Interesting Biomechanics

[sanny]

a came across one a couple off weeks back wish a took some pics now damm it looked well wierd

Very cool pics, when I did my cs39 we did a big beech that had branches fused in a complete circle.

Another Beech from work, this one a multi stemmed probable pollard .

Grafted branches all over through out the cannopy.

 

Are these trunks self bracing, or is that statement really as stupid as it sounds ?

Doesn't sound stupid to me. Sounds like an example of adaptation...

 

Maybe this propensity for grafting crossing limbs which allows larger limbs (that would otherwise fail) to be sustained, has give Beech an advantage???

 

I would suggest that if it is an adaptation, it would only be exhibited in longer lived species where such a protracted means of retaining an investment (i.e., a branch!) would have a value. I wouldn't expect to see such an event in a pioneer species...

I saw it on a large Silver birch which I haven't seen before and never took a pic

 

BTW, I've seen a silver birch before , I haven't large grafting on one

Oak adaptation & canker

 

Possibly formed originally as compression wood, layed down to combat subsidence or fracture.

Bacterial infection causing canker of the above.

Quercus with unusual trunk.

Crazy arsed Oak there Geoff.

 

Sweet Chestnut which almost succumbed to a Phytophthora infection, which eventually killed of some of the roots and associated butress.

 

Hanging on and regenerating replacement roots.

One of the most well known Trees at work.

Got hammered in the '87 Gales, and became self pollarded.

Now has 20' regrowth on the original scaffolds.

Will possibly retrench soon.

 

Came across a couple inside this morning, complete with guitar.

Alas no shot.

 

Amazing Tree

oak tree on a road junction,soil has been washed away over time, I think!

I may have to post pics in 2 batches so please persevere!
