View looking east off Highway 1 Bridge at grassy uplands interspersed with mixed hardwood-conifer forests while alder dominates the riparian zone of Greenwood Creek in the foreground. Note pampas grass at the center of the photo along the roadway. Photo provided by Pat Higgins, February 15, 2002.

View looking west off Highway 1 Bridge shows coniferous forest forming the riparian overstory and alder tree immediately next to Greenwood Creek. Some Eucalyptus trees can be seen at right also. Photo provided by Pat Higgins, February 15, 2002.

View looking south east off Highway 1 Bridge with alder trees in the riparian zone of Greenwood Creek but conifers growing on the slopes back from the stream and up the canyon. Photo provided by Pat Higgins, February 15, 2002.

This photo shows a wood jam on Greenwood Creek that is comprised mostly of hardwood and small diameter conifers. These pieces do not provide the same habitat quality as mature conifers which would also last hundreds of years in the stream. Photo provided by Pat Higgins, February 15, 2002.

This close up of the Greenwood Creek gravel bar shows willows sprouting everywhere. Willows on gravel terraces have their greatest success in recruitment during low flow years. This vigorous willow colonization was enabled by very low and moderate flows in 2001-2002. Photo provided by Pat Higgins, February 15, 2002.

Large alder trees in the foreground provide most of the immediate riparian vegetation of Greenwood Creek, but coniferous trees occur on the slopes above. Invasive species are in evidence at this site with pampas grass at right in the foreground and English ivy covering the steep slope above the creek at the center of the photo. Photo provided by Pat Higgins, February 15, 2002.

This photo shows English ivy running up riparian alders and willows. The ivy may eventually strangle or out-compete by shading these trees and cause their mortality. This is not beneficial for proper riparian function of Greenwood Creek. Photo provided by Pat Higgins, February 15, 2002.

Looking down from the shoulder of Highway 1 at Greenwood Creek just up from the mouth. The windswept coast discourages conifer colonization but conifers occur immediately upstream as the canyon blocks the wind. One very large chunk of old growth sized large wood is embedded in the stream. Photo provided by Pat Higgins, February 15, 2002.
