A one-dimensional daily averaged water temperature model was used to simulate Klamath River temperatures for two management alternatives under historical climate conditions and six future climate scenarios. The analysis was conducted for the Secretarial Determination on removal of four hydroelectric dams on the Klamath River. In 2012, the Secretary of the Interior will determine if dam removal and implementation of the Klamath Basin Restoration Agreement (KBRA) (Klamath Basin Restoration Agreement, 2010) will advance restoration of salmonid fisheries and is in the public interest. If the Secretary decides dam removal is appropriate, then the four dams are scheduled for removal in 2020.
Understanding the distribution and gaps in distribution for invertebrates that serve as prey items for waterbirds in the Great Basin is proving to be a successful way of understanding how prey availability may change as climate-induced changes to salinity in wetlands vary across the Great Basin. The molecular work for this project is coupled with a concurrent study of Great Basin wetlands, water chemistry, climate models, and waterbird use of the area to provide a robust picture of current and future conditions.

Predicting and Managing Climate Change Impacts on Semi-Arid Land Wetlands, Migratory Birds, and Their Prey: An Integration of Remote Sensing, Molecular Genetics, Hydrology, and Environmental Modeling
Predicted climate impacts on arid U.S. Great Basin wetlands will alter their number, distribution, and quality (e.g., salinity). The scarcity and isolation of these wetlands make them essential not only to wildlife but to ranchers, farmers, and urban areas that rely on their ecosystem services. Great Basin wetlands are important habitats for migratory birds at high volumes, but they become concentrated mineral brines at low volumes, narrowing waterbird food resources as salinity rises. Thus, many resource managers need to answer two questions: How will climate change affect migratory bird species dependent on climate-sensitive wetlands? How should management strategies balance human-consumer uses of these water...
