Monitoring Results

Grebe Monitoring Results

Plumas Audubon has been working to analyze how lake users, reservoir managers, downstream water users, local wildlife and grebes influence one another. We hope that our work will lead to increases in suitable nesting habitat for the grebes in ways that do not negatively impact lake users. All of the current lakes in our study area are man made reservoirs, thus a focus during these surveys is observing the effect that lake level management has on available nesting habitat, reproductive success rates, and depradation on both adult grebes as well as their eggs.

During the 2010-2011 monitoring seasons, Eagle Lake and Lake Almanor were surveyed for nesting Aechmophorous grebes. In 2012 Lake Davis and Antelope Lake were added to the study areas, Mountain Meadows Reservoir was added in 2013.
