    just occasional I''m pleased to say Jon. Good call on the tag database .

    Think I posted this in the past but can't find it. Tagging on trees is so disrespectful and ruins the aesthetics of the tree and environment. Has anybody else had experience in removal success? Here from 4 years ago we tried a mild eco-detergent at first but eventually just hot water and scrubbing did the job. I'll post an update shot later this week. .

    Young Tom here having a go with the PD400 looking at a Lombardy with Perenniporia issues .

    Liking those a lot, may have to get me and me youngest giving that a go Thanks for posting sean .

    Certainly would be interested in seeing the images Scott I've little experience of seeing subterranean root damage on coniferous trees & how they respond. .

    Thanks Scott ppe has been a work in progress to be honest. we've gone from full & half face 3m respirators, disposable dust masks, clear & mesh full face visors, safety goggles, safety glasses I've pretty much settled on the 3m half face respirators, safety specs and helmet visor as going at it like a Stormtrooper is both unpleasant and a hindrance. The risks of silica dust and flying objects are covered by this level of ppe & with that going through a risk assesment, checking on good practice & agreeing a safe system of work should suffice. I think if its possible, with a mind to having a SSW in place, the best line of protection is taking shifts between operators and if solo taking ample breaks away from the task. Also believe its important for the rest of the team to be masked up if they come in to the air contamination area. .

    Hello Marco, thanks for the feedback I wasn't around for this one, I just edited the footage together. Perhaps one of the other guys may explain what was discovered. The opportunity was partly about letting the FdSc work placement have a go on the airspade and also look at some filming options. My understanding is that there appeared to be a reduced presence of roots from the trunk in the area where the footpath crossed the root plate and that the Meripilus had more than likely killed off any lateral roots that had been there in the past. This seemed to be reflected in the associated canopy parts where there was some die back. We intend to block then re-route the path, and also carry out de-compaction .

    I know this will sound a bit arsey but I won't be sharing the readings of the penetrometer tests or the last 5 years bud extension growth until the research project has been submitted for marking. I'm sure being on the level 6 you can appreciate that. The mulch went down in 2008 then topped up in 2010 & again in 2012 the first reduction work was in 2009 & then again in 2013. The picture is of Nick measuring the distance between terminal bud scars over the last 5 years growing seasons. .

    Mostly nodal Guy, as shown in the cuts in this video, but there were a couple of internodal cuts not in the film. [ame] [/ame] .

    What do the buttresses 'sound' like Guy? .
  11. David Humphries
    helping a friend with a compaction study comparing readings from different sites on veteran trees that have been mulched. Here we're using a Penetrometer to measure compaction inside and outside the mulch bed. .
  12. David Humphries
    Great precision down to 0.1mm scale & a snip at £25 dialMax Vernier Dial Caliper: NHBS .
  13. David Humphries
    Monitoring for now its had reduction, bracing and mulching probably needs a rest .

    Surely the whole purpose of people going on holiday is to be on Arbtalk more than they normally would, no ? Will be interesting to see how many people do sign the petition .
  15. David Humphries
    monitoring these cracks between the sinuses with a calliper, to see if we need to reduce the canopy of the veteran torminalis any further than we have already .
  16. David Humphries
    put up something similar a week or so ago didn't seem to get anyones attention http://arbtalk.co.uk/forum/tree-health-care/72462-rbg-kew-operational-budget-under-threat.html .
  17. David Humphries
    as if we would .
  18. David Humphries
    Posted this in the tree health care forum already, but also thought that it should go here. .
  19. David Humphries
    Impressive .
  20. David Humphries
    Certainly got a touch of the surreal about it .
  21. David Humphries
    Not the same scale, but just as impressive. Really healthy More interesting features than Frithsden, also without merip in attendance. .
  22. David Humphries
    Been long over due to pay my respects , especially as I've been close by on many occasions. It was your thread, plus talking to Nod & listening to Ted at Conference last year that made me think that I needed to get orf me arse an go visit .
