Will the Tāmaki Estuary lose the last of its shorebirds?

After surveyors interrupted the start of the breeding season at Point England I was worried about what someone might be planning. With fantastic support from Auckland Council we have been looking after the endangered New Zealand Dotterel that nest in the paddock for several years now.

It’s been hard work but the dog walkers in particular have been awesome, and we have had some real highs like the fledging of our first dotterel chick and regular visits from one of New Zealand most critically endangered birds the shore plover.

The paddocks have cows which keep the grass short, but the birds do not come for the grass. Migratory birds like bar-tailed godwits fly from the other side of the world to feed in the expansive mud flats of the Tamaki Estuary. When the tide comes in all the wading birds seek refuge above the high tide line. But if you look on Google you will see there are no roosting areas along the margins of the Tamaki. There is some green but it comes with trees, dogs or rugby balls. So the majority of the white faced herons, royal spoonbill, South Island oystercatchers, variable oystercatchers, New Zealand dotterel, banded dotterel and pied stilts all make there way to the paddocks. For most of the year there are small ponds in the paddock so when a harrier flies over and sends hundreds of birds into the air its like your’e in a David Attenborough documentary.

So this was released today. A bill to turn 11.7ha of the 48ha reserve into 300 houses will be introduced to Parliament tomorrow. It doesn’t mention any wildlife whatsoever.

Here is my map of the area which shows where nationally vulnerable dotterel have nested in the past (this will now be houses).

I asked Auckland Council about the surveyors and was told they could tell me nothing. I have lots of signage in the area and yet no one has consulted with me or anyone who works with the birds.

When the houses, people dogs and cats come, where will the Tāmaki birds go? For those of you who know Tahuna Torea its a beautiful place but its not suitable habitat for wading birds. Dotterel have never bred there and with the mangroves, trees and people it is no longer the primary resting place of Torea (Oystercatcher). That job has been Point Englands for decades. Data here.

So with this last development will the Tāmaki Estuary lose the last of its shorebirds?

Evasive weeds

Drone

One of the hardest aspects of restoring and maintaining native habitat is weed control. Cliff faces are the most expensive often requiring carrying heavy loads to remote places and abseiling or a helicopter. Today I watched as DOC, Motuihe Trust and Yamaha trailed spraying pampas from an unmanned helicopter. The RMAX helicopters are piloted by remote control and used in a wide range of industrial and research applications overseas. The trial was a success and the team have plans to further improve the precision of the technology.

Fire on Browns Island

Just after the fire was put out on Browns Island I kayaked over to check on the shorebirds. I went for a short walk and was quite upset by the damage done to the reptiles.

I found so many burnt corpses. In places near the edge of the fire (where I think it was less hot) there was a native skink corpse (I checked the head scales) every meter or so. While sad it is nice to know so many lived on the island.

This rare moko skink survived despite having her tail badly burnt. While other surviving skinks can live of the fat reserves in their tails while their habitat recovers this one will have to work harder.

Although it was sad to see these golden bell frogs roasted alive, they are are not native. I was surprised to see them in multiple spots high up on the crater rim. Some seem to have survived under the rocks.

The rest of my photos here. Hopefully some good comes out of it.

UPDATE 30 DECEMBER 2016:
Six weeks later the grass has largely rejuvenated, however without the smothering grass, many seeds that lay dormant in the soil have germinated. Most of the new arrivals are invasive weeds, I saw wooly nightshade, apple of Sodom boneseed and moth plant. However the center of the crater is more interesting. From under the rocks bracken has emerged (how long could it have waited there?) and I think the reptiles will enjoy the extra cover.

Seacleaners

I had a great day out yesterday with Seacleaners (sponsored by Watercare in Auckland) and Wilkinson Environmental.

Plastic Pellets
Simon took a lot of photos of small plastic pellets (used in the manufacture of plastic products) that littered the foreshore. Unfortunately we could not clean these up.
Full boat
We loaded up most of the boat in less than an hour or two, we had to stack up the back of the boat to balance the load.
Bottle with black bottom section
I remember these bottles from my childhood, amazing how long it takes for plastic to breakdown.

Development

A large development in Glen Innes

I have always assumed when humans ‘develop’ land, some of it ends up in the ocean. I had a look at some of the Glen Innes development in the rain today to see what was going on.

It was good to see development companies trying but unfortunately all this mud ends up smothering marine life and poisoning the Hauraki Gulf. Not such a nice development.

Ambiance Impex

This is so gross – documented here for Auckland Councils Pollution Response Team.

The Ambiance Impex brands dumped into the stream are all branded Paradise.

impexWhen I first noticed the dumping in March and reported it to council the dumping was not so bad.

I wonder if the tires are from this dodgy looking bridge which is no longer there but is still visible in the council satellite imagery.

Even tho this site 120m from the Manukau (West coast of NZ) it flows through the Tamaki Estuary to the Hauraki Gulf (East coast of NZ).

UPDATE: 27 November.
Eight months later and the site is still sending plastic like these Paradise branded ‘cut green beans’ into the harbour. I am giving the council regular updates on the site but I don’t know how much (if any) is being cleaned up by Ambiance Impex or if its just getting washed into the ocean.

nov-27

UPDATE: 23 Feburary.
Ambiance Impex still show little regard for the environment sending further plastic into the stream.

UPDATE: January 2018.

Happy to report that after constant reporting the business has finally cleaned up their act.
