A Representing all bars in the sample reach (not the row total).

1 Early successional (< 1" diameter stems) to woody (< 1" diameter stems).

2 Number gravel bars with grasses/sedges.

3 Number of large gravel bars out of total number.

4 Bars with no vegetation, easily disturbed.

5 Land use surrounding the site as possible reason for gravel deposition (30-meter resolution TM satellite imagery).
