Evan Engber of Bioengineering Associates and his crew examine the banks of the lower Garcia River on the Galliano property before beginning a riparian restoration project. Note the car body at left in the picture, which may indicate where the former bank line was before it eroded. Note the large tipped-over alder, which is visible in later photos after restoration (Pictures #7-8. Photos courtesy of Rixanne Wehren, Vivian Bolin and Evan Engber. September 1996.

Evan Engber of Bioengineering Associates consults with Natural Resource Conservation Service staff at the base of what appears to be a ten foot high eroding bank on the Galliano property, which is the target of this restoration project. Photos courtesy of Rixanne Wehren, Vivian Bolin and Evan Engber. Sept. 3, 1996.

This photo is a zoom back on the area shown in Pictures #1-2 and shows that bank erosion extends for more than 100 feet. Photos courtesy of Rixanne Wehren, Vivian Bolin and Evan Engber of Bioengineering Associates. September 1996.

This photo shows the bank on the Galliano property after a toe trench was dug, willows planted and riprap placed to add stability. Notice the black pipe for drip irrigation above the boulders. See Picture # 5 to see the bio-engineering project after soil cover has been distributed and flow deflected to the base. Photos courtesy of Rixanne Wehren, Vivian Bolin and Evan Engber of Bioengineering Associates.

The riprap and plantings are shown here on September 12, 1996 with soil burying the willow sprigs and irrigation applied. The flow of the river appears to have been deflected to water willows in the toe trench. See Picture #6 to see this same site in February 2001.

The tree directly in front of the fishing lure is the same as that shown in Picture #1, #6-#8. Note that there is a continuous wall of willows sprouting from the bio-engineering project. Photos courtesy of Pat Higgins. February 2002.

This April 2003 photo shows the same piece of large wood depicted in #1 and #6. Note that alders and willows are maturing and that a gravel bar now also deflects current away from the formerly vulnerable bank on the Galliano property. Photo courtesy of Craig Bell.

The vegetation from the adjacent bioengineering project have now grown over the large downed alder visible in Picture #1. The roots and trunks of these planted trees lock around the large wood and cement the entire bank structure. Photo courtesy of Craig Bell.
