New DVD delves into the beauty and fragility of Auckland’s harbours

27 May 2009

A little known yet wonderfully complex web of life exists in the beautiful harbours and estuaries of Auckland.

But it’s an ecosystem under threat from contaminants and sediment flowing untreated straight down kerbside stormwater drains, or off cleared land and down creeks to the sea.

The 20 minute DVD, presented by TV’s Judy Bailey and produced by the Auckland Regional Council (ARC), takes a looking glass to the shellfish, snails, worms, fish, rays and unique birds in our harbours and estuaries and that rely on clean water.

The DVD was produced to promote a greater awareness of the stormwater and sediment problem by showing what we stand to lose.

Building materials such as zinc roofs and copper spouting, waste materials from cars, and waste from urban activities such as factory yards are some of the sources of the contaminants building up in our waterways.

Meanwhile sediment – essentially earth – is flowing off exposed land that is being developed or has been deforested, and is silting up our waterways.

Chair of the ARC’s Environmental Management Committee, Dianne Glenn, says that sediment and contaminants affect water quality and in turn the habitats upon which aquatic life relies.

“While much is being done by the ARC, local councils, community groups and individuals such as developers to improve the quality of the water entering our harbours and estuaries, there is a growing problem, and we all have a part to play to improve the situation,” says Cr Glenn.

“We need to ensure that what goes down Auckland’s kerbside drains is clean and free from contaminants like oil, paint and even carelessly discarded cigarette ends. Soap suds from car washing should never drain off driveways into the stormwater system. Wash your car on the grass or use a commercial carwash.

“Similarly, when development occurs, or forest is cleared, huge amounts of the exposed earth can go into the harbours and estuaries affecting and even changing habitats.

“The overall message from this DVD is that our harbours and estuaries are full of a dazzling array of life. While much good work is being done to keep it that way, it is the responsibility of each and every one of us to protect this wonderful asset.”

Copies of the DVD are available free of charge to schools and community groups, and to individuals for $5 (including postage).
