Description

The Cosumnes River is the only unregulated river on the western slopes of the Sierra Nevada. Because it remains undammed, it experiences the seasonal overbank flooding that was once a common feature of rivers in California's central valley. This flooding supports the natural growth of riparian and floodplain vegetation, which in turn serves as home to an astounding array of wildlife. More than 250 bird species, over 40 fish species, and approximately 230 plant species have been identified on the approximately 4,700 acre reserve. These include various species of egrets and herons, sandhill cranes, stilts and avocets, phoebes and flycatchers, and yellow and Wilson’s warblers. The property was designated as an ecological reserve by the Fish and Game Commission in 2003, and includes the Dillard, Arno, and McFarland Units.
