Found my top anchor that makes SRT efficient and safe (Thanks Boel!). Old posts about pinto pulley top anchor to be found here.
Everyone loves to climb a gum tree (also known as Eucalyptus). They origins from Australia (where thousands of varies are growing, only hundreds has escaped the borders).
Rainy day in a no-friction tree. Too easy is not fun anyway.
Extremely slippery when wet. Fagus sylvatica is nothing compared to this lack of friction. A dry day it’s heaven, big soft forks everywhere, spreaded crown to swing around in.
It’s also quite nice wood to work with. As in this fell over a solar panel.
How windy is Wellington really? Well windy enough to blister off the buds on the wind side, making it hard to give the tree an even thin. Also you always have to keep the strong winds in mind when you prune, a lonly branch easily breaks.
Guess which the wind-side is.
The umbrella in the foreground gives you a hint about the size of this tree.
1000 years ago New Zealand was populated by the Maori people, which origins in Polynesia. They were strongly connected to the trees, both through religious beliefs and practical needs. Medicines, foods and tools came from the trees. Therefore, does all the native New Zealand trees have a Maori name.
Not highest (32 meters) but fattest, 16 meters circuit. Just as with our old oaks, the crown seems to reform itself.
In the forest of Northland, the giant Kauri trees grow. When facing a trunk that’s more than 16 meters circuit it’s understandable that people see it like the Maoris – as a god.

Weight reduction of Pinus Radiata over a road in Wellington.
These huge pines were growing close to a road in Wellington. During one week we were closing the road of to reduce the weights on the big limbs.
Since the growth season is longer than in Sweden tree trunks quickly grow wide. Even 15 – 20 meters up the stem is quite thick. Windy days, which is most days in this city, located on the very south tip of the north island, it feels like clinging to a sailing boat mace. Big hills rapture the wind streams and capture the clouds giving the rainy and windy climate.
Pinus Radiata, that origins from California, was planted at New Zealand for the timber. The wide, tall trunks are ideal for forestry. But sadly no one thought of planting sterile trees. The lack of natural enemies made it easy for the fast growing species to spread. Pinus Radiata is now threatening the native forest and trees. (The native forest has already been cut back to give room for browsing mammals as sheeps, cows and deers, brought here by Europeans.)
The cones are attached hard to the stem, almost like a branch. They are eating throwline.
Up in this pine, I saw a Kaka, this native bird, looking like a brown parrot has been reestablished and seem to be well off. Some complaints that it eats the bark of non-native trees has been heard.
It’s left to see where this copy paste experiment we do with the ecology is going.
I mentioned the Pohutakawa before, but it’s a tree that keeps fascinating. On the stem, it grows aerial roots to drag moisture from the humid air. This one in Wellington city probably lacks water from standing in the hard surface surrounding it. The roots hang like big beards from the stems.
Pohutakawa closely related to the Rata. To differ the two, look on the underside of the leaves. Pohutakawa has lines, but the Rata leaves is covered with dots underneath.
First job since arriving in Wellington. Climbing a redwood to remove a broken branch.
Sequoias has surprisingly badly attached branches, often downwards leaning. You have to attach close to the trunk and not too thin.
Thanks Craig for the pictures!
During the three weeks I worked in Christchurch this was definitely one of the most unexpected days.
We often worked in Hagly park and neighbouring botanical gardens, so it wasen’t such a long step into the greenhouse.
This day I started by cutting an unbelievable clingy and thorny Bougainvillea (pink flowered) in the greenhouse. I needed to hack it away from the construction to be able to anchor into it. This plant also grow wild in north New Zealand.
Next tree was a Ficus (albert-smithii) with very delicate branches, not possible to stand on or pull. Therefore I was hanging in the air above it and very carefully cutting the tips. A common problem in greenhouses is the limited space.
Thanks to Devon and Lee for nice days in Christchurch!
First week I got up this dead gum tree (eucalyptus). Not native but still Pacific, orgin Australia. (Thanks for the pictures Lee!) Last picture gives a hint why they are called gum trees. There are hundreds of varieties of those in New Zealand and tousends in Australia. They are often very beautiful.
Arriving in Christchurch I got surprised how many trees I recognised. Birch, elm, oak, ash – all imported by the British.

I learned that they grow quite different here, due to the long seasons and generous sunlight. Oaks becomes thinner and taller and are more likely to fail, the quick growing wood has less lignin.
Small differences means a lot.
Arrived in Auckland on Friday night. Today I been at Waiheke island, where i meet a carpenter and woodartist who teached some facts about local trees. (Thanks Jeff!)
Most trees has Maori names. Pictures above show a Pohutukawa tree. This has extraordinary strong wood, thanks to wood fibers growing in a wave pattern. I would guess it’s even stronger then oak.
Another amazing tree is kauri, witch I haven’t been lucky to see yet. Sadly it’s treathend by a die back disease, maybe similar to ash die back? I will look into it. And get a tree dictionary!
New Zealand has been isolated for long and lots of the naitive life lack resistance from spieces comeing in from abroad.
20-21 may the swedish isa chapter was held in Uppsala. Out of four women, all With longer experience and more comps done then me, I was the thired in workclimb and rescue.
Between the masters, Veronika and Boel
Thought it was a pretty neat rescue plan, rope wrench srt up, with new system and rope for the casulty on my back. I got time to throw the rope down and secure my harness to Dolly.
Then time was up. To much fiddling around when I reached Dolly. Have to keep my mind clearer next time, and practise as well.
Thanks Robin for the pictures and everyone for support.
Any thoughts of how to get a smoother footlock is welcome. (I want to do clicker training.)
During the leafing we do less pruning and more fells. So I learned some new things. Above you see the “safety belt method”, useful when you don’t want the stem to jump and bounce on the ground. (This birch was standing next to a house.)
This way we could lower the branches away from a step hill. In the tree beside the one we are working on I put a rigging anchor and the line goes over to the tree that’s being felled. The climber put a sling around the branch and a carabiner that’s hooked to a pulley. The pulley sits on the line and make it run to the middle of the line.
Also made a nice ground fell the other day, heavy leaning pine over road. Made it go the other way with 3-1 system, stalp and a wedge. Better safe than sorry and it came down super smooth. (No camera that day.)
