Abstract: Bull trout (Salvelinus confluentus) in the Klamath Basin are at a high risk of extinction as a result of altered ecological processes, which have reduced habitat quality, increased water temperatures, and exacerbated habitat fragmentation. Population isolation has reduced gene flow among populations and resulted in population bottlenecks and hybridization with brook trout (Salvelinus fontinalis) have all resulted in the need to conserve genetic diversity within and among bull trout populations in the Klamath Basin. We will discuss collaborative efforts to restore ecosystem processes and management activities for bull trout conservation. This is an attempt to re-establish life history characteristics that will enhance geneflow among populations in the Sycan Core Area and potentially adjacent Core Areas. The approach we used incorporates hypothesis testing for management strategies against potential management responses and to monitor climate impacts at the watershed scale. The information presented may enhance selecting future management strategies which will require balancing uncertainty inherent in projections of future climate impacts and the risks associated with different management options.
