Saltmarsh Restoration and Management

This paper describes marine and estuarine wetlands in the Canterbury area and evaluates the current status of marshlands surrounding the Avon Heathcote Estuary. It presents a concept plan, developed by the Waste Management Unit of the Christchurch City Council for the restoration of marshes in a 90 hectare area currently used for stock grazing. We present current research on the plant and animal communities within the remnant marshes including seasonal patterns shown by invertebrates, birds and fish. We will identify some of the scientific information necessary before marsh restoration can proceed and consider some of the management (planning) options in developing and restoring marshlands.
