par·a·digm [ˈperəˌdīm]

A philosophical and theoretical framework of a scientific school or discipline within which theories, laws, and generalizations and the experiments performed in support of them are formulated.

Webster-Merriam online dictionary

For the past 24 years, Trinity River Restoration Program scientists with specialties in geomorphology, hydrology, biology, and ecology have worked to mutually impact management actions with the mission of restoring anadromous populations of Chinook Salmon, Coho Salmon, and Steelhead through recovery of river ecosystem function. Adaptive management has played a central role in providing context to scientific debate and implementation as data is received and disseminated.  However, challenges remain regarding implementation of adaptive management, particularly in gaining consensus across Program technical staff, the Trinity Management Council, and the public. Within the Program we see examples of “applied scientific paradigms” shifting because of scientific information that we’ve either learned on the Trinity River, learned from other systems, or applied on the Trinity River. Examples span disciplines, but prominently have included changes to the amount, locations, and strategies of sediment augmentation, realized and proposed changes to flow and temperature management, and evolution of channel rehabilitation philosophies and practices.

The 2024 Science Symposium asks presenters and attendees to help answer this question: “How can we better apply findings from scientific inquiry to push boundaries and re-define paradigms of river restoration?” The Program has conducted science for more than two decades, and the recently adopted science plan provides a blueprint for science implementation in the coming years. How can guidance from the science plan leverage two decades of learning to maximize adaptive management potential for achieving programmatic objectives? We hope to gather, learn from each discipline, consider each management action, and focus the Program forward into new paradigms of restoration.
