Photo requests

[Amelanchier]

I'm putting a document together to briefly explain tree biomechanics and would like some lovely photographs to illustrate a few points - so as I'm paying the price now for never buying a good camera, I though I better cast my net in the webs best waters.

 

I need photo examples of:

 

• The axiom of unifom stress - perhaps a nice bit of adaption around an object, preferential callus on a pruning cut etc.
   
  
• The law of the minimal lever arm - I'd love a classic topped out pine!
   
  
• Self optimisation - I have a few of these but some nice reaction wood shots would be helpful.
  

 

Thanks in advance gang.

i am on it tony, i am glad you put the explanation because i hadnt a clue what the first part meant, now reaction wood, is that when if a branch/limb gets too big or week then the trees puts on more growth around it??

[Amelanchier]

Thats it dude. When the tree puts more wood on to strengthen a part thats overloaded. I've got lots of phone cam images but they won't stand being resized.

i have an ash to work on tommorow that needs a limb off, nothing huge but there is reaction wood, almost like a spli in the fork. easy to see in 30 year old ash, if you want mega reaction wood then there is a larch up the back of my house that is 4 times the base to what it is 6 feet up, it is almost square if you know what i mean, i can soon get a pic of that. look up dave d thread about stones in walls, he had an amazing pic of a dyke embedded in a beech and bob has loads of topped chrimbo trees in his gallery lol

Here is a nice one from the Quantocks that shows some self-optimization/lever arm.

 

Hope this is the sort of thing?

I love the third shot, the way the tree uses objects to lean on!

 

There is a Poplar round the corner from me leaning on a brick pillar like its resting an elbow - I'll get a picture for you today Tony
