EVC/Bioregion Benchmark for Vegetation Quality Assessment Murray Fans bioregion EVC 821: Tall Marsh Description: Wetland dominated by tall emergent graminoids (rushes, sedges, typically in thick species-poor swards. Competitive exclusion in core wetland habitat - of optimum growing conditions for species tolerant of sustained shallow inundation. Occupies wetlands usually associated with anabranch creeks. Soils are almost permanently moist. Dominant species are tolerant of relatively deep and sustained inundation, but not total immersion for any sustained period.
