But also pinch yourself. You will need to check your sense of reality! We are about to tell you that Consent

The ARC, after all their machinations, the stalling, the flim flam, the deferences to higher authority as a con-      (09) 298 6507

case there were breeding birds. However, PDC wished to proceed with removing the three 1ha trial plots.               Graeme Kerr
ARC responded, “prove there are no adverse effects, with a bird survey”.

Have you heard of the Banded Rail?
It is a rather nice wading bird found throughout the South Pacific.
Commit that name to memory. Google some images.

Footprints were found, thought to be of the Banded Rail. No birds. Just footprints. A few pages of reporting          EDITOR:
later and that group of footprints had been transformed into at least ten pairs of birds!                             Richard Archer
ARC sternly assured the PDC that removal of any mangroves would surely annihilate these mythical pairs,               (09) 298 8567

Inlet Banded Rail could not move to another location and survive! We couldn’t make this stuff up! Six
months of wheel-spinning delays ensued as ARC pushed for further surveys at rate payer expense, which, to             COMMITTEE:
their credit, PDC fought.                                                                                             Anne Archer
What really baffles us is why the preservation of mangroves could be justified on the basis of maintaining the        Andrew Bell

tidal wading birds, such as herons, oyster catchers, pied stilts and others we know and love, would flourish.         Jan Bell
Could it be it’s more about mangroves than birds?!                                                                    Vanessa Murch
PDC deserves your admiration. In the face of boundless ARC perversity they have maintained their resolve,             Gwenda Purdy

chipped straight into the tide, without delay! You may have seen the recent picture of the local Kamatua
blessing the new machine, which can remove 6ha per day!                                                               Margaret Williams
We actually wonder whether we would still be waiting had it not been for the pending Super City deadline              Erica Wilson
forcing the ARC to resolve all outstanding consents. Welcome assistance from an unexpected quarter!                   Neville Wooderson
If ARC approves the trial plot removal expeditiously, PDC plans to restore a further 6ha before the bird
breeding season in July. ARC approval is an elusive thing, but we are hopeful!

                                      Were you one of the over 400 to enjoy the PIPS canoe day last year? We hope so as it was a truly
                                      fantastic occasion for families and individuals from Papakura and beyond. In fact even the Google
                                      satellite turned up and took an aerial shot for posterity, which you can see by typing Youngs Beach
                                      Reserve into Google maps, selecting satellite and zooming in. Spot the canoes on the water!
                                      There will be appearances by the Cook Island vaka, Maori waka and our redoubtable Coastguard
                                      team will again be displaying their facilities and giving scenic rides. (By then the PDC sincerely hopes
                                      to be able to give you the contractors’ mangrove removal start date and we should soon have a hectare
                                      or two more of mangrove-free open water for you to enjoy). Fingers crossed for glorious weather again.

                            January 2009 contains a set of conditions that must be complied
                            with in order for mangrove removal work to be approved.
                            Before removal work can begin, baseline studies, which record
                            specific physical and biological conditions as they exist in the Inlet,
                            are a requirement for the permit.
