Can anyone please tell me about the difference in properties of "paddock jarrah" versus "forest jarrah" ?
regards,

Just my best guess - paddock Jarrah would be likely to have more limbing.
If I am wrong feel free to let me know.

What Doug said. Also common in historical sources talking about ship building timbers - they wanted field grown Oaks for ribs and brackets because of the limb branching and forest grown oaks for beams and planking.

my suggestion is to
make the post with the photo(s) you want to retrieve.
after you have saved the photo(s) to your hard drive, go back and edit the post to either delete it, or make it "null" (including a comment that the deleted / edited post was created to retrieve a photo)regards from Alberta, Canada

The main difference you will find between the 2 is colour of timber.
Paddock jarrah will rarely be the characteristic dark red of jarrah. It will normally be a lighter pink for a few reasons... It has no competition with other trees for moisture so it grows faster. It has less pests to deal with. And it will quite commonly get a nice dose of fertiliser from the farmer that left it behind.
A lot of the old sawmillers can tell you where a jarrah tree was from by the colour of the timber. The soil in which it was growing greatly determines its colour, not necessarily the trees age.

In my experience, from a general woodworker's position , meaning someone who is interested in dry, milled, workable wood and not that of something super specialized, forest grown is almost infallibly superior. The color is darker, the grain is tighter and more stable, it's less prone to tearout, etc. Red Cedar is a great example. Probably more than 90% of what's out there today is inferior to what was there before when it was coming from forests.
This is a generalization, but I don't necessarily think it's a gross one.
Cheers,
Luke

Photos of paddock jarrah
The following photos of paddock jarrah confirm what nifty and Luke say.
I have a son driving around Oz, currently working in Augusta in WA, near Caper Leeuwin lighthouse. Cape Leeuwin is the furthest southwest corner of the Australian continent.
He found a sawmill up Margaret River way, and sent me some paddock jarrah boards for a Xmas gift. Have just finished dressing them. Definitely lightweight, open grain, and pinkish in colour

I agree with Nifty on the general causes.
Some trees may have different colours growing in the same area of forest but they are just on opposite sides of a hit,l which is once again a rainfall effect
If the tree does not get enough water, as well as growth changes, it changes the mineral concentrations in the water that the tree sucks up.
As well as water, pests, and fungi act as additional stressors.
One of the few defences a tree has to pests and fungi is to make more resin and this also changes the wood, especially its colour.
The older a tree is the more chances it has had of being stressed and so this is why many old trees have a deeper colour.
There's also the factor of tree shape and exposure to wind leading to denser/harder wood production under branch unions.
Because big jarrah trees take a long time to grow and early manual clearing practices there's often a confusion between whether a tree has spent its time growing in a forrest or in a paddock.
When clearing methods were limited to manual labour, very large trees were often just too time consuming to bring down and grub out the roots so were often ringbarked and left in the middle of cleared land, and crops grown around them.
I remember as a kid in the 1960's going to watch my tree faller dad on weekends felling these old monsters that had been left behind when the land was first cleared many decades before.
The live trees may have spent hundreds of years in a forest and 10s of years in a paddock.
Some of these trees had the choch-liest looking jarrah I had every seen I cringe to think that and it was all bulldozed into piles and burnt!
