The Last Tree in Papanui Bush. And that last palm tree on Easter Island

“What did the kiwi bloke say while cutting down the last tree in Papanui Bush?” Here, I’m just re-phrasing of the question Jared Diamond wrote in his 2005 book ‘Collapse’. The original question Diamond posed was: “What did the Easter Islander say while cutting down the last palm tree?” Diamond was trying to make a… Continue reading The Last Tree in Papanui Bush.

The Invincible Children of Kharkiv – Musicians in the ‘City without Windows’

The band Teenager Stars, in Kharkiv. Ten year-old Daniil is singing, to his left, Lisa is on the drums, and to his right, Iryna is on the organ. The organiser, Yuri Mischenko, is in the back, playing the drums.

Kharkiv, in the far north-east of Ukraine, has been described as ‘a city without windows’ (Mayor Ihor Terekhov in a Twitter post of June 27, 2025).  The city’s location, just a twenty minute drive from the front line, had seen it occupied early in the Russian invasion, then liberated by the Ukrainians, but it remains… Continue reading The Invincible Children of Kharkiv – Musicians in the ‘City without Windows’

The Hollow Tree Stumps at Curio Bay

A hollow tree stump at the Jurassic fossil forest of Curio Bay, New Zealand. The inside of the stump (the wood is yellow, and has come black, 'coally' material inside) has been filled with sandy material (grey). Could this be an in-filled fire-scar?

Geography and the Bronze Age Battle at Tollense, Germany

One of the beauties of modern archaeological technique is the ability to analyse ancient battle, or massacre sites, in a forensic way. This has happened at the famous Teutoberg Forest site in northern Germany, and is happening in the also famous ‘Tollense’, site in north-western Germany. It’s become known as the earliest battle site in… Continue reading Geography and the Bronze Age Battle at Tollense, Germany

Was there a Forest before Central Otago’s Kowhai Forest?

When humans arrived in New Zealand, a bit over 700 years ago (Wilmshurst et al., 2008; Jacomb et al., 2014), it seems some of the driest parts of the country, in Central Otago, were under low forest, dominated by kowhai (Pole, 2022). Specifically, this was on the lower slopes of the gorges and slopes of… Continue reading Was there a Forest before Central Otago’s Kowhai Forest?

Dunedin’s Saddlebacks/Tieke and Yellowheads/Mopua

Amateur field observations of species can be priceless. A local Dunedin man (Peter Thomson, 1823-1879), using the pen-name ‘Pakeha’, wrote several accounts of his ‘rambles’ around the area between 1864 and 1879. They appeared in Dunedin’s newspapers the Otago Witness and the Otago Daily Times (see articles by the historian Paul Star, 1998, and by… Continue reading Dunedin’s Saddlebacks/Tieke and Yellowheads/Mopua

Green Island Bush – Divide and Conquer

Green Island Bush is a prime example of a large patch of New Zealand indigenous forest that was essentially annihilated in the late nineteenth century. It lay between today’s Green Island suburb, on Dunedin’s Southern Motorway, and the coast. Today the area is mainly farmland. Its original extent is shown partly on Charles Kettle’s 1849… Continue reading Green Island Bush – Divide and Conquer

The Lost Ecosystem of the Leith Swamp Forest, Dunedin

A portion of 'Kettle's 1847 map, 'Otago Land District SO 6’, showing the 'Leith Delta'. The green shading is interpreted as mostly 'bush/forest'.

One part of Dunedin is different from the rest…. The Dunedin area is an old volcano. It’s formed mostly from the molten, or semi-molten material that forced its way up from below, or some of the older marine strata that this material pushed its way through. In the few million years since the Dunedin volcano… Continue reading The Lost Ecosystem of the Leith Swamp Forest, Dunedin

Ten Years Trapped in Mongolia – Time to get Mo Munshi home to Australia

In 2007, I started work in Mongolia as a geologist with the company, Gobi Coal and Energy Limited. The Chairman was Mohammed ‘Mo’ Munshi – a citizen of Australia and the United Kingdom and Northern Ireland, and with a young family in Beijing. The next few years were an amazing time, as I got an… Continue reading Ten Years Trapped in Mongolia – Time to get Mo Munshi home to Australia

The Ancient Footpath from Otepoti-Dunedin to Moeraki

A portion of the ancient Maori footpath out of Otepoti-Dunedin shown (the dotted line to the left) on Thomson’s 1857 map. I have cropped this from: R10302722. ‘Reconnaissance Survey of Otago Province - North Eastern Districts’ - John Turnbull Thomson, Chief Surveyor (1857).

How old is the oldest cultural feature on Aotearoa-New Zealand? Imagine being around when the only way to get anywhere was to walk or take a waka (canoe). That was New Zealand in pre-European times – there were no pack animals. When settlers arrived in what was to become Dunedin, in 1848, there was no… Continue reading The Ancient Footpath from Otepoti-Dunedin to Moeraki
