PLENARY SESSION IV: Aquatic Systems/Watersheds

The watersheds of the Sierra Nevada are often viewed as the source of a large proportion of California's cleanest water. They are also home to an array of vertebrate and invertebrate wildlife and plants. Because of the scale of water development in the range and the variety of contemporary and historic uses made of the landscape, the aquatic systems are under varying degrees of threat. Understanding the role of water and land uses and management on the well-being of aquatic systems and their watersheds is critical to protecting and conserving these systems throughout the Sierra Nevada. Similarly, investigating the relationships among aquatic species and with their environment is important in understanding where and when to intervene when it is essential to protect native fauna and processes. This session will combine presentations on conserving native fauna, effects of actions in the watershed on these fauna, and developing ways to assess the cumulative effects of actions in the watershed on watershed and aquatic processes.
