. The sponsors claim "Since cottonwoods are a keystone species in the biodiversity of riverine corridors, our findings will be critical to a number of large flow-regulated rivers in the western United States. Hence, our results will not only be significant for managing regulated flows in the Naches and Yakima rivers, they will also be relevant where flows are regulated on alluvial reaches elsewhere in the Columbia River Basin." If additional studies are necessary to extend the research to other important reaches within the Yakima Basin is it likely that the results will be relevant elsewhere?
  6. The project needs an M&E plan.

Action Agency/NMFS RME Group Comments:

HABITAT ACTION EFFECTIVENESS RESEARCH SUBGROUP -- Does the Proposal meet RPA Objectives?

They have one stated objective that suggests a potential experimental base upon which to ask the RPA 183 relevant question of action effectiveness: can regulated flows be modified to promote recovery of riparian cottonwood ecosystems? However, the sponsors do not propose to measure any listed salmonid survival rates or other variables directly relevant to 183, nor would this be possible in their Flathead control area. As such, 35062's direct relevant to 183 is very limited.

Elements the proposal is lacking.

Measurements of salmonid survival rates, variables directly relevant to 183, and site location to meet these objectives are lacking.

Means and Opportunities to Strengthen Proposal.

This is a clear, focused and well-supported proposal. The focus is on the ecology of the trees with some superficial references to how that in turn affects habitat for anadromous fish. It is unclear if this project can be modified to address questions regarding the affects of riparian improvement projects on fish.

ISRP Remarks on RME Group Comments:

The ISRP's comments, especially question 1, are consistent with RM&E comments.


Recommendation:
High Priority
Date:
Oct 24, 2002

Comment:

This project was recently reviewed by CBFWA as a within year request. CBFWA recommended to the Council that this project should be funded. CBFWA recommends that the project investigators coordinate with the regional fish and wildlife managers and related projects (e.g., Project Number 2002001100, 199705900, etc.) to better facilitate regional ecological based assessment efforts.
Recommendation:
Fund
Date:
Nov 5, 2002

Comment:

Fundable (qualified). Disagree with CBFWA's High Priority ranking; this is of lower priority. The project represents good science conducted by well-qualified investigators. The scientific background is extensive and well written. The project is related to other projects and regional programs. Objectives, tasks and methods are well written and complete. This proposal builds on work begun under one-year innovative funding to examine the impact of regulation flows on riparian cottonwoods in the Yakima and Kootenai River Basins. The use of remote-sensing tools and field sampling methods for further studies of riparian cottonwoods in other alluvial reaches of the Columbia River Basin was the "proof of concept" aspect of the innovative project. This project should provide recommendations for normative changes in flow regimes in the Yakima that maximize recruitment of cottonwoods, and the sponsors make a convincing case based on published literature that normative changes in flow regime will improve fish habitat. However, the project does not provide direct measurement of habitat and fish community changes associated with flow regime change. This unmeasured applicability to stream habitat and aquatic communities is a distinct shortcoming of the proposal.

The response repeats many of the assertions from the original proposal. Some members of the sponsors' proposed "review team" appear to have close connections to project personnel, raising a question of objectivity.

Statement of Potential Biological Benefit
Indirect. Research riparian cottonwoods and geomorphic responses to regulated flows in the Yakima Basin, compare responses to an unregulated reach of the Flathead River with the objective of enhancing flows to restore riparian habitats in the Columbia Basin

Comments
The sponsors need to provide better evidence of the linkage of changes in flow regimes, geomorphic processes, and cottonwood recruitment to changes in stream habitat and in the aquatic community, especially the fish community. This could be valuable research but does not respond to a specific RPA action.
