In this course, we use a watershed perspective to learn about the ecology of streams and rivers, with an emphasis on the coastal region of the Pacific Northwest. The general topic is well supported by a variety of theoretical concepts, and these will be used as the foundation for developing a regional knowledge of aquatic communities and the associated riparian zones. A strong emphasis is placed on ‘natural' systems. Topics addressed include general hydrology and geomorphology, along with detailed discussions of system classification, riparian zones, roles of animals, hyporheic processes, suspended and benthic organic matter, trophic ecology, system metabolism, decomposition, biogeochemical cycles, and microbial ecology.

There are two weekend field trips (Skagit River and Hoh/Queets River), one field trip during regular class hours to a local stream, and extensive laboratory exercises on stream organisms and quantitative tools. In lab, you will be given the opportunity to develop hands-on skills in the identification of a wide variety of stream organisms and their basic life history traits. The goal of this course is to produce a ‘work-ready' individual who can speak with authority about the components and dynamics of river ecosystems.
