Within the Salmon subbasin, we have implemented a habitat and population status and trends monitoring project in the South Fork Salmon River (SFSR) watershed and habitat action effectiveness evaluation in the Lemhi River watershed. These initiatives are joined through the application of a watershed model (QCInc 2005) that views fish vital rates (survival productivity, abundance, and condition) as a function of the quantity and quality of available habitat. These functions are constructed using both coarse (e.g., Geographic Information Systems (GIS)) and fine (e.g., reach) scale habitat measures. Once validated via the collection of empirical data within habitat classes, the model provides a statistical framework to assess the effects of different classes of habitat actions on life- stage specific vital rates (productivity/survival and condition) of anadromous and resident salmonids.
This particular model has also been used for Steelhead in the Middle Fork John Day (Pete McHugh, ELR), and Chinook and Steelhead in the Entiat (Shubba Pandit, Terrraqua).
