    here's a look at a range of fractures & coronets we've done over a few years........ .

    the "white powdery mould like substance" could be the mycelium of Laetiporus sulphureus a common brown rot decayer of willow. .

    Cheers Rich We manage a population of about 20,000 trees across a wide variety of situations so the work covers trees on roadside, parkland, secondary & ancient woodland. Certainly keeps the job interesting .

    I believe Einstein spent a summer of his youth walking amongst the urban woodlands of Württemberg to assess the decay and exposure of a range of street trees, after much deliberation and testing with a ball of string and very large Brätwurst he eventually came up with the hypothesis that...............'some' reduction of load is very much better than none .

    I don't imagine it's the 'oak' bracket (Inonotus dryadeus) I think it's a very early developing Inonotus hispidus, which if it is, is relatively rare on beech. I've only once come across the two associating. Hispidus is a white rotter. I have no knowledge of any failures of it on beech, so can't really offer any advice. Looks like its part of the group and as such would be part sheltered by the rest of the beeches? .

    A meet up for an Indian breakfast at some point then If you get the chance I'd be interested if you could get hold of the failure list for last St Jude's storm for the borough More so the species that went rather than exact numbers LTOA have it down as 336 with only 6 privately owned trees out of that number. Sounds like the cherries days are numbered. .

    Laetiporus decay right through, the removal of that amount of branch timber and foliage was done to lessen the end weight of long heavy lateral limbs, which if left would at some point snap out and probably take large chunks of the canopy with them.

    It must be just you, have you been tested recently ? Just played both of them here. It's the really old ash on the edge of the footy field by Lime avenue and the oak is on the corner out in the meadow opposite the stock pond and model boating pond. Michal's had a good scramble over both of them to test his knee out, no problems, things are looking good The oak is this one from post 59 http://arbtalk.co.uk/forum/tree-health-care/52839-light-reductions-6.html .

    I'd agree that it looks like the desiccated remains of Laetiporus Any evidence of Armillaria at the base? I often see this with street planted prunus, particularly ones that have been heavily reduced. If it was on an open space I'd imagine you wouldn't of even brought this up, right? Having been heavily reduced and still have good vascular health would appear to suggest the tree could be retained. Is it particularly exposed? Probably needs to be on a list for replacement, but a fair way down that list maybe? How's the general condition of the street tree population where you are? .

    Sorry about that, finding which tracks don't infringe on copyright across different countries is random to say the least Both play ok for me on PC and iPad What are you trying to watch them on, the Samsung? .

    3 miles from St Paul's Cathedral is not particularly deer territory A few muntjac, but they're not in evidence much. .

    Tree will pretty much be left as is Fred. If I'm still around when it becomes too unstable due to root/buttress decay then we will probably shorten the branches. The team that manage the conservation issues here like grassland habitat are a big part of the plans on this and others like it. .

    this Q. robur has given up the ghost but not before it had the chance to spread its seed The regen has been thinned out and the grass is being left long. Hopefully one of its remaining three proginy will will reach maturity. .

    four years on, this robinia is nearly getting there....... .
