Figure 5. An enlargement of an area on the 1996 photograph showing three dredge scars that may have been formed with differing intensities of dredging. The intensity of dredging appears to decrease from scar 1 to scar 3.
Figure 6. An enlargement of the same area on the 1998 photograph showing differing amounts of revegetation in the three scars. The amount of revegetation appears to increase from scar 1 to scar 3.
