We found a great example: a Paperbark Birch or 'Betula Papyrifera', of which there are many large specimens around the forests in this area of, but oddly not many that I've found growing while of this medium size or smaller, for bonsai really... This tree was literally 'run over' by county trucks that clear the trail, and shows deadwood and scarring down one side from this. Other then that, it also has nice movement in the Trunk, quite healthy after I checked the tree over - we decided it would come home with us.
Next time - I will take more pictures 'of' the tree excavation, I was short on battery at the time, but it was a long process. We came away with quite a good amount of feeder roots, as this tree had also grown in a sandy/rocky area along the riverbank/trail so I got 2 pluses for one out of this great tree.
Largest material I have at this time, great care will be given to maintain this tree and help it to grow used to container living.
Good girth with nice movement.
Can see the deadwood area from where it was run over and 'pushed' sideways on to the ground as we found it. Nice carving area later on.
Good shot of the ex-foliating bark, I helped it along a little to see if I could find any buds further back on old wood and...
I found quite a few, this one is even close to the deadwood area.
Many buds in this area near one of it's bends.
A few more on this side as well.
Quite a healthy tree, it will receive good nutrients and lots of them as I have it in 80% non-organic porous soil, with slight organic additive to stimulate fine, radial, root growth.
