The condition of floodplain vegetation in Zone G improved with increasing flow volume in the range assessed. The greatest improvements were estimated for the 1500 GL scenarios (scores range from 0.32-0.34), particularly for the 'b' and 'c' operational scenarios. Scores for the 350 GL scenarios (range 0.29-0.30) and 750 GL scenarios (range 0.30-0.31) also showed some improvement relative to the 'Reference' scenario score (0.28).
