Title: Sacramento River Biological Indicators Project |

Abstract/Description: Operational definitions and measurable indicators of ecosystem health are needed to prioritize restoration or rehabilitation efforts, and steer systems toward desired endpoints. The restoration goal for an ecosystem is not a single state, but a range of ecosystem states and processes that occur over time in an ecosystem that supports native species and responds to dynamic environmental regimes representative of natural conditions that applied before systems were massively altered by humans. Increasing our understanding of the linkages between physical structure and processes and biotic responses in Central Valley river systems is critical to improving our ability to predict the effects of various restoration or rehabilitation actions on biological populations of interest and in developing effective indicators to monitor and test the results of implementing such actions (the focus of this study).
Our underlying conceptual model is shown in Figure 7 of Golet et al. (2003). In this model, natural watershed inputs (e.g., water, sediment, nutrients) and anthropogenic alterations to these inputs influence important physical processes. These processes determine the physical and chemical attributes that affect habitat structure and connectivity in river-riparian-floodplain systems. Species abundance and distribution and trophic structure are directly affected by these habitat attributes. There is a need to develop indicators of ecosystem processes, such as nutrient cycling and food web interactions, that can complement more commonly used indicators based on ecological patterns. To meet this need, we are conducting a pilot study to examine, at a range of sites along the Sacramento River, several potential indicators that integrate over various spatial and temporal scales.
