NON-STATIONARITY AND THE NEED FOR AN EXPANDED FRAMEWORK FOR FLOW-ECOLOGY RELATIONSHIPS
Non-stationarity in hydrologic and ecological conditions represent an emerging, key challenge to e-flows science as currently practiced. As e-flows transitions from a sole restoration focus to a broader adaptation focus, flow-ecology relationships grounded in the natural flow regime concept will continue to provide the foundation of e-flows applications. Clear specification of flow-ecology relationships is critical to shaping justifiable management expectations and attaining e-flows success. Advancing e-flows science under non-stationarity requires that e-flows science develop a more dynamic “process-based” understanding of hydro-ecological relationships, to allow for more dynamic and responsive management. Implicit in this approach is the need to clearly identify scale of application in e-flows applications, insofar as methods and tools available to quantify flow-ecology relationships present scale-dependent tradeoffs in hydro-geomorphic modelling precision and in ecological responses. At present, ecological response variables are typically static descriptors of low frequency state variables over large spatial extents. However, other ecological variables, including ecological rates and species traits, can and should be employed to extend the spatial and temporal domains of an evolving e-flows science.
