Click on image to enlarge (142K).This photo shows Redwood Creek in its lower reaches during winter conditions with alder not yet leafed out.

The alder, willow and shrubs lining the banks will provide much improved cover and shade when they leaf out in spring. Undercut banks under alder roots often create refuge areas for juvenile and adult steelhead. Photo provided courtesy of Golden Gate National Recreation Area.

These relatively undisturbed upland areas act as a water filter and also allow absorption of part of the winter rains into ground water storage.
