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.

Swimmable

I had a lot of fun illustrating this comic which explains what swimmable means.

It was fun to write myself into the comic in a socratic kinda way. I think I might do some more of these.

Pure New Zealand

James Cameron

I love James Cameron’s 2010 TED talk which has been used in the latest 100% Pure New Zealand campaign.

Like Cameron, I too grew up reading and drawing science fiction and exploring nature. This year my ‘journey of discovery’ took me deep into the Waitakeres for my own Avatar experience.

Bioluminescence Avatar

There, in the moonlight, I crouched in the middle of a small stream prodding and splashing away like a child. Like Jake Sully I was enchanted with tiny animals that (unlike glowworms who glow for hours) release a bright burst of bioluminescence. The limpets I was teasing are called Latia and they release bioluminescent slime as a defensive mechanism.

You won’t find these alien limpets anywhere else in the world and you also will no longer find them in most New Zealand streams. They need clean water, and we have filled our lakes and rivers with too much sediment for them to survive. Our waterways are far from 100% pure. Most of the rivers that are pristine are high in the South Island where it is too cold for Latia to survive.

Our government wants to treat our streams and rivers like drains. The legislation they have proposed sets extremely low standards for our waterways. I agree with the Parliamentary Commissioner for the Environment – sediment is one of the three big issues affecting our waterways. Yet our Government has not included sediment as an attribute in the National Policy Statement for Freshwater Management, and we can’t manage that which we do not measure.

In the 100% Pure ad James Cameron tells us that ‘curiosity is the most powerful thing we own’. My curiosity has changed the way I see the New Zealand environment. It has altered my enjoyment of the New Zealand wilderness. Where before I just saw bush, now see invasive plants. Having heard the morning chorus in our wildlife sanctuaries I am let down by our silent mainland forests.

So a few years ago I started a personal project about the positive stuff – the things that make New Zealand unique. MostNZ.com is a website showcasing what we can celebrate about New Zealand, how to experience those things and most importantly how to keep them. It’s a lot more honest than the 100% campaign but it’s still advertises New Zealand.

We can grow tourism and the economy by growing, protecting and restoring our wilderness. But to do it we need more, James Cameron; more curiosity, more imagination, more vision.

Let’s at least try for 50% pure. Let’s focus on the quality not the quantity of our exports. Let’s start doing restoration at an industrial scale and let’s really invest in our scientists who dream of a predator free New Zealand.

Like the narrative arc of James Cameron’s blockbusters we have tasks to master, battles to win and transformations to witness. The New Zealand story must have our unique environment at its heart.
James Cameron ends his Ted Talk with ‘‘No important endeavour that required innovation was done without risk.” – “Failure is an option, but fear is not.”

How to be wild and free

“No!” This is how we teach restraint, over time the child masters the rules and becomes a functioning member of society. But he finds pleasure in the quiet places where no one can yell “No” at him, places where the rules don’t apply, where he can be wild and free.

There is a huge psychological transformation that occurs when you’re outdoors and find that you are no longer alone. Every imaginable cultural judgement can be projected in just a single person. They are not just changing our behaviour they are changing how we think, making us self conscious.

Some people feel this more than others, but perhaps this is why humans bleat and stomp about environmental rules. Because when we are in the wild with all those wild things, we feel wild too. We feel free from all those rules and judgements, those “No”s. So we fight those that tell us “don’t go there”, “don’t kill that” or “leave that alone”. Because they are reducing our freedom, which is true. But unfortunately we live in a world of human expansion and decreasing environmental resilience, our choices now have a greater cost than those of previous generations. We are slowly learning we can longer afford to be wild, we have to share our freedoms, not just with this generation but the next one too.

The reason the human population has grown so fast is because we are so adaptable and culture (our behaviours and technology) has evolved and will continue to evolve much faster than our genes. Those that are following the rules, participating in restoration, conservation, trash removal, pest eradication, citizen science and moving from eating to recording wildlife are developling a new culture. This new culture is already growing fast and with it some of our wilderness is coming back, building resilience and expanding our freedoms. We are finding a new way to be wild and free.

Predators in our midst

A dead possum on a main road (near my house) in suburban Auckland.

When I first started trapping I was amazed by the quantity of Possums I caught. I worked multiple trapping lines in the city that were surrounded by houses, roads and waterways. Where were the possums coming from?

There were two articles about local rat ‘attacks’ Rat chews ear of sleeping 9-year-old & School warns students over rats after teen bitten by dying rodent recently. And they got me thinking again… where do they come from? Do the rats really come from the bush like the article claims or are the rats just as dense in suburbia? And what of the possums? Maybe it’s time we put some tracking tunnels and wax tags up in our backyards because if we really want a Predator Free NZ we are going to have to start at home.
