The Great ACT-NSW-NZ Trip, 2023-2024 - Taranaki Maunga
A 2,518 metres (8,261 ft) tall stratovolcano, ideally positioned to catch every change in the weather coming off the Tasman. As a result it gets up to 11 meters of rain a year, and the winds between the peak and the remains of its predecessor can exceed 130kph.

Naturally, of great importance to the local iwi, and it certainly made an impression of the Europeans too - although a lot of early paintings exaggerate the height.

watercolour by Charles Heaphy, some time between 1839 and 1849.
They named it Mt Egmont, although happily the original name is back to being the official one.
The volcano erupts, on average, every 90 years, with major eruptions every 500. Of considerably more concern are the repeated catastrophic cone collapses that turn most of the volcano into gigantic landslides sweeping fridge-sized boulders and smaller debris dozens of kilometers away from the volcano, and well past the current coastline.
Anyway, while we wait for it to go bang again, visitors can enjoy the fascinating change in vegetation as you go up the mountain. As you get higher and higher, the coastal vegetation is replaced by the goblin forests, contorted mossy woods dominated by Kamahi (Weinmannia racemosa), that developed after eruptions destroyed the preexisting podocarp and Nothofagus forest, and as you go higher the trees are replaced by tussock grasses and later alpine plants.

There are still kiwi in the national park, which is one reason dogs are strictly banned. The introduced stoats continue to be a problem - we saw one on one of the tracks.

There was also this building, a corrugated iron structure noteworthy for being the oldest such building left anywhere in the world. It was originally a fort, and still has gun slits. The windows are new.
Most of the species I saw around the visitors center are were new to me - I could have spent a week just phtographing the incredible lichens in the goblin forest. Here's some that weren't new.

And a few lichens I don't have an ID on.

Sampinur Rope (Dacrydium elatum), my first record of wild Dacrydium species. Glad to see the seedlings are everywhere on the forest floor, and the young trees are surprisingly smooth and soft.

Unveiling the Magic of Podocarpus in The Perfect Hedge
The screen of every garden or park justifying its beauty is done by yellow wood plants or Podocarpus species. These are the most widely spread family of Podocarpaceae. They belongs sot the genus Conifers. These are evergreen shrubs or small trees. They are widely used as ornamental plants for parks, gardens, and roadsides.
The name Podocarpus is derived from a Greek language. ‘Podus’ means foot and ‘karpous’ means fruit. The family of Podocarpus, that is Podocarpaceae consists of 97 to 107 species. They are commonly called ‘yellow-wood’ or ‘pine’.
Podocarpus Dispersion
Podocarpus are the most widely distributed Podocarp family. The plant is native to Africa, Asia, Australia, Central and Southern America, and many Pacific Islands. In ancient times it was endemic to Africa, South America, India, and New Zealand for some time about 105 to 45 million years. It is also known as Antarctic flora.
Illustration
These are evergreen woody plants. Their height ranges from 3 ft to 82 ft (that is 1 to 25 m). It can reach up to a maximum height of 40 m. The primary branches are called pseudo whorls. Pseudo-whorls is the whorling of leaves around the main trunk. The bark of the plants of this family is characterized by scaly and fibrous texture.
The terminal buds of the plant are mostly distinctive by bud scales. The leaves of the plant are simple and flattened by an arrangement of leaves or phyllotaxy to spiral. The plants of this family are mostly dioecious that is male reproductive parts pollen found in male cones and female reproductive parts, and seeds found in female cone lies on two different plants. Few exceptional plant species of family are monoecious.
The seed cones consist of 2–5 scales. These scale fuses to form fleshly berry fruit on maturity. Those cones having 1 scale are considered to be sterile. The cone fruits are mostly red, pink, or bluish in color. These colorful and fruity beery-like fruits attract birds and insects. This helps in the dispersion of seeds by the birds and insects.
Sensitivity of Podocarpus
Podocarpus is highly sensitive and causes extreme allergies. The pollen grains of the plants rate 10/10 on the OPAL (Ogren Plant Allergy) rating scale. The female cone rates 1/10 on the OPAL scale. Thus it is called an ‘allergy fighting’ cone.
The stem, leaves, flowers, and pollen of the plant are toxic. They are cytotoxic which causes harm to cells. The side effects of cytotoxicity of plant result in damage similarly caused by chemotherapy.

How a Tropical Conifer May Hold the Key to Kākāpō Recovery
The plight of the kākāpō is a tragedy. Once the third most common bird in New Zealand, this large, flightless parrot has seen its numbers reduced to less than 150. In fact, for a time, it was even thought to be extinct. Today, serious effort has been put forth to try and recover this species from the brink of extinction. It has long been recognized that kākāpō breeding efforts are conspicuously tied to the phenology of certain trees but recent research suggests one in particular may hold the key to survival of the species.
The kākāpō shares its island homes (saving the kākāpō involved moving birds to rat-free islands) with a handful of tropical conifers from the families Podocarpaceae and Araucariaceae. Of these tropical conifers, one species is of particular interest to those concerned with kākāpō breeding - the rimu. Known to science as Dacrydium cupressinum, this evergreen tree represents one of the most important food sources for breeding kākāpō. Before we get to that, however, it is worth getting to know the rimu a bit better.
Rimu are remarkable, albeit slow-growing trees. They are endemic to New Zealand where they make up a considerable portion of the forest canopy. Like many slow-growing species, rimu can live for quite a long time. Before commercial logging moved in, trees of 800 to 900 years of age were not unheard of. Also, they can reach immense sizes. Historical accounts speak of trees that reached 200 ft. (61 m) in height. Today you are more likely to encounter trees in the 60 to 100 ft. (20 to 35 m) range.
The rimu is a dioecious tree, meaning individuals are either male or female. Rimu rely on wind for pollination and female cones can take upwards of 15 months to fully mature following pollination. The rimu is yet another one of those conifers that has converged on fruit-like structures for seed dispersal. As the female cones mature, the scales gradually begin to swell and turn red. Once fully ripened, the fleshy red “fruit” displays one or two black seeds at the tip. Its these “fruits” that have kākāpō researchers so excited.
As mentioned, it is a common observation that kākāpō only tend to breed when trees like the rimu experience reproductive booms. The “fruits” and seeds they produce are an important component of the diets of not only female kākāpō but their developing chicks as well. Because kākāpō are critically endangered, captive breeding is one of the main ways in which conservationists are supplementing numbers in the wild. The problem with breeding kakapo in captivity is that supplemental food doesn’t seem to bring them into proper breeding condition. This is where the rimu “fruits” come in.
Breeding birds desperately need calcium and vitamin D for proper egg production. As such, they seek out diets high in these nutrients. When researchers took a closer look at the “fruits” of the rimu, the kākāpō’s reliance on these trees made a whole lot more sense. It turns out, those fleshy scales surrounding rimu seeds are exceptionally high in not only calcium, but various forms of vitamin D once thought to be produced by animals alone. The nutritional quality of these “fruits” provides a wonderful explanation for why kākāpō reproduction seems to be tied to rimu reproduction. Females can gorge themselves on the “fruits,” which brings them into breeding condition. They also go on to feed these “fruits” to their developing chicks. For a slow growing, flightless parrot, it seems that it only makes sense to breed when food is this food source is abundant.
Though far from a smoking gun, researchers believe that the rimu is the missing piece of the puzzle in captive kākāpō breeding. If these “fruits” really are the trigger needed to bring female kākāpō into good shape for breeding and raising chicks, this may make breeding kākāpō in captivity that much easier. Captive breeding is the key to the long term survival of these odd yet charismatic, flightless parrots. By ensuring the production and survival of future generations of kākāpō, conservationists may be able to turn this tragedy into a real success story. What’s more, this research underscores the importance of understanding the ecology of the organisms we are desperately trying to save.

Plant of the Day
Saturday 30 June 2018
From the wet, temperate rainforests of South West Tasmania, Lagarostrobus franklinii (huon pine) is not actually a pine but a member of the family Podocarpaceae. This rare tree was growing successfully in the woodland garden of Brodick Castle, Isle of Arran, Scotland, enjoying the moist conditions. As the tree grows so slowly in the wild it has long lasting wood and has been used for boat building, but is now endangered. In Tasmania there are clonal colonies that are 5,000 or more years old.

#2405 - Pectinopitys ferruginea - Miro
Tumblr media
AKA Prumnopitys ferruginea, and originally Podocarpus ferrugineus. 'ferruginea' derives from the rusty colour of dried herbarium specimens. Miro comes from the Proto-Polynesian word milo - the Pacific rosewood (Thespesia populnea) found on tropical islands far to the north.
A podocarp endemic to New Zealand, growing in lowland terrain and on hill slopes throughout the two main islands and on Stewart Island.
It can live to about 600 years in age, and 25m in height, with a trunk up to 1.3 m diameter. Like other podocarps, the fruit is fleshy and berrylike, and spread by birds such as the New Zealand Pigeon.
Lake Mangamahoe, Taranaki Ringplain, New Zealand

Gabrielle Amodeo, PODOCARPACEAE / Dacrycarpus – ASTERACEAE / Pachystegia 2010. Image
Jill mentioned this artist in response to my flower installation. Interesting in retrospect since this whole relation to botanics. The process from my understanding was Gabrielle finely cut out these illustrations to install in the manner shown above. Accompanying this were the books she had cut from, which showed the pages lacey remains of an absent illustration. Super interesting stuff, particularly this play with the presence/absence and how they can be presented simultaneously.

History about the bush
Otari-Wilton's Bush was originally covered with podocarp broadleaf forest. The name “Otari” is Māori for “Place of Snares”. The forest was a good place for bird hunting. When the region was colonized by Europeans, trees were removed for timber, and to create farmland.
The first part of the reserve to be protected was a 7 hectare area of original forest that was fenced off from stock in 1860 by a far-sighted local farmer, Job Wilton. This became known as Wilton’s Bush, in 1906 the forest was gazetted as scenic reserve. Many parts of the current Otari-Wilton's Bush reserve have been designated as reserve by the New Zealand government and Wellington City Council. This includes most of the remnants of the mature podocarpaceae forest that once cloaked all of Wellington and the surrounding hills.
The forest area holds native trees that are hundreds of years old, like matai Prumnopitys taxifolia and rimu Dacrydium cupressinum, as well as tawa Beilschmiedia tawa, rewarewa Knightia excelsa and kohekohe Dysoxylum spectabile.
The plant collections that now form the native botanic gardens, were the brainchild of eminent botanist Dr Leonard Cockayne, who started developing this collections in 1926.
