Interesting Biomechanics

[Cassian]

I appologise my post (above) was in reference to Posts 1, 9 & 10 at the start of this thread.

 

Regards Cassian...

The beech pictures are exceptional, I have recorded a number of instances where Gums (mostly Corymbia) have produced substantial grafts above V forks. In the case of the beech did you observe sign of potential mechanical constraint at the base of the grafted limb? Judging by one of the photographs there looks like signs of inclusion.

 

Wonderful find - Best regards Cassian

 

Thanks for the input Cassian.

 

This is a fantastic tree for sure, and we have the good fortune to be able to manage & enjoy it, the fact that it's off the beaten track just adds to it's presence.

 

Where I work at Hampstead is not particularly over blessed with big numbers of amazing trees, but there are a few very special and intriguing ones.

 

Next time you're over give Andrew a shout, and I'll happily show you around.

 

If you ever get the time, there'd be plenty of members here pleased to see more of your papers/photos etc

 

Here's a few more shots of the Beech from the other side.

I think the attached will be of interest, these pics are a sample from a past article of mine on natural grafts of Gums (Corymbia & Eucalyptus).

Corymbia tessellaris - Moreton bay Ash.

One of the mechanically most robust gums of all in SE Qld - have never seen a limb failure or signs of a past limb failure on this species, even with difficient mechanical form it stands strong.

This species was almost an exclusive survivor of the Brisbane 2008 Super Cell Gap Storm.

 

Check out the multistemmed Moreton BayAsh with a living prop and its occluded past leader, I love the tenacity of the gum. Observe the braided reaction wood on the elongated propped stem.

Hello Cassian,

 

those shots are truly fascinating, thanks for posting.

 

I was dissapointed not to get to your recent lecture here in the Uk, Andrew speaks highly of you.

 

Do you intend to revisit in the near future?

 

 

Welcome to Arbtalk by the way.

Hi David Sorry I did not respond to this, only just found it. I appreciate your encouragement. I have not made much time to explore Arb Talk, though am starting to make time now. I must say I am impressed at the level of Arb brain that is common to this site. Cheers Cassian...

David - also I expect to be back in the UK soon. After nearly 20 years of being downunder I am returning for a year or two. I am keen to attempt the RFS Prof Dip. My email address in naturaculture@live .com.au if you would like to connect.

Already noted Cassian, Andrew gave me the heads up.

 

Good luck with the move, I'm sure we'll get in touch via one platform or other.

 

Oh yeah, make sure you don't bring us any Elm Leaf Beetles hiding amongst your luggage when you come over

Hello Cassian, that's a fantastic subject shot.

 

Has the occluded past leader been prunned off at some point or is it the remnant of a failure point?

 

 

Great elongation & support occuring.

argh so this is the imfamous cass!

 

Shall be bumping into you at some point
