Treeation

ditto

Doesnt look like Meripilus as it grows in tiers and has pores not gills.

Im with Paul on this one and the tutors for the link you showed dont really seem to have specialist knowledge on Arboriculture. Im just finishing Level 4 off with Treelife and would highly recommend them. Andy's knowledge is brilliant and has been a practical arborist for 15 years plus a many years of arb consulting and lecturing so you are getting the real deal!

Id go with that!

Another classic summer branch drop at my local park. Large horizontal oak limb failed out of large mature oak. No decay present at breakage.

Is it Yew?

I would go with this advice, IMO it will make you a better tree surgeon in the long term. Working for a good size firm will teach and install safer working practices for the future and less pressure. There will be more expected of you in the subbie world and although you have the quals you will undoubtedly benefit from at least 2 years experience working as an empolyee before picking up enough experience and speed to enter the subbie world.

U can download them off arb association website

Good tips Gary!

Thanks Armybloke, these look really interesting I have downloaded both and look forward to reading them when I get some time

I think you should get an arb consultant to come and have a look and advise as it doesnt sound like a striaght forward matter, Wet cavities shouldnt be drianed as the anerobic conditions prevent decay from advancing. Will be interesting to see pics

I guess it would make sense to, wouldnt have fancied my chances of being in the HC though! Although, I had prescribed some minor pruning....l think I dodged the bullet there!

Hi, yep pretty sure it was plain old hippocastanum. Didnt look like it had broken off at a graft union. Just looked in Body language of trees and Matheck refers to the "strangler snake in a ground hole" that looks remarkably like the HC failure.

Yeah for sure!

Yes a relief for sure! as you say was not foresseable so all good

Interesting point as ISA state "Research has shown that trees planted too deeply are more prone to developing girdling roots than those with trunk flare exposed"

No worries, seems like it was a ticking time bomb, does reinforce the need to inspect nursery stock and only chose good quality stock. I guess this tree was doomed ever since it was planted out.

So, here is a medium size horse chestnut I inspected only earlier this year. The context of the tree is in a common in a public open space. There has been no visisble signs of any ground works. It had some bleeding canker present on trunk Pseudomonas syringae pv aesculi but generally crown was in moderate physiological condition and the structurally moderate condititon. I had advised to remove some major dw and reduce a scaffold with a compression fork under a low priority as the tree has a desire line running under its crown. Other than a slight lean, it had no other visible defects. Yesterday, I discovered it had failed at the roots and collapsed onto the ocassionally used desire line. No one hurt or nothing broken thankfully. I went to have a look at the base expecting to see root decay but actually found none at all. There seemed to be no tension root and very minimal broken, structural roots flaring from the root collar. I took a look in the corresponding root pit and found an arm sized root encircling the pit (see pic with yellow lines) which would have been girdling the trunk below ground level. So my theory is poor nursery stock - pot bound with girdling roots that prevented an adequate structural root system from developing hence the failure....any other thoughts anyone?

Well said!Im with you on that one!

Fade out - Radiohead

Certainly the main trunks and scaffolds are obscured by ivy so girdling it will have light and safety benefits in this circumstance

Hi the £5K was for part time learning not long distance

Sorry meant Alnus cordata italian alder

You sure its not Alnus glutinosa?

Yep, I know what you mean i just have a habit of calling them planning apps but thankyou for explaining
