Event Title

Side channels along the lower Cedar River, Washington in the context of a regional floodplain assessment

Presentation Abstract

Floodplains are ubiquitous features of lowland river systems in the Salish Sea basin that present management challenges because of their ecological and social value. Regional assessment can be used to develop normative standards of floodplain function and condition, but benefit from field-based investigation for validating results and quantifying their precision. A case study from the lower Cedar River in Washington compares field survey of side channels to LiDAR-derived mapping . These methods can complement each other for delineating side channels and evaluating functional differences in terms of connectivity and community composition. The combined methods provide a baseline for future monitoring but also insight into the regional potential for increasing off-channel habitat along floodplains that is critical for imperiled salmon.
