New Caledonia fern collecting

I’m just back from three weeks collecting ferns in New Caledonia.

For a place so close to New Zealand (shorter flight time than to Australia), I knew very little about New Caledonia. I expect that is true for many New Zealanders, and it presumably reflects our very different cultures, not least being the language difference (French predominates in New Caledonia, and English* in New Zealand).

New Caledonia is not an independent country but a special collectivity of France. Nouméa, its largest city, is like a piece of France transplanted to the tropical Pacific. The original Melanesian character is perhaps most strongly retained in the (north-)east.

Funded principally by a grant from the USA’s National Science Foundation, our collecting expedition was led by Matt von Konrat (Field Museum), Blanka Shaw (Duke University), and Louis Thouvenot, who was our guide and translator (none of the others in the expedition had been to New Caledonia before or spoke French, although Juan’s Spanish was useful on many occasions). The main goal was to collect Frullania liverworts, but we variously collected mosses, liverworts, and lichens – these are all small plants that are often neglected. I was invited along to collect ferns.

New Caledonia is home to about 270 ferns and lycophytes. That’s more than New Zealand, despite a land area less than 10%. About 35% of New Caledonia’s ferns and lycophytes are endemic (i.e., only found there), which is very high for a tropical Pacific island. However, the last comprehensive account is from 1969, and it is clear that much revision is needed. A reflection of this is that there are (at least) two species of new tree fern needing scientific description. During the three week expedition, I made 232 collections, of at least 160 different species. These include new species, new records for New Caledonia, and rediscoveries (species not recorded for a long time).

The Endemia website includes photos of many of New Caledonia’s ferns, and is an excellent photographic resource about New Caledonia’s biodiversity

In coming days I’ll post about some of the plants I saw, particularly, of course, the ferns.

The expedition couldn’t have been the success it was without the assistance of many, especially Louis Thouvenot, as well as the Nouméa herbarium, the government land managers, the Kanak land owners and guides, and our contacts at Dayu Biik, Conservation International, and Société Calédonienne d’Ornithologie.

* I can note that the so-called ‘English’ speech of the two (monolingual) New Zealanders was constantly belittled by the other members (all multilingual) of the expedition, none of whom spoke English as a first language. Matt and I weren’t sure what to make of this.

Fish research team en route for the cold waters of the Sub Antarctic Islands

It’s only about three years I have been living in New Zealand and there is still plenty to learn about the country. But one thing I already know for sure, it’s that February is the best month in the year to enjoy good sun, low winds and warm weather. It might actually be the only one! So I am starting to think that I might be a little bit insane to plan a survey down the Sub Antarctic islands, right in the middle of February. Of course there is a very good reason to do this, but it comes at the cost of abandoning my dreams of diving warm waters this summer.

Map showing the sampling locations already achieved (green) and the two locations still to be sampled (red).

February is supposedly the best month of the year and this should also apply to the Auckland Islands where we will be studying the taxonomy, ecology and behaviour of the fish fauna in cold and deep waters. With the use of our video systems, we are going to film the never filmed before: the deep-sea fauna of those very wild and remote islands.

The Auckland Islands are located at 51°S, about 500 km south of Invercargill and are basically lost in the middle of the Ocean. The group of islands is 43 km long by 24 km wide. The first stretch of land on the West is the tip of South America, some 8000 km away. The first land on the East is actually also South America, and is not closer. This means that winds, rarely dropping under 60 km/h, and sea state can be remarkably unfriendly in the Auckland Islands, with no protection from land for thousands of kilometres. Now you start understanding why I am ready to give up on some mainland New Zealand warmth, in the hope of having acceptable conditions to deploy our video systems.

During this survey, we will also stop by around the Otago Peninsula to do similar work. We will sample the deep canyons up to 1200 m, learning more about fish diversity and behaviour in the area.

In one day, our boat the MV Tranquil Image will be in Wellington and we will be departing.

Speak to you soon,

Campbell Island Bicentennial Expedition

Right now, on New Zealand’s southernmost island group, a team of 11 researchers and their support crew are wandering around the cold, windswept Campbell Island, studying the island’s rich ecology and history, and its recovery from decades of grazing and the world’s largest island rat eradication.

And you can follow what they are doing day by day on the Campbell Island Bicentennial Expedition website and Facebook page. There are almost daily blogs from the researchers, and growing albums of photos and videos showcasing what a remarkable and wild part of the planet Campbell Island is.

Located in the sub-Antarctic ‘Furious Fifties’, Campbell Island was discovered 200 years ago in 1810 by Captain Frederick Hasselburg of the sealing brig Perseverance. At least that’s the commonly told story. But was the island discovered a lot earlier, by Polynesian voyagers? No one really knows when the remote outlying islands of New Zealand were first occupied by people, and archaeological work around the Island’s coast, in rock shelters suitable for human habitation may reveal the answer, and shed light on the limits of Polynesian voyaging.

This is just one of several exciting research projects being conducted on this Expedition.

Campbell Island is well-known for its ‘goblin forests’ and megaherbs; sea lions, albatross and endemic birds like the Campbell Island teal, but comparatively little is known about the freshwater life and invertebrate fauna there, and especially how these creatures have responded to the extermination of livestock on the island, and the eradication of rats in 2001. The Expedition marks 10 years since the last Brown or Norway Rat was killed, and a major research focus is to evaluate how the vegetation and invertebrate fauna are recovering.

The dramatic and devastating impact that rats have had on New Zealand’s fauna is featured in Te Papa’s exhibition Blood Earth Fire – Whangai Whenua Ahi Kā. Depending on what material is collected by the Expedition team members, some of these critters, along with photos and videos taken by the team might be displayed in Te Papa from about December 2012, when the major research outcomes from the Expedition should be known. The display would likely be adjacent to Blood Earth Fire, updating the fantastic island conservation story there, a conservation approach where New Zealand is a world leader.

In the meantime though – check out the Expedition online sites and find out what it is like to live and work in one of the world’s truly isolated places, and perhaps witness discoveries as they happen! The expedition will span nine weeks from 6 Dec 2010 to 12 Feb 2011. So while we are out enjoying the sun and warm weather, the Expedition team will be wrapped up in thermals, or shivering in some freezing stream, or getting chased by sea lions, or pecked by penguins, or… lucky buggers!
