Perhaps the most surprising thing about Nothofagus leaf fossils in New Zealand is – not finding them. Nothofagus is another name for the southern beech trees that form forests in New Zealand, as well as Australia, Patagonia, New Caledonia and New Guinea. As a group, the beeches are certainly an old element in New Zealand, with at least… Continue reading Miocene Nothofagus in New Zealand’s Manuherikia Group

Blue Lake, St Bathans – the most biodiverse Miocene fossil plant locality
The biodiversity of Blue Lake, at St Bathans, New Zealand, is precisely zero. It is an artificial lake partly filling a hole blasted out in the search for gold in the 19th century. The hole is directly in front of one of St Bathan’s and New Zealand’s gems – the Vulcan Hotel. If you ran out… Continue reading Blue Lake, St Bathans – the most biodiverse Miocene fossil plant locality
Giant Pea Pod fossils in New Zealand’s Miocene
Pea pod fossils in New Zealand were first found by Aline Holden, a pioneer of New Zealand plant fossil research. She found the first ones at Bannockburn in 1981, while working on her PhD, and then found more in the Nevis Valley. In 1987, my PhD professor, J.D. Campbell and his wife, Anne, dropped in… Continue reading Giant Pea Pod fossils in New Zealand’s Miocene
The Fossil Palm Swamps of Central Otago, New Zealand
One of the endearing memories I have during my PhD was working on the banks above the Kawarau River near Cromwell (Central Otago, New Zealand), in the middle of the winter. I was belting my way with a pick into a sequence of mud that was frozen solid. This was probably a good thing, as… Continue reading The Fossil Palm Swamps of Central Otago, New Zealand

Australia’s Fatal Fire-Flume
The first time I came to Brisbane in the hot part of the year – I couldn’t believe how anyone could survive there. The nights were oppressively, putridly hot, and full of bitey-insects. Then I ended up living there and suffered for years. I would cocoon myself in a mosquito net, and poke a fan… Continue reading Australia’s Fatal Fire-Flume
Four Degrees of Climate Change in New Zealand – should we care?
New Zealand might be a relatively lucky position as regards global warming. We mostly have a moderate, ‘maritime’ climate. Not too hot, too dry, and except for the dirty dribbles of ice we make so much of, no ice-sheets to melt. We’re not like Australia, where the ‘normal’ run of extreme heat, drought, and fire is… Continue reading Four Degrees of Climate Change in New Zealand – should we care?
Flooded Forests: sea-level rise in the Haast, West Coast, New Zealand
I own a little patch of bush in the Haast, on the wet, West Coast of New Zealand. It was selectively logged a few decades ago, which meant that the large podocarp trees were removed. It then became the edge of what was left of the forest, and farmland. I bought it with the intention… Continue reading Flooded Forests: sea-level rise in the Haast, West Coast, New Zealand
Matai- vanquished giant of New Zealand’s dry forests?
I’ve long found New Zealand’s black pine, the matai (Prumnopitys taxifolia) to be a special tree. From a dishevelled juvenile, It can grow into one of our tallest and oldest plants. Its foliage, unlike the delicate feathers of its smaller relative the miro, has a more scruffy appearance. It is by no means rare, but… Continue reading Matai- vanquished giant of New Zealand’s dry forests?
Thin Ice? Climate change in Alexandra and skating on the Manorburn Dam
Growing up in Alexandra (Central Otago, New Zealand) in the early 1970s it was the family thing to go ice skating on the Manorburn Dam, a short drive from town. It was a very social occasion, with heaps of the rest of Alexandra there too, daytime and after dark too. You could either go on… Continue reading Thin Ice?
