Sweet chestnut? That'll be the tannin.

C'mon Ed. Don't pick on the little guy, we've all got to make our money.

Sent.

Then Mrs Miggins better appeal showing evidence of her commercial need to hack her tree!

We recently TPO'd an apple tree when planning permission was applied to put a driveway through half the RPA. Trees still there. Driveway isn't.

Diane, I have a bit of coursework that reviews the pests and diseases of Ash if your interested. If you PM me your e-mail i'll send it to you. Might even have some piccys, I'll have a look if I get a chance!

Careful - Only fruit trees involved in the commercial production of fruit are exempt. That apple tree in mrs miggins garden can be TPO'd.

I can vouch for Mardale. I own pile & pertex buffalo style pullover top and have worn it while working for over two years. Its taken a right beating and its all still there.

Damn I'm rude... Thanks to Mike at Prochip for the polesaw Thanks to Iain at Oakdale for the Krab Thanks to Steve & Co. for organising the whole thing!! Sorry.

I would draw your attention to section 5 within BS5837 "5.2.4 The RPA, for each tree as determined in Table 2, should be plotted on the TCP taking full account of the following factors, as assessed by an arboriculturist, which may change its shape but not reduce its area whilst still providing adequate protection for the root system. a) The likely tolerance of the tree to root disturbance or damage, based on factors such as species, age and condition and presence of other trees. (For individual open grown trees only, it may be acceptable to offset the distance by up to 20 % in one direction.) (See Note 1 of 11.3.5.) b) The morphology and disposition of the roots, when known to be influenced by past or existing site conditions (e.g. the presence of roads, structures and underground services). c) The soil type and structure. d) Topography and drainage..." Whilst this is the guidance, I would talk to your tree officer. It will come down to his decision essentially so if you can establish a comprimise regarding the extent of a the pollards rpa then all the better. Do you have a copy of the BS?

Nope - as above.

Put another section on it and you could hit the bells from the beer tent!

From the ground mate!!!

yes mate!

Could have done that with my new polesaw! Cuts might have been a bit wierd but hey!

Polesaw came today. Its 'uge. Crown lift-tastic! If you want to borrow it for the comps steve I'll clear it with Alex!

*cough cough* <-------

Indeed, interseting stuff and is referenced in the doc posted in another thread - http://www.oca-arb.co.uk/pub/journal_of_building_appraisal.pdf However, not really anything to do with the direct action of displacement of a wall by incremental growth.

Well the bre document really just shows that light pruning doesn't really do anything to affect moisture extraction. The document below (too big to attach) makes the point that if a tree is definately the cause. The only solution is removal. http://www.oca-arb.co.uk/pub/journal_of_building_appraisal.pdf Concrete rafts -exactly! Engineer the problem away, British engineers are supposed to be among the best in the world. Even correctly depthed foundations would solve it.

In answer to the original question. Not a fact! I can see the reasoning of the TO, with regard to Shigo's concept of root to shoot ratio. i.e., the tree strives to maintain a (near) equilibrium between roots and shoots. However this refers to fibrous / feeding roots which are unlikley to be the ones responsible for the displacement of the wall. The displacement, if I understand the situation correctly, is due to the annual incremental growth of the structural roots of the tree. And if the tree is close to the wall - the annual growth of the root collar / flare. Imagine the implications for tree stability if a 25% reduction resulted in a similar percentage loss of structural roots!!!

I knew there'd be a logical reason - nice shots

What is that anyway? DED elm?

Saw got stuck? Doesn't explain the chunk though.

Dammit - explain yourself man.

What's going on in your avatar pic? Is that chunk stuck in the fork? What's with the saw? What de bloody ell ya playin att fella??
