The Lahontan cutthroat trout (Oncorhynchus clarkii henshawi) is a freshwater fish species native to the Lahontan Basin in Nevada, California, and Oregon. The estimated remaining population is approximately 6,000 individuals but decreasing. The main threats to the Lahontan cutthroat trout are habitat degradation, water diversions, competition with non-native fish species, hybridization with rainbow trout, and climate change impacts such as reduced stream flows and increased water temperatures. Conservation efforts focus on habitat restoration, streamflow management, and captive breeding programs.
