Lahontan Cutthroat Trout – Oncorhynchus clarkii henshawi

• Status – Endangered
• Estimated numbers – Unknown, but currently occupy approximately 482 miles of habitat. The species is also found in five lakes, including two small populations in Summit and Independence Lakes. Self-sustaining populations of the species occur in 10.7 percent of the historic stream habitats and 0.4 percent of the historic lake habitats.
• Population trend – Decreasing
• Location – Lahontan basin of northern Nevada, eastern California, and southern Oregon
• Why are they under threat – The severe decline in range and numbers is attributed to a number of factors including; hybridization and competition with introduced trout species, loss of spawning habitat due to pollution from logging, mining, and urbanization, blockage of streams due to dams, channelization, de-watering due to irrigation and urban demands and watershed degradation due to overgrazing of domestic livestock.
