200733200 - Mititgation of marine-derived nutrient loss in the Boise-Payette-Weiser subbasin

Sponsor: Idaho Department of Fish & Game

Budgets: FY07: $351,037 | FY08: $360,084 | FY09: $367,509

Short description: The project replaces marine derived nutrients using salmon carcasses and salmon carcass analogs in the Boise-Payette-Weiser subbasins. Aquatic and terrestrial effects of nutrient treatments will be monitored using isotope and lipid analysis.

ISRP final recommendation: Fundable


This is a basic research project with implications to similar high elevation headwater areas. The project should generate new knowledge on trophic chains from salmon carcasses. This is a well-thought out and unique proposal that has a high likelihood of providing new and immediately useful information for both the research and management communities. The proposal relates this work to objectives in the subbasin plan and other regional programs. The proposal does not directly relate the work to other projects with BPA funding. Collaboration with IDFG, U.S. Forest Service, and Idaho Power Company are noted. The personnel are well qualified. The project reflects a nice mix of personnel from the management agency (IDFG) and from the academic community. Plans for information transfer include publication in peer-reviewed journals, but efforts to share lessons learned and successful results to others in the region on a timelier basis should be identified. The sponsors responded very effectively to ISRP questions about how this work differs from other recent work and provided justification that this work is still needed. The work would be done in a set of conditions (blocked area, nutrient-poor batholith, and bull trout) that differ significantly from those of ongoing nutrient addition evaluations. The response indicates that enough study sites are available, but the sample size question was not completely addressed. Instead, other studies where statistically significant results were obtained were cited. Before fieldwork is implemented the sponsors should conduct a sample size/power analysis to ensure that an adequate number of sites will be sampled to have a high probability of detecting biologically meaningful treatment differences.
