Raoul Island is one of the Kermadec Islands, about 1,000km north-east of New Zealand in the South Pacific Ocean. DOC has a small team of rangers and volunteers who live on the island in relative solitude. Their main focus is controlling weeds on the island, maintaining infrastructure such as buildings, roads and tracks, and carrying out work for Met Service and GNS.
Since the island is so remote, we get these diary entries from the team and post them up on their behalf. Today’s diary is by volunteer, Nicki Atkinson.

Time is flying by, I’m almost half way into my 5 month stint on Raoul Island as a volunteer and already I don’t want to leave!

I am getting used to island life now and haven’t experienced a second of boredom yet. These first few months have been fairly action packed with a visit from 14 German ham radio operators in November, an air drop as well as Xmas and New Year celebrations – all of which successfully distracted the team from, well, ourselves mostly!

Hamming it up

The ham radio guys (and one geek lady!) were an interesting pack. I didn’t know a lot about ham radio before they came – and actually I still don’t! They spent three weeks solid tapping out their call signs in tents that were pitched among a web of aerials. They worked as a team, on a rotation of twelve hour shifts, to make contact with as many other ham radio operators around the world as they could (apparently they did quite well with 140,000 odd contacts made).

We had a number of social gatherings with them and a few of our team took them up to the highest point of the island, Moumoukai, and along the beach near our accommodation. I did not get to know them particularly well however, and the day they were packing up, Sian and I walked passed their camp and saw one guy that both of us had never met before – a strange concept on an island that only had 25 people on it!

Into the blue

Jess, Toby and I managed to go for a dive while the Braveheart was here (the boat that brought the radio hams up) as they had a compressor and gear on board.

Unfortunately the visibility wasn’t great and an absence of any logical sense of direction (or a compass) hampered our efforts to navigate from the boat to the edge of the Meyer islands. By the time we got to the best part we were getting low on air.

Nevertheless we found ourselves in an undersea world with an intricate abundance of life only a semi-tropical marine reserve could produce – sharks, thick schools of docile kahawai and king fish, fluorescent wrasse, giant groupers and many more creatures all dancing in time with the surge of waves. Magic!

The marine environment here is just awesome! It’s rugged and dynamic and overflowing with life; we’ve been swimming with dolphins, seen huge sharks, turtles and whales, and been kept awake at night with cries from sea birds and crashing waves.

The sea temperature is up around the 25oC mark and whipping down to the beach for a swim, at least twice a day, has become part of the normal routine.

To the other side

Not long after the radio hams left, the weeding crusade took us west over to Denham Bay for a week. The bay stretches out 3km or so with a black sandy beach adjoining a thin strip of flat, pohutukawa-laden forest that is jutted up against steep cliffs and the edge of a caldera.

With a west facing outlook, we spent every evening on the beach immersed in golden sunsets, magnifying the natural beauty of the bay.

Denham Bay is an area of the island that is particularly steeped in history; remnant fruit trees and artefacts from the Bell family era that began in the late 1880’s, graves of various sailors succumbing to sickness and shipwrecks, and the tales of slave ships dumping plague-ridden slaves overboard in the bay as a means of sorting the weak from the strong.

These stories of the past all give the bay an eerie tinge of harsh unhealed realities – a feeling that  is now often masked by the development of our relatively luxuriant lifestyles (at least it is in NZ). It is these, remote, raw and untouched aspects of the island that I have come to love the most.

Festivities

Come the end of December, Christmas and New Year festivities were in full swing on Raoul. We kicked off on Christmas Eve with a golf tournament generously organised by our mechanic, Tim.

There were a number of stringently enforced rules – no using names, attire had to be inappropriate, losing your ball resulted in the consumption of a beverage blindly chosen from a substandard selection of beer – as did taking a swing and missing the ball, cheating, and arguing with the organising committee (aka Tim).

The nine hole course was challenging with the second tee-off at the top of a cliff with the hole on the beach below while the fifth required an accurate and highly elevated shot over top of the workshop. Most surprisingly my ball landed closest to the pin on more than one occasion and I began to set my sights on the prestigious Green Jacket.

A couple of slips ups – missing the ball – of course due to the increasing  unbalanced set of golf clubs – resulted in my high sights being dashed down to second place which I shared with Maree . Toby took away the Green Jacket by four strokes and is now the new holder of the prestigious ‘Raoul Island Golf Tournament’ trophy

I’ve enjoyed the first half of my stint on Raoul so much – I can’t wait to see what more I can get out of it in the next half!

Changeover week

Not many people get the opportunity to visit let alone live on Rangitahua (Raoul Island), the little subtropical treasure in the pacific. I have been lucky enough to return to this island which is again becoming home to a new team.

After 3 months training on the mainland we finally saw our first glimpse of Raoul Island from the vessel Braveheart at 5am on 25 October 2010. The drizzling weather did not dampen the mood after being welcomed around Hutchies Bluff by a pod of dolphins and a couple of whales breaching in the near distance.

We had a busy changeover week with over 20 people on the island, including staff from GNS, Metservice, and DOC. During this week the previous team filled our brains with masses of valuable knowledge on how to run the island! We also managed to find time for countless volleyball matches, a tug of war competition and a memorable dress up party to send off the old team.

The week flew by, and the old team were given a typical Raoul Island salute send off. Then there were 8! It’s a strange feeling watching the boat leave, knowing the island is now in our hands.

On the airwaves

Two weeks later we had Braveheart return to the island bringing with them 14 ham radio enthusiasts from Germany, Poland and Greece.  So again the island was alive with people!

The “hammies” set up aerials all over the airstrip and spent 2 weeks on their radios attempting to contact as many people as possible all over the world. They had a successful trip, and even managed to find some time for a few guided walks and a great party at the end of their stay.

Down to work

Since the previous teams departure we have been busy getting our heads around all the tasks necessary to smoothly run a 3000 hectare island.  The weed programme is our main priority and is one of the key reasons we are here. We have all been introduced to the joys of weeding. We have been battling steep ground, scrambling through fern and finding weeds a plenty!  Scratched arms, legs and bruises are a good sign of a hard day’s work on Raoul Island.

We also carry out contracts for Metservice and GNS.  A hydrogen filled weather balloon is released each day and water samples are taken from the crater lakes monthly.

Downtime

When we are not working we keep ourselves busy with essential day to day jobs such as maintaining the vege gardens, mowing lawns, cooking and baking. We have had a few experimental successes in the kitchen making chilli sauces, kawakawa chutneys, orange wine and flavoured beers with our local produce.

There is also plenty of time for exploring the island, snorkelling, swimming, surfing and of course the occasional dress up party. The next few weeks on the island will be spent weeding, enjoying the festive season and making the most of our time on the remote island paradise we now call home!

Kermadec Islands

Raoul Island volunteer programme

Hi Everyone,

I wanted to keep you informed of the events unfolding on Ulva Island at the moment.

Twelve rats have been caught on Ulva Island in the last two weeks.

After four rats were caught on Ulva Island in June/July 2010, DOC staff were hopeful that the incursion to this rat free island had been contained. However, in October a keen eyed member of the public passed on a photo of animal prints he took in a muddy creek on the island. DOC experts confirmed that these were made by a rat.

Ulva Island has a network of traps and poison bait stations that are run year round to kill any rats that may get to the island and extra traps were added to this and the frequency of checks increased. Tracking tunnels were also used to try and detect any rats on other parts of the island.

Between August and December, no further rats were caught or detected. This all changed after Christmas day – a total of 12 rats have since been trapped. Of greatest concern is that one of the rats was a juvenile which indicates there is now a breeding population on the island.

DOC staff have been diverted from other work to check the traps and tunnels on a weekly basis. A DOC team of experts will meet shortly to plan a course of action to remove rats from Ulva Island as rapidly as possible.

Since rats were first removed from Ulva Island, on average one rat a year manages to get to Ulva Island either by swimming or hitch-hiking with boats. To date, we have managed to catch these rats as they arrive, preventing them from breeding. This is the first time a rat has evaded all of our traps, established and bred.

Removing and then keeping rats off the island is a difficult task and there is always a chance that we may not succeed. DOC has an excellent record in this field but as always we will need the help and support of the public to achieve this.

I’ll aim to send regular updates out over the next few weeks.

26 January update

Unfortunately, the picture isn’t getting any better on Ulva Island. Further trap checks have now brought the total number of rats caught to twenty. On top of this, we have been running ten lines of tracking tunnels (baited with peanut butter and have an ink card in them that records footprints). Five of these lines have recorded rat footprints (34% of tunnels). This confirms that the rats are widespread over Ulva Island.

We are meeting tomorrow to plan the best way to eradicate these rats. Luckily, within New Zealand, we are able to draw on some of the best rat eradication expertise in the world. I will let you know what the recommendation is as soon as I practically can.

The rats that we have caught aren’t going to waste. Tissue samples are being sent away for DNA analysis to confirm that they are all related (and hence only one invasion event) and to work out where they came from. This will be achieved by comparing the DNA of rats on Ulva with sample rats from different locations around Paterson Inlet and Bluff. The rest of the rat will be sent to the vet school at Massey University who will be able to provide information on sex, age and if they have bred or not.

We will continue trapping and running the monitoring tunnels to keep track of the dispersal and population growth of these rats. Hopefully, this will also keep numbers suppressed. The set-up that we have on Ulva will not achieve eradication of the rat population that has established. Something further will be required.

We have had many offers of help and support. These are really appreciated and are being built into the planning of how we might achieve eradication.

Regards
Brent

8 February update

The last few weeks that we have been doing intensive trapping have revealed quite a depressing picture. Over 40 rats have now been caught and most of the tracking lines across the island are tracking rats. In short, the population of rats is widespread and rapidly growing.  The trap set up that is presently on Ulva Island was designed to catch and dispatch individual rats as they invaded the island. The trap set up is no longer going to prevent this rat population from growing rapidly on Ulva Island. They are expected to reach maximum population density (regardless of trapping effort) within the next 12 months, possibly as soon as five months. The impacts on the island at this point will be severe. We plan on continuing to check the traps and tracking tunnels to keep track of rat population growth, but apart from this, the traps are past the point of achieving anything useful.

The best focus of activity now is on actions around eradication options. Last weeks expert meeting (involving members of the Islands Eradication Advisory Group) came out with only two options that had any hope of achieving eradication. Both of these involve getting widespread rat bait onto Ulva Island either by an intensive bait station network or by helicopter spreading. We are currently working through the financial costs and the pros, cons and risks of both options and this is what we will be discussing at the series of meetings on Stewart Island during the week of the 14th Feb. Once we, as a community, agree to the best path forward then we can get stuck into achieving it as rapidly as possible.

So, thanks heaps for your support and I am very sorry to have to send this message. It is really hard to believe that it was only one month ago that the first of these rats started turning up in traps.

The grand opening of the new derrick shed.

Ash & Nichy opening the much improved derrick shed

When we are not out and about in the hills weeding there is more than enough work to keep us out of trouble keeping the station up and running.

One to two days a week are dedicated maintenance days for tasks such as painting and gardening and road/track work but we have also had a number of small (and a few large) projects on the go during the last six months.

Derrick refit

Cyclone Thomas hit Raoul back in March and was by all accounts pretty spectacular and the derrick shed received a pounding.

Ash had been itching to get to work on it and with the help of his trusty assistant Nichy they tore all but one wall down and set to work re-building it.

After some hard labor we had our weekly Friday night drinks down at Fishing Rock for the grand opening.  We were advised to bring sunnies (needed to protect our eyes from the bright white paint).

After a tour of the shed with highlights including the new roof with a perspex panel to let more light in and the derrick operators seat it was time to cut the pink ribbon marking the new derrick winch housing open!

The upgraded Mahoe hut.

Hut facelifts

Mahoe and Hutchies huts were voted to be the most in need of attention.

First the areas around the huts were cleared right back with quite a few trees coming down (there were a few tense moments but both huts are still standing (and all the hebes are accounted for), allowing more light in and a bit more room for air to circulate.

Stu and Heather then moved in and set to work with their paint brushes, Mahoe taking a little longer than expected with the weather not cooperating resulting in Stu and Heather returning to base a little skinier and Stu very glad to be getting something more than “just potatoes” for his dinner!  The end result: two very flash looking huts.

Tracks

A scrub and chainsaw have been making their way around the island starting from the Moumouaki track, with Ian and Ash doing  the chain saw work and everybody helping with the scrub cutting.

The tracks are looking super! We now have a Hutchies highway and a Mahoe motorway. Now we have started though stopping is going to be very difficult – the small tracks that haven’t been done, like the ring buster, look like a jungle in comparison!

Emergency fire reservoir

When we had a few days of rain on the cards our leader Ian thought it was about time we gave our emergency fire reservoir a good clean out. It is 100,000 litres and is filled from the hostel roof stormwater.

It took nearly three hours and two pumps to empty the majority of the water. We then spent the rest of the day cleaning the base and sides and getting the last dregs out with buckets, then mops, then towels! (I think it could do with a plug at the bottom!)

It was shining once we had finished! Summer is definitely here and a few days later it was full enough to be put to good use!
