Restoring floodplains and riparian forest: Lessons from the Cosumnes River

Naturally-functioning floodplains provide a variety of ecosystem services, including habitat for diverse species.  California’s rivers are highly altered, with levees that disconnect floodplains, dams that alter flows, and land use practices that have destroyed most than 90  percent of riparian...

Characterizing Hydrologic Variability of the Cosumnes River Floodplain

Natural riverine and floodplain ecosystems are adapted to highly variable hydrologic regimes, which include periodic droughts, infrequent large floods, and relatively frequent periods of inundation. To more effectively manage water resources and maintain ecosystem services provided by rivers and...

Priming the productivity pump: flood pulse driven trends in suspended algal biomass distribution across a restored floodplain

1. Chlorophyll a (Chl a) distribution across a 0.36 km2 restored floodplain (Cosumnes River, California) was analysed throughout the winter and spring flood season from January to June 2005. In addition, high temporal-resolution Chl a measurements were made in situ...

Perennial Pepperweed Infestation on the Cosumnes River Experimental Floodplain A Report to the California Bay-Delta Authority

Riparian floodplains present a unique challenge for restoration management, in that these are, by definition, dynamic, constantly changing ecosystems. As restoration projects are initiated and progress through time, both native and invasive species can become established. During the initial...

Patterns of regional and local riparian plant diversity in the California Sacramento - San Joaquin Valley

The widespread degradation of riparian ecosystems requires that we more fully understand patterns of plant diversity at multiple scales to inform restoration and conservation efforts locally and regionally. We analyzed the distribution of riparian plant diversity in California's Sacramento - San...

A Multi-Proxy Approach to Examining Land-Use Change Effects on Steelhead Trout and Coho Salmon in NW California

Historically, juvenile and spawning adult steelhead trout and coho salmon were found in abundance in the Navarro Basin of NW California. However, the numbers of juvenile steelhead and spawning adults have declined greatly over the past 100 years, while coho salmon rearing and spawning is now...
