Come behind the scenes and into the jobs, the challenges, the highlights, and the personalities of the people who work at the Department of Conservation (DOC).

Today we profile Clayson Howell, a Science Advisor at DOC’s National Office.

My job is to…

Conduct research and provide advice on weed ecology and control, especially wilding conifers.

At the moment I’m working on understanding native succession under pine trees, better ways to kill wilding pines, and a GPS unit that records the location and volume of herbicide applied.

The scariest DOC moment I’ve had so far is…

Dragging a sea lion corpse through the surf on a short-leash at Enderby Island. The remaining males were fighting over it and the vet and I were trying to do an autopsy. We later figured out the cause of death was likely to be trauma after a shark attack.

I then witnessed the shark eat another sea lion in very shallow water. My short 0:35 sec clip (below) now has quarter of a million hits. My apologies for the voice-over, I’m no David Attenborough!

The DOC (or previous DOC) employee that inspires or enthuses me most is…

Not one person, but the people that make up the New Zealand Ecological Society. Collectively they are a wonderful bunch of clever, articulate and passionate New Zealanders who love telling stories about the amazing ecology of Aotearoa. This includes many current, former, and I hope future DOC staff.

On a personal note…

My stomping ground is…

Mckee Reserve in Ruby Bay, Nelson. A beautiful patch of remnant lowland bush that was literally over the back fence of my family home since I was six. It is the only significant piece of native bush between Nelson and the Abel Tasman. It contains several large matai trees and the biggest lancewood I’ve ever seen.

In my spare time I…

Cram in as many activities as possible. Lately this involves looking after my two kids on Fridays, as well as gardening, freediving, brewing beer and playing football. Before the kids came along I did a fair bit of rock climbing and tramping, which I hope to crank back up in the next few years.

My secret indulgence is…

Mycophagy. It sounds dodgy, but it isn’t. My not so secret indulgence is making and eating pizza in the oven I built.

My greatest sporting moment was when…

I climbed a rock called tombstone (Matukituki) in a plaster cast after I broke my ankle on the first day of a climbing trip. Or possibly when I steered the DOC dragon boat to victory in the social grand-final.

Deep and meaningful…

My favourite quote is…

“The fundamental cause of trouble in the world is that the stupid are cocksure while the intelligent are full of doubt.” – Bertrand Russell.

The best piece of advice I’ve ever been given is…

Always look a gift horse in the mouth.

In work and life I am motivated by…

People who form opinions and change their minds based on data, not pre-conceived ideas or faith.

My conservation advice to New Zealanders is…

Spend time outside, weed your garden, don’t be afraid to use herbicide carefully, support research to find ways of doing things better.

What story does your family always tell about you?

There are so many. This is probably my mum’s favourite…

As a small child I got lost at the Kaiteriteri Campground. It was the end of the summer and I was quite tanned. In between sobs I managed to get out that my name was Clay – son. The announcement over the camp loud speaker was that a small part-Chinese boy was lost. By the time my parents realised that I was missing from the roving band of kids, deduced that it was plausible that I could be mistaken for being part-Chinese, and got to the camp office – I was happily eating chips…

When I last blogged the 2012 Auckland Island expedition was getting ready for its final yellow-eyed penguin count on Enderby Island, and we were hoping for big things – or at the very least big numbers of penguins. Enderby Island is ‘the’ hotspot for yellow-eyed penguins in the Auckland islands – back in 1989, when he counted over 600 birds, Peter Moore calculated that it was home to a third of the island group’s penguins. We had a plan of action that would see us out of bed at 2.30 am and getting dropped ashore by inflatable dinghy by 3.30 am so that we could make our way – in the dark – to our counting sites, some of which were nearly an hour and half’s walk from the landing site in Sandy Bay. And as Enderby Island is also a hotspot for New Zealand sealions, we were all hoping that we wouldn’t encounter too many of those on the way!

By this stage of the expedition we had visited both Port Ross and Carnley Harbour and begun to get a good sense of the islands and their history as well as their wonderful wildlife and beautiful megaherbs, which are just starting to flower. There had been some exciting afternoon opportunities to visit some of the historic sites associated with the failed Hardwicke settlement and the many shipwrecks. And one memorable day, while most of the team took a much-enjoyed visit to the white-capped albatross colony at South-west Cape on Auckland Island, Jo Hiscock and I headed across to the south side of predator-free Adams Island to band some young Gibson’s wandering albatrosses. These birds have been the focus of a long-running study by Kath Walker and Graeme Elliott, who are concerned at the decline in fledging success each year and the disappearance of adult birds. It was a special privilege to get so close to the huge albatross chicks, which at nine months old are still patchily covered in soft white down, but which are already the size of their parents and well on the way to growing their adult feathers. I enjoyed the way each chick greeted our arrival with a percussion blast of bill clapping, and was very thankful that none of them chose to vomit oily fish over me (so my yellow PVC coat and trousers came home clean after all!). But it was very poignant to walk around the colony and find nest after empty nest which had already failed. Out of more than a hundred eggs laid in the study area earlier this year, only 40% or so still have a chick, and it is likely that more of these will die in the next few weeks before they are old enough to fly away.

The New Zealand sealions on Enderby Island, which have also been the focus of a long-term research project, have also seen a significant population decline over the last decade. For both species the causes of mortality include interactions with fisheries as well as possible changes in food supply related to changing sea temperatures and currents, while the sealion population has also been affected by several disease outbreaks. These stories highlight the fact that being isolated in the subantarctic is no guarantee of a safe future, which brings us back to the reason for our yellow-eyed penguin counting trip – to get a good estimate of their numbers now so that in future we’ll be able to tell if their population is increasing or decreasing.

Our Enderby Island yellow-eyed penguin count was certainly the highlight in terms of numbers of birds counted. Jo had the ‘landing of choice’ and clocked more than 70 birds heading out to sea. I was treated to a close-up and personal visit by some very curious penguins that couldn’t work out what this ‘thing’ on the edge of the cliff was, and Al was entertained by a penguin that got itself bluffed at the edge of an Auckland Island shag colony and took the only honourable option – a 3-metre leap into the waves below. But despite our one-day best we counted just two-thirds the number of yellow-eyed penguins that were counted on Enderby in 1989, and for the trip as a whole the figure was the same – 2012 penguin numbers were two-thirds those of 1989. These however are just the first crude results, and Jo still has to sit down for a more thorough analysis comparing search effort and many other variables.

In the meantime we can rest easily knowing that the 2012 Auckland Island Expedition was a success in every other way – we achieved all the penguin counts in all the sites that we wanted to survey, helped greatly by fine weather, smooth seas and a superb team of energetic and enthusiastic volunteers, who threw themselves whole-heartedly into their first subantarctic experience.

Last week I blogged about the penguin flotilla heading down to Campbell Island and the Auckland islands to carry out a survey of yellow-eyed penguins. This blog comes to you from aboard the yacht Evohe, at anchor off Enderby Island at the northern end of the Auckland islands. We’ve just completed our fifth yellow-eyed penguin beach count, and we still have one to carry out tomorrow. Team leader Jo Hiscock, along with Department of Conservation colleagues Dave Agnew and Megan Willans are currently in the inflatable dinghy with Mate Murray Watson, cruising the shore of Enderby Island to identify counting sites for tomorrow morning. We are expecting this to be our biggest count to date, as 23 years ago Peter Moore counted nearly 600 yellow-eyed penguins at sites around the island’s southern and eastern coasts.

We feel as if we’ve achieved 10 days work in five, as we have very early morning starts, and are cramming two days worth of activity into each day. Jo’s alarm goes off at 3.30 am, and everyone is up and ready to go ashore by 4.30 am, although on a couple of mornings the Evohe crew were up at about 2 am, moving us from our safe, calm anchoring spot to get us in position so that we only needed a short dinghy ride. As it is still pitch-dark we are navigating by spot-light to find the handy pieces of reflector tape that the scouting team have put in place to mark our landing spots, and then we each scramble ashore to our designated watching spot. We officially count from 5-9 am, but I have to say it is still pretty dim at 5.30 am, which makes it hard to identify if the penguins we see are adults or juveniles. By 5.45 am, however, it is all go.

We have been incredibly lucky with the weather, especially given the reputation of the Furious Fifties as being cold, wet and very windy. A smooth sailing down here has been followed by day after day of mostly calm overcast weather, with intermittent rain showers and even occasional outbreaks of blue sky and sunshine (although I have to admit there has just been a shout of ‘hail’ from the cockpit). Temperatures are certainly low, and by the end of four hours of sitting we are all chilled and wanting to move and stretch. But despite the discomfort everyone is having a great time. The six volunteers report they are loving every moment of the trip, and there is a friendly rivalry as to who sees the most penguins each morning. The record so far is Katie’s 18 penguins on Ewing Island, although she has also had a few days with zero penguins.

In many places rata forest comes down almost to the coast, on which rocky boulders alternate with small bluffs blotched with white lichens. The yellow-eyed penguins have to be accomplished boulder hoppers to get in and out of the water. Photo: Alison Ballance

So far we’ve carried out beach surveys (and we’re talking rocky shore platforms and bluffs rather than gentle sandy beaches) on Ewing and Rose islands, which are small islands close to Enderby Island, in Matheson Bay and North Harbour on the northern coast of the main Auckland Island, in Waterfall Inlet on the main island’s south-east coast, and on the north shore of Adams Island. We are trying to survey the same sites that Peter Moore surveyed in 1989 so we can compare figures, and so far our counts have been generally lower, apart from Ewing Island where we counted exactly the same number of birds. We’ve got our fingers crossed that our final morning tomorrow will see us rushed off our feet counting penguins on Enderby, as we’d love to get as many birds as Peter. I’ll let you know later in the week what our final grand penguin tally has been, and tell you about our sideline work on albatrosses. O and before I sign off I do have to let you know that we are now basking in sunshine and the sky is almost entirely blue – one thing that is certain down here is that the weather here is very fickle!

Sandy Bay on Enderby Island is a popular site for yellow-eyed penguins as well as New Zealand sealions – we’re hoping to count lots of penguins here tomorrow. Photo: Alison Ballance
