No loctite for me, but I think its a good idea. Might start doing that!
-
I hear that brother!

Good question. I'm not sure. The decay in the stem had moved up toward the top from the branch pullout, I think it had been decaying for a while, the photo showing the wall thickness gives a clue... The beetles (or something else) had picked the decay clean at that point. Moving up the stem they were just settling in. I'd love to know example timescale for that kind of interaction. Oh I noticed that they didn't move down the decay column, maybe it got too wet when it rained? As for the rate of discolouration moving into limbs, I think is down to the branch protection zone, which I assume works both ways. Funny old game, eh? Its nice to have somewhere to waffle on about your day! ;D
-
Er...we improvised (we pulled quite a bit of top off with the GRCS, in a half the tree kind of way!)
-
Steve, yeah not bad considering, some evidence right at the top of short annual shoot elongation and smaller leaves. It had been slightly reduced at some point in the past 5 years, so maybe the really crap stuff was removed.
-
Hi edenarb, there was discolouration of the false heartwood in some of the limbs. Its hard to see on the photos but its there.
-
Dunno. I think it was dropping leaves in a gutter.
-
Thickness of the remainder of the stem at the cavity. Now why didn't I want to climb it? The stump cut showing "zones of antagonism" (nice one steve!) Some areas of white rot near the Gano. Little pockets of soft rot near the Kretzs., and nowt from the Merip. (Unsurprisingly!!) Oh and a close up 'cos its pretty.
-
First of the stem sections, mmmmmm nice White rot being eaten by lesser stag beetles.
-
Halfway through rigging out the canopy...
-
Oh the joy. Big beech by a road. With Meripilus, Ganoderma and Kretzschmaria. Plus big cavities from old branch pull-outs. With a platform that isn't big enough.
-
Nuttyarb, Cheers for the reply. I've specified many tomographs but was just wondering whether the concrete was a problem. I understand its all in the interpretation, my concern was related to the possibility of such a large proportion of concrete adversley affecting the results to such a point that they become unreliable to interpret. I'm worried about justifying what is an unfortunately costly operation that may not yield usable data. As for the Merip. always a tough call.

I work with the obvious lanyard. A ri-di the same as yourself. A spare kit biner that holds my pantin & ropeguide. A quickdraw sling with two biners. (Can't rely on anyone else to have one in a rescue.) First Aid Kit. A good book 'cos my groundies are sooooo quick.

You told me to join up or have my legs broken. Been here ever since...

I'm not a Picus operator but a root level cross section might not show any defects, as all the decay may be on the underside of the structural roots. Speaking of picus testing, I have another beech utterly mishapen, loads of adaptive growth, looks like a bundle planting or similar. Problem is, at some time or another someone has filled a large (150m by 70cm) cavity with concrete. And meshed it so the tree has enveloped the mesh. If I get the job, does anyone know whether a Picus could tell me anything about the cavity or would the concrete give misreadings?
-
Bummer dude.
-
Yep. Even if you took the tree out and ground out the stump. Could take decades could happen next year. Replant with a different species, I have a list somewhere of resistant (not immune!) species that would be suitable. Good idea to get them in now if there is space, so the overlap of tree ages is not so severe. You did the right thing telling her that they're on the way out. All things die and fall apart, cycle and life and all that. Put new trees in, start the cycle again. blah blah blah Meripilus can be spread though root contact.
-
There was an article a while ago by Andrew Cowan in whch he described the use of an Airspade to investigate the main structural roots of a large Beech with Meripilus. The investigation concluded no significant decay and it was decided to undertake a light reduction to minimise further risk. Difficult call to make though, with all that history of Beech and Meripilus. What's the target area like?
-
It's hard to sell but mulching (properly) out to the drip line is the best (only?) thing you can do. Its tends to be (especially at the moment) my standard mantra. I look on it as the equivalent of your GP telling you to have a few days off work in bed when you feel like crap. Not going to cure the illness but gives you the time and ability to fight it off yourself.
-
If that the same tree/fruiting body in both pics guys then its either Meripilus giganteus or at a stretch Grifola frondosa. G. frondosa is not so common on Beech as M. giganteus but both form an intense white rot on the underside of structural roots. Either way bad news.
-
Ha, we have something similar... "Looked like a toothless weasel chewing a lemon with pins in it." That's the houseproud owner who's just heard that you can't remove ALL the sawdust from their garden without returfing it.
-
Yep, took the old crap sheath off with scissors (v. carefully!!). Then used my splicing kit to pull the velocity sheath over the webbing, lots of insulation tape around the ends and then as you say a bit of heat shrink to stop the tape peeling off in the rain. Its on so tight, it ain't going anywhere, the tape's to stop the ends unravelling. Good idea, I'll update this thread in a week with another pic. (Probably with it in bits!)

bolle silium dirt cheap in bulk off ebay. http://images.google.co.uk/images?gbv=2&svnum=10&hl=en&sa=X&oi=spell&resnum=0&ct=result&cd=1&q=bolle+silium&spell=1 I have a set of ESS advancer goggles for the big sawdust takedowns http://images.google.co.uk/images?gbv=2&svnum=10&hl=en&q=ess+advancer+v12 No sweat in your eyes with those bad boys but you do look like a fly.

Having read a post on the buzz; http://www.treebuzz.com/forum/showflat.php?Cat=0&Board=UBB2&Number=93033&Searchpage=4&Main=92330&Words=Lazarus2&topic=&Search=true#Post93033 and having knackered the sheath on my Dragonfly bridge I thought I'd have a go myself with a bit of velocity. Turned out pretty good, if I don't say so myself!!!

Maybe it would be instructive for your article to examine the reasons for one handing? I use one hand when I'm out of the kickback line and the follow through won't hit me or my kit. My other hand is usually holding onto something for balance. I often use a saw one-handed when smacking out conifer hedges which I'm fairly sure is the most dangerous thing I do apart from driving. Again the other hand is holding on for balance.
