Response for project 198909802: Salmon Studies Id Rvrs Npt
Comment on proposed FY 2006 budget
Renewed funding is desired for this project for FY2006 at the current $429,841 amount. This budget has been frozen at $429,841 since the last provincial review. However, this project has had to cut back on necessary work to stay within this amount. To accommodate this work, the proposed adjusted budget for FY2006 would be $484,771. There have been increases in health care, inflationary and fuel surcharge increases for vehicles, an increase in the repairs and maintenance of equipment that needs replacement, inflationary increases in office and storage rentals, and escalating personnel costs (includes added safety requirements). Additional costs are being incurred to respond to ISRP requests. Additional funding is also requested for the ISRP recommended parentage assignment work (Memorandum to NPCC on ISRP 2003-8, 2/6/2004, Appendix B - Evaluating Reproductive Success of Hatchery Origin and Natural Origin Spring and Summer Chinook Salmon for the Idaho Supplementation Studies) at $454,826 annually. This is a cooperative project which involves the Nez Perce Tribe, Idaho Department of Fish and Game, U. S. Fish and Wildlife Service, and the Shoshone-Bannock Tribes.

How is this project consistent with subbasin plans?
Salmon River Sub-basin: The project is consistent with and implements Aquatic Strategies 1A1, 1A2, and 1A3 (Mgt. Plan page 20). These strategies relate to Objective 1A; to increase the numbers of spawning adults to achieve recovery goals. This project is using supplementation to evaluate the rebuilding of extirpated populations and enhancing existing populations. Aquatic Strategies 2A1, 2A4, and 2A7 (Mgt. Plan pages 23-25). These strategies relate to Objective 2A; improve understanding and definitions of small populations. This project is building population information on 31 individual streams. Aquatic Strategies 3A1, 3A2, and 3A3 (Mgt. Plan page 25). These strategies relate to Objective 3A; address data gaps to measure freshwater survival and productivity. This project is evaluating egg to smolt survival and population productivity. Aquatic Strategies 3C1, 3C2, 3C3, 3C4, and 3C5 (Mgt. Plan pages 25-27). These strategies relate to Objective 3C; address data gaps to measure progress towards delisting and full recovery. This project quantifies abundances, determines stream specific SARs and productivity, evaluates population productivity, and measures reproductive success. This project adds to information needs as listed in Mgt Plan (Table 13, pg 120). This project is listed as an on-going primary program for coordination with proposed research due to its established index sites and/or trend data for population status (RM&E Aquatics, 4.3.1; pp 63-77) Clearwater River Sub-basin: The project is consistent with and implements Anadromous Fish Species Strategies 1.A.1 and 1.A.2 related to Problem 1.A. (Mgt Plan pg 14) to increase the number of naturally spawning adults by supplementation and 2.B.4 related to Problem 2.B. (Mgt Plan pg 18) to develop monitor indices by determining juvenile abundances, conducting redd counts and carcass surveys: 3.C.2 related to Problem 3.C (Mgt Plan pg19) to develop knowledge of interactions between hatchery and wild fish by conducting juvenile hatchery and natural survival, origins of escapement, and genetic evaluation of adults: 3.D.1 related to Objective D (Mgt Plan pg 21) for natural population augmentation and rebuilding, reintroduction and research.
How do goals match subbasin plan priorities?
The Salmon Subbasin Management Plan prioritization process utilizes an environmental framework approach to prioritization and does not address biological characteristics explicitly. They do acknowledge this shortcoming: “The weakness in this approach, however, is that the focus on environmental limiting factors and problem statements does not adequately address or balance biological limiting factors within the prioritization framework.” The plan caveats the entire prioritization process with this request: “Filling key data gaps will further improve the accuracy of prioritization processes. ….. The general agreement among the Technical Team members was that to conduct a scientifically valid prioritization, certain information that is not currently available would be needed (e.g., basic egg to fry, parr, presmolt, and smolt survival information, population-specific adult abundance and productivity key performance data).” The ISS project goals scientifically address all data gaps listed above and will be invaluable in providing data for the prioritization process.
The ISS is a long-term study initiated in 1992. This is a cooperative project which involves 31 streams and four agencies – Nez Perce Tribe, Idaho Department of Fish and Game, U.S. Fish and Wildlife Service, and Shoshone-Bannock Tribes. It is entering Phase III which will be completed by 2014. The project has undergone numerous reviews by the ISRP. Additional funding is requested to complete genetic evaluations as recommended by the ISRP.
