Monster Seminar JAM - Emerging Riparian Perspectives and Challenges in the Pacific Coastal Ecoregion
Dr. Robert Naiman, School of Aquatic and Fishery Sciences, University of Washington
Riparian zones, intimately located at the terrestrial and aquatic interface, possess important ecological characteristics controls on the routing of materials, energy, and information as well as influences on habitat and biodiversity. My presentation focuses on riparian systems associated with rivers along the Pacific Coast of North America where I, my colleagues and students, have been conducting research for nearly 25 years. Firstly, I will present a broad-based overview of what is known about key ecological characteristics associated with riparian systems, especially with respect to system-scale heterogeneity, biodiversity, tree production, interactions between large woody debris and plant succession, and the ecological consequences of marine-derived nutrients for riparian soil and plant communities. Secondly, I will address three essential research directions for the coming decade: the role of epiphytes in maintaining riparian functions, the determination of environmental flows for riparian systems, and the juxtaposition of marine-derived and atmospherically-derived nutrients in maintaining riparian functions. Finally, I will conclude with a brief discussion of how a better evaluation of riparian zones as dynamic ecological systems can improve basin-scale management in the Pacific Northwest and the good and services they provide.
