Bexley Wetland

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.

Riverbank restoration

Post-quakes there is still plenty of demolition underway in Christchurch.

Meanwhile, the plants are making the most of any and all opportunities.

And the central city is also undergoing a major restoration of the banks along the Avon River (Te Papa Ōtākaro).

Natural Environment Recovery Programme

Post-earthquakes, a natural environment recovery plan has been developed by Environment Canterbury (and others). This is part of the Recovery Strategy for greater Christchurch. Biodiversity is one of the aspects considered.

There is introductory and summary material here, or go straight to the main report here.
