    Pipped to the post by Daltontrees 👍

    Considerably more than 100 words but should this enlighten you! http://publications.naturalengland.org.uk/file/2255878

    It might be Oxyporus populinus. Hopefully David Humphries or Tony Croft can offer their thoughts?

    In a thread some time ago, Kev Moore highlighted the prevalence of people with dyslexia within the arboricultural industry. So I thought the following link could be helpful to any of those arbtalkers that might have difficulty reading: Dyslexie Font: The dyslexia font which eases the reading It is a website where you can download a font that has been developed to aid dyslexics with reading text either on screen or on paper. I downloaded it yesterday and did find it a little easier to read than regular fonts. I would be interested to hear how others find it. Paul

    Very interesting, thanks for sharing David. Hopefully the disturbance of the soil in the root zone will limit the honey fungus. It will be interesting to see if it reappears next year.

    Robinia pseudoacacia - common name: Locust Tree

    It does appear to be an old pollard. Just out of interest are the Ganoderma brackets on the same side as the wound/stub of the failed stem? It is difficult to see from the picture but based on the fact that one stem has already failed, it might be worth carrying out a minor crown reduction to reduce some of the end-weight of the remaining stems. If there is a significant target you could go one step further and map the decay with a Picus.

    Do you have a photo of the whole tree that you could post? Or even just the crown? It would be helpful to gauge the size and shape of the crown and the vitality. Doubt a crown thin is going to be of any benefit. It's unlikely to significantly reduce the wind loading and will limit the resources available to the tree for defence/compartmentalisation. Is there a significant target?

    Based on your original post, it sounds like the RFS certificate in arboriculture (Level 2) is exactly what you require. The purpose of the course is to provide practitioners (arborists) with the theoretical knowledge for work they do. For example, it covers: the principles of tree surgery operations, the interaction between the soil and plants, woody plant physiology (how trees work), tree planting, health and safety & a little on trees and the law. In my opinion all professional arborists should have, or be working towards, achieving this qualification.

    I managed to find the Celox as a gauze (so not loose granules). You just pack the gauze into the wound. The thinking being that it's easier to clean out of the wound once you're in the capable hands of the health care professionals. Fingers crossed none of us arbtalkers need to find out!

    Interesting question. I assume you want to know how much of the roots need to be retained in order to maintain the stability of the tree? If that is the case Mattheck's graph showing 'root-plate radius/stem radius plotted against the stem radius from field studies of wind thrown trees' in 'The body language of trees' is probably going to be useful. However, this applies to living trees, so the wind load would be much higher than a dead tree. Using this approach might work if you are thinking along the lines of trenching for the installation of utilities etc. However, if it is for a structure or similar to be constructed near to the tree, I would allow for an area equal to the height of the tree as an exclusion zone.

    Hi David, I will be there on the Monday and Tuesday. Are you going?
  13. Paul Melarange
    Actually I think you are right Chris...oops That will teach me for relying solely Alan Mitchell's 'Trees of Britain & Northern Europe'. Nomeclature changes at such a rate, it's hardly suprising that his book written in 1974 is incorrect. I should have known better Apologies for confusing matters
  14. Paul Melarange
    I wouldn't say that you were caught out. Yew is a Taxad (Order Taxales), not a conifer (Order Coniferales). So you what you said was correct! 😀

    Hi Nick, I did the course last year. I found it very useful and would certainly recommend it. I also did the follow up subsidence workshop this year, which provided good revision as well as some welcome help with a particular case that I was involved with at the time. The course was attended by both consultants and Tree officers (probably half and half). Give me a call if you require any further info. Best regards Paul
  16. Paul Melarange
    Thanks for posting this Nick. It's something I hadn't heard of before. Hope the new job is going well 😀

    Hi David, Yes, In fact I asked him that exact question. He seemed to think that Mycorrhizal fungi would colonise the soil quicker than fungi such as Armillaria. However, I would like to see the evidence behind that statement. I imagine that a healthy rhizophere i.e. rich in beneficial fungi and bacteria could have an antagonistic effect against fungi such as Armillaria. Hence why Trichoderma seems to be a possible control. We got onto the subject following a demonstration of the new 'Arb-ex' compressed air lance. As you know Glynn has researched the effect of 'air-spading' on Armillaria colonisation of tree roots and root collars. Ted Green has always been sceptical of 'air spades' because he thinks they destroy the mycorrhizal fungi colonies. That prompted me to ask which fungi come back first.

    I'm guessing it was injected using something like a 'Terravent'. If the soil around the Yew tree is heavily compacted you'll need to address that before adding any amendments. If it's not too compacted (maybe it's a sandy soil?) then you may get away with just making some drainage holes with a fork or corer and watering it in using a watering can.

    Application of sugar solution provides an immediate supply of carbohydrate to the roots. This can stimulate fine root growth as well as increase fungal and microbial populations in the rhizosphere. More mycorrhizal fungi = improved nutrient and water uptake.
  20. Paul Melarange
    I attended an Arboricultural Association meeting at Reading University last Saturday with Dr Glynn Percival. He recommended application of a sugar solution at a rate 30-50g per litre of water per square metre of ground. It should be applied from the trunk out to 1m beyond the drip line.

    I've just watched some of their other instructional videos and they are really good; very clear and informative. It seems like it is just that one that maybe needs to be revised.
  23. Paul Melarange
    I agree. What a strange 'instructional' video though?! You would have thought that they might have selected a branch that enabled them to demonstrate easily the points that they wanted to convey, rather than cutting a branch that was so awkward that they couldn't even make a correct final cut! Lets all donate so they can make more crap videos 🙊
  24. Paul Melarange
    I think you should go for it. What have you got to loose? Sounds like the tree has entered a mortality spiral and will die if there is no remedial action carried out. Maybe remove the concrete, then do some soil analysis such as measuring bulk density and texture. That way you can decide whether mulching will eleviate any minor compaction that has occurred or whether decompaction with a compressed air lance I.e air spade is required. Applying a sugar solution out to just beyond the drip line may also help.
  25. Paul Melarange
    👍 That's good to hear. It's a book that would be of benefit to most arborists regardless of whether they work on ancient and veteran trees or not. It includes lots of detailed information on tree biology. Everyone should own a copy 😀
