Ficus virens transplant.

Treelore · 15th March 2008, 05:45 AM

Here are a few pics from the transplant. The tree was moved about 60m and rotated 90 degrees. will have some more of initial and post move later but are on different camera.

Treelore · 15th March 2008, 05:55 AM

couple more.Total weight came in at 160 tonnes.

TreeDimensional · 15th March 2008, 07:58 AM

Great job Treelore, Just one question, why did you rotate it 90 degrees?

Treelore · 15th March 2008, 09:21 AM

wasn't my call

Ekka · 15th March 2008, 04:09 PM

Thanks for posting, 160T is heavy.

I like to get the answer to these questions.

1/ DBH and distance to cut roots, like what factor was used.

2/ Soil depth taken?

3/ How did they cut the roots beneath?

4/ what did they move it on? A low loader etc?

Treelore · 15th March 2008, 08:34 PM

prep time unfortunately was limited, courtesy of developers. Compnay that actually did the moving was a Sydney co. that moved the figs for the Olympics. Iwas simply there to oversee arboricultural practices. ball was 8x8. 4 80 tonne jacks at each corner raised the ball for skid plates and 2 excavators and bulldozer pushed and pulled it into place. 90 degree rotation was unfortunate but necessary for it's new position as branches would have been in contact with abc. Multi stemmed dbh 7 leads 2.8 metres in sum.

Ekka · 15th March 2008, 09:50 PM

8m wide right .... so how did they cut the roots under there prior to jacking it up?

azrael · 16th March 2008, 05:33 AM

Treelore ... that is a very interesting job ... and I have the same q's as Ekka....

Quite a few years back there was a similar sized Fig (F.rubiginosa from memory) moved at Kiama (old Primary School).
I was an onlooker day the move was made ... peering thru the fence with another Arborist ... wondering if it would be successful with such a comparatively small root-ball ... and many many visble roots well outside the transplant root-ball.
That tree had irrigation installed for it .... and today you would never pick it had been moved ... no photos of the job though ... (pre-digital era). I'll pop down soon there in the next week or so and get some photos of that tree as it stands today.

Look forward to your other before and after photos ....

Treelore · 16th March 2008, 10:46 AM

The root ball was 6 ft deep. auger bits drilled holes under the tree every 600 mills for the length of the ball then steel rods wer placed in the holes and welded to I beams on the outside. there was little root mass at that depth because of shocking soil profile and anything that was, was lateral and cut correctly with saw. No root mass underneath.

This article is interesting ...
Two 100years old Figs at the Hong Kong Jockey Club .... were moved 32m and 57m respectively.

I wonder how they are in 2008 (13 years post-transplant).

Treedoc · 10th May 2008, 01:18 AM

HK figs looked good 2 years ago.

The fig you see in the images was done by Transplant Industries (Peter Wilds). Wouldn't have gone over $240,000 to transplant including all the aftercare for a decade. It was actually a smaller fig done with more soil than the one lifted using the Disney pin lift.

Peter is perhaps the best transplant engineer in the country.

I would love to know why rotating the tree is a shame. Ever seen a 1000 litre pot marked with north? Ever seen a lopped fig get sunburn? Where do myths like this start?

As for the trunk to root plate diameter ratio ... generally it is 10 to 1 but with figs you can drop that down as low as 8 to 1 or with some preparation and care 6 to 1 which raises another question. How does this compare with the British Standard at 24 to 1? More myths dutifully taught to sheep being let to slaughter!

Yes I have, and documented. It's called out in this thread, make sure you look at all the pics.

Absolutely not, and discussed. No sheep being slaughtered here thanks.

6:1 transplants most common with ground specimen nurseries, preparation is the key and so the after care.

There's some info on this thread Tree protection zones| Critical root zones| Critical Root Radius| AUSTRALIA

There is a search function with the forum that can perhaps lead you to some already charted territory. Also there's the professional area which is hidden, that upon entry will open further information with real live cases and documentation.

The preparation of a tree for transplant is very different to the treatment of a tree on the commercial development site.

Two entirely different scenarios, and for those of us who work with the trees and the developers it's a constant battle to give the tree the resources it needs, dead transplants would be major egg on the face wouldn't they?

Treedoc · 11th May 2008, 06:04 AM

Perhaps I am stupid for not understanding why the treatment of trees for transplanting or on a construction site isr any different. Surely a dead tree is not good either way. Perhaps Arboriculture is more than pruning, removing or transplanting trees.

Why not use the knowledge required in transplanting a tree and adapt that to caring for trees on development sites? Developers my find this financially refreshing. In any case why adopt a British Standard that clearly has a significant margin of error (over 80%) when calculating a protection zone unless it is to establish the benchmark at which an arborist should be retained.

If the latter is the case much of the document is crap, if the latter is not the case then most of the document is in error (crap). Not a good position to start from. Any Idea where the 12 times trunk diameter comes from in the 2005 British Standards. Ever questioned it and gone to that source? Ever found out where that souce derived the formula from? Most transplants get less than 6 months preparation time and oftem only days. Sounds like development sites to me.

I am sure that what you see in the Ficus virens is not sunburn but I am happy to be told I am wrong. UV rays certainly alter plant parts and in particularly leaves but I am not sure that we call that sunburn. In the same way that a tan is not sunburn. In fact the leaf uses a number of methods to reduce the damage from sun and in particular it uses chloroplasts. Do leaves get UV damage ... well yes leaves do but is the scald you see on them after a stinking hot day sunburn ... No!

For almost identical reasons the orientation of a tree in terms of UV damage is almost always irrelevant. Is it a myth ... probably since it seems to be devoid of any scientific basis.

The clear difference between transplanting a tree and protecting the one there is simple, it's called $'s.

The transplant tree dies and they spent how much on it?

The protected tree dies and Oh well, so what, no repercussions other than a blank spot for something else if anything at all.

Many times trees on development sites are marked for protection but there's no care for it, it's not mandated, so it starts to die or dies on the site. No loss as no bond. What did the developer spend on it? Nothing basically, the councils said it has to stay but approved plans to build, no "rules" on care for it, no financial impact if it dies.

Sure you could do all those "TLC things" to help it and reduce the TPZ but many times there's just builders onsite. So the difference is when you are transplanting you're there and "in charge" of care and making darn sure the thing lives. But many development sites dont do that for the remaining trees. That's up here anyway.

Here you go. What do you think of this pruning? Development site case study
