Climate change, drought, habitat alterations, and increasing water demands are leaving less water available for streams of the Pacific Northwest and for fish like salmon. As water levels drop, some small streams become fragmented, transforming from a ribbon of continuous habitat into a series of isolated pools. Fragmented streams may pose a serious threat to salmon. For example, juveniles that become stranded in small pools are at increased risk to overheat, starve, or be consumed by predators. Healthy salmon populations can cope with fragmentation and recover from a bad drought-year. However, many salmon populations are endangered and face long-term drought. Land and resource managers are increasingly finding...

Climate change has the potential to magnify existing problems in conservation, such as invasive species and disease. This threat is particularly severe in the Klamath Basin, where the fish parasite Ceratonova shastais making national headlines for killing salmon, and invasive trout have extirpated populations of native trout. The Klamath Basin is slated for one of the largest restoration projects in human history involving the removal of 4 mainstem dams. The success of this massive effort will likely depend on how climate, disease, and invasive trout combine to affect fisheries. However, there is currently no data available to incorporate these important interactions into conservation planning. This dearth of information...

Oregon’s Upper Klamath Basin is one of the warmest watersheds in the Pacific Northwest. Despite its naturally warm waters, the basin supports abundant redband trout. These are some of the largest-bodied trout in the entire U.S., and are a culturally and economically important species, providing the last remaining subsistence fishery for the Klamath Tribes and drawing recreational anglers. The ability of this coldwater species to survive in one of the region’s warmest watersheds could hold valuable clues for conservation in the face of warming global temperatures, which represents one of the biggest threats to North America’s coldwater fish. Previous research has found that redband trout rely heavily on spring-fed...
