Sweet tree man, whats up with the branch over the driveway, looks kind of low, did it fail? or is it just the picture angle?

What's the plaque say about it .... "Accepting quotes for firewood inside"

Awesome!!! I really admire that species, would plant one if i had the room...

Noticed the filenames on the pics. Did you do a monetary valuation on it???

Eric Frei

Yes, they want to know what it's worth in firewood and woodchips.

what a awesome tree, i like the way it go over the driveway, too bad if you really need to get a large vehicle to the house. is that tree protected or was it just saying what sort of tree it is

treekiwi

hey guys,
The current owner loves the tree and doesnt mind living with its querky habits... The low limb has grown that way, means you can only get a car or very small 4x4 under the branch lol. The plaque states that it is a protected tree under the notable tree register of nz.

Yes we valued the tree for its historical value as part of my diploma papers.
We used two valuation methods, ISA and S.T.E.M (nz standard) and these were valued for historical and cultural significance.

I valued the tree at :

S.T.E.M = $46,683.50
I.S.A = $52,300

Some valuation methods are very subjective, such as bernley which begins to reduce in value as the girth of the tree exceeds the mathematical parameters.

Impressive tree!!
What causes the discoloration around the big branches?
And can you tell some more about this species??
What area and climate does it grow??
Does it lose its bark just Platanus??

Eric Frei

Burnley method is in this post Monetary value| Tree Valuation Methods what do you mean about girth of tree affecting the result?

The results vary wildly. I'll reproduce an example i made.

Cuppressus Eucalyptus Brachychiton Poplar

Helliwell $167,500 $50,000 $270,000 $255,000

MCC $38,236 $14,000 $3,145 $10,096

Burnley $3,350 $9,335 $2,650 $6,125

Aus Std $13,650 $6,813 $60,843 $15,000

A modifier was developed to calculate inaccuracys that were made in the first draft of the system.
This means that now the system overall outcome is dramatically changed due to the modifiers having a big impact on girth measurements. The 'usually' high value mentioned in the document in the thread suggest that the values were in-accurate. It seems to me the modifiers dont work correctly, as shown by trev in his post with no historical significance was taken into consideration and very low final figures. I was under the understanding it was developed for valuing street trees.... Just my two cents...

Eric Frei

There's no "girth" modifier, only volume.... which refers to tree volume.

Attached is the modifiers, I think you have mis-read.

I stand corrected.... Your right about the volume modifier. I cant remember exactly what the drawback was but the volume became a problem as the tree became larger. I will have to do some research to find out why that was.....

treekiwi

Possible problems with burnley....

1. volume is compared to a tree avaliable in the nursery. it must be the same species for the correct comparison. What if the tree is no longer in cultivation? also the nursery tree must be over 1 cubic metre in volume, 3 nurseries many not have the correct size with means compromise and possible inaccuracys...

heres an example of what I mean by the volume argument....

Tree 1: Podocarpus totara

tree volume = 2,850.30m3 Volume modifier = 0.3
location = 1.0
form = 0.9
life expectacy = 1.0
Value of tree in nursery $26.44 per m3 total value = $20,347.72

Tree 2: Podocarpus totara

Tree volume = 4,401.02m3 Volume modifier = 0.1
location = 1.0
form = 0.9
life expectancy = 1.0
Value of tree in nursery $26.44 per m3 total value = $10,472.67


That is a difference of $9875.05!!!!! which should be the other way around, with the larger tree worth more!!! both trees have the same location,form and life expectancy.

Eric Frei

Well, that's bloody useless then! Even the Gunn's logging technique works better than that, of course a larger tree is worth more in woodchip.

Discounting the value after 100m3 of canopy volume means it's only useful for trees up to advanced mature nursery stock IMHO.

What about the Thyer method, how did that work out?

There's some big ones here, beautiful tree, they change colour, & can grow some very funny branches. [I'll try and get a pic of one near here next time I'm there, it's been on TV, but it's hard to get a good picture]

This is some info: Angophora costata - Sydney red gum

Sorry treekiwi, nice pics,

Done it

Lucky it was still there, the old house & everything else is gone including a few branches. Also a couple I saw on the way, pity about the wires, most of the big ones are in very bushy areas, hard to get pics.
