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.

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.

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.

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.

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.
