Bexley Wetland, at the mouth of the Avon River (just before it joins into the Avon-Heathcote Estuary) is almost unrecognisable after the 2011 earthquakes. Liquefaction was substantial in this area and many homes adjacent to the wetland were destroyed.

The wetland used to support a mixture of salt and fresh water wetland vegetation, due to the combination of river water, freshwater springs, and tidal flow via the estuary. There were some especially nice salt meadow areas, but the site looks very different now.
