While in Kinabalu National Park, (Sabah, Malaysian Borneo) I’m not sure if our guide said “look up there” or I just noticed and photographed the pretty canopy outline then later heard about ‘canopy shyness’. I just know the narrow yet clear gaps between the tree crowns is attractive.
Canopy, or crown, shyness is, I now know after research, is a phenomenon in which some tree species make sure they do not touch each other: forming canopies with channel-like gaps. It’s most common among the same species.
This growth has been discussed in scientific literature since the 1920s and many hypotheses have been put forward as to crown shyness being an adaptive behaviour. Research suggests that it maybe stops the spread of leaf-eating insect larvae, and, or, also possible physical explanations such as light shading sensing by adjacent plants.
A Malaysian scholar, Francis S.P. Ng, studied (1977) the Malay camphor tree and suggested that the growing tips were sensitive to light levels so stopped growing when near other foliage due to the induced shade.
However, apparently, the most likely theory is that the trees simply do not want to hurt themselves in windy areas!
I wonder – I just know the gaps between the trees provided me with a couple of striking photos.
After breakfast at the delightful and historic Commercial Hotel I head out of Dargaville on SH12 to Matakohe – it’s 45ks to the award-winning Kauri Museum.
It was many years ago that I first visited this area and in the fifty years since the community started the museum it has grown in status and size. I suspect it’s unprecedented that a museum with no government funding, is run by a small rural community trust, and whose governance structure are all volunteers, becomes an acclaimed museum with international university studies centred there. The Kauri Museum ticks all those features.
Its latest award, in “The New Zealand Museum Awards” was last month (April 2013) where they won the award for ‘an outstanding innovative project that contributes to the best practice in the Museum Sector in New Zealand’. The project was for Achieving CarboNZero Certification – Now there is no doubt – it’s a world-leading, sustainable, museum operation.
The goal of becoming the world’s first carboNZero certified museum was driven by a desire for integrity and their chief executive Bet Nelley said,
“It’s our answer to long distance travellers who find the story of the demise of the kauri tree sad. And, as environmental responsibility is one of our core values, it made sense for us to get a recognised measure of our carbon emissions that we could work to reduce and offset.”
The museum also provides a base for a scientific research project into dendrochronology – a huge word that means tree-ring dating based on the analysis of patterns of tree rings!
Dendrochronologist Dr Jonathan Palmer (supported by Exeter University (UK) and University of Auckland) is developing an archive of ancient kauri samples to help unlock secrets from the past, and museum displays to chronicle scientific research into kauri.
Over a coffee with the three scientists (Jonathon Palmer, Gerd Helle, Alan Hogg) they tell me their research with the rings, pollen and carbon dating is proving really useful as the age of the trees give a longer time period to look at the effects of climate change especially in the southern hemisphere and which has implications for the northern hemisphere research too.
They were at The Kauri Museum to discuss how best to glean the most informative climate data from buried kauri tree-rings. Dr Alan Hogg from Waikato University was helping to give a date of when the trees were growing by radiocarbon dating. The museum’s resident scientist, Dr Jonathan Palmer is looking at the ring-widths to consider past climate patterns (such as El Nino / La Nina frequency) while Dr Gerd Helle (Potsdam, Germany) is specialised at “using isotopes of oxygen and carbon to determine past temperature and moisture levels.”
The three are intending to work together on a particular time period of abrupt climate change so that the most climate information can be obtained from these amazing native New Zealand trees.
This social history museum tells the fascinating story of the kauri and local pioneering days via the use of kauri timber and kauri gum, starting when the settlers came to the area in 1862 – this museum was born 100 years later in 1962.
With exceptional displays and dedicated galleries this is a must do for your Northland bucket-list. These including a magnificent collection of antique kauri furniture, restored machinery (including NZ’s earliest tractor) a turning Steam Sawmill and fabulously, the world’s largest collection of kauri gum.
I wasn’t sure what the difference between amber and kauri gum was – but can now describe it for you: amber is older, so harder, than kauri gum with amber 25 – 200+ million years old, while the gum is a baby at only 43 million years old! I also learnt that kauri timber ranges from gold and golden brown through to green, yellow, browns and blacks. Kauri is one of New Zealand’s treasures – the other is pounamu – greenstone (jade).
Most Kauri were felled in the 1800 – 1900’s for timber for houses and today owners of those old homes treasure their polished kauri floors while tourists buy souvenirs or art works made from swamp kauri or recycled wood from old buildings. Unfortunately there are only about 4% of kauri forest left and they are at risk of kauri dieback disease. The Kauri Coast is the only place to see New Zealand’s ancient trees and is a must-do while traveling the Twin Coast Highway.
My souvenir from this exceptional museum is a beautiful gift – a piece of kauri gum which lives in on top of my very old walnut writing desk. Very special and, thank you Betty.
I recommend you allow at least 1 ½ hours to browse around this fascinating place – see what Trip Advisor members say about the museum. (A hint – it’s ‘excellent’)
My Northland road-trip was in a NZ Rent A Car vehicle and I can endorse both, and this unique museum – I shall return!
The Hokianga is not just blue skies, massive sand dunes and ancient trees – it’s also the cradle of not only Ngapuhi, but also of the European settlers in the early 1800s.
I have done too much in the last 24, or so, hours for a little blog, but there are plenty of stories to come out of this area from my pen and camera. Lonely Planet raved about Footprints Waipoua (@hokimustdos) and so will I! I took the evening guided walk – with 6 others from Canada, USA, and the Bahamas’ – and we all voted it fabulous. Our local Maori guide, Koro, really did guide us through the forest and introduced us to the biggest, and oldest of the kauri trees in the Waipoua Forest, and more. I don’t want to spoil the story now – book mark this blog and come back for more. (Or watch the airline magazines for this one!)
Another one that’s worthy of a bigger audience than this blog – although my numbers of readers have gone up while I’ve been travelling Northland, so welcome to you who are just discovering NZ and my travels – next overseas trip will be Turkey hopefully and, absolutely, Borneo later this year. But back to the story that deserves a post and printed article is Sandtrails Hokianga which i went on this am.
See the photo of the sun just hitting the sand dunes (taken from my room at the Copthorne Hotel &Resort Hokianga) well that was just the start of an adventure, great scenery, and an introduction to Andrew Kendall’s tribal history – including the arrival of Kupe. Like our guide last night, he is a really nice guy: what even better, this tour is an exclusive, limited to three people! I suggest you book in advance if you can.
